The present invention relates to devices, methods and systems for restoring optical discs, with an automated pad cleaning mechanism. The invention provides an easy to use device for user's to repair optical discs without having to clean or remove rotating pads in the device between uses, until the life of the rotating pads has expired.
The invention relates generally to restoration and repair devices for optical discs, namely for compact discs (CD's), digital versatile discs (DVD's) and Blu-ray discs. More particularly, the invention relates to methods, devices and systems that effectively restore a compact disc with a self-cleaning mechanism to restore the device after a restoration cycle, for continued repairs. The invention further relates to restoration and repair devices for compact discs with an automated pad cleaning means, for ease of use of a user.
Compact discs are made of several layers, a polycarbonate plastic layer, a reflective foil layer, a lacquer layer and a graphic layer. Data is burned into the polycarbonate plastic layer of a disc, and the next three layers, the reflective foil, lacquer and graphic layer combined are very thin and offer little to no protection against damage to the underlying data in the polycarbonate plastic of a disc. Similarly, Blu-ray discs use a shorter wavelength blue laser for improved reading of discs. Digital information is read from discs by infrared lasers, which reflects data to a laser reader in reflected beams to decode information contained on a disc.
CD's, DVD's and Blu-ray discs often get scratched or obtain fingerprints and blemishes through continued use or by accident. Scratches, imperfections, and gouges on Blu-ray disc surfaces may make data unreadable by laser readers. When this happens music discs skip tracks and DVD's skip frames, which interferes with proper disc playing, interrupting education and entertainment otherwise obtained from the disc. Various machines, methods and processes have been devised and constructed to cleanse or repair discs. The problem with prior art techniques include but are not limited to the following: 1) results in a messy machine, with a long clean-up process for users 2) unable to record and reproduce repaired data faithfully 3) not cost effective and difficult to manufacture, 4) results in waste, 5) raises environmental concerns, 6) not easy to install, use and operate, 7) many existing machines require cleaning or replacement of buffing pads between cleaning cycles, 8) many existing machines cannot repair blue-ray discs, 9) existing machines are meant to clean a disc, but not to actually repair a damaged disc.
As one example U.S. Pat. No. 5,860,181 discloses a method and apparatus for cleaning a work piece by scrubbing a work piece with a cleaning member. The cleaning member is described as an abrasive cloth that removes particles from the work piece in order to clean the work piece.
U.S. Pat. No. 5,954,566 discloses a method and apparatus for repairing a disc by removing material from the protective coating of the disc. The buffing element disclosed in the '566 patent is specifically disclosed to generate a coarse grade and abrading system to remove a protective coating from the disc. Similarly, in yet another reference, U.S. Pat. No. 6,386,946 discloses a compact disc repair system that requires grinding and polishing of the disc in order to repair the disc. Each of the aforementioned patents fall short as technologies unable to faithfully repair discs and machines which are unable to repair Blu-ray discs, or provide a self-cleaning mechanism for withstanding multiple repairs without requiring manual cleaning or replacement of cleaning pads.
Other related U.S. Patent References include U.S. Pat. Nos. 8,045,440; 6,869,344; 7,625,263; and US publication numbers 20060166610, and 20110143636. The 20110143636 application describes a device with intermittent flow of a compound and water for repairing a disc. In accordance with the methods described in this patent application, the intermittent flow of compound and water results in restoration temperatures that typically reaches about 150 degrees Fahrenheit, temperatures that may destroy data on an optical disc. Similarly, the 20110143636 application describes two rotating pads which require removal and cleaning between cycles, thereby creating risk of damage to a disc if a user has not removed and individually cleaned the pads between cycles.
The disc repair system in accordance with the present invention provides for the restoration and maintenance of all known CD Media, DVD's; single or double sided, including 3-inch discs with the use of a 3-inch adapter and Blu-ray discs. The device essentially comprises interaction of rotating pads, a water supply means for pre-moistening the pads prior to a restoration cycle, a continuous flow of abrasive compound during a restoration cycle, a continuous flow of water during a restoration cycle to maintain the restoration temperatures at about 100 to 115 degrees Fahrenheit, and a water supply means for cleaning abrasive compound off of the rotating pads at the end of a restoration cycle, in accordance with the present invention. In addition, in accordance with the present invention, the rotating pads may have one or more grooves, which assists in ease of removal of abrasive compound from the pads. In accordance with the present invention, a user can repair any optical disc, including Blu-ray discs, without having to remove and clean the pads between restoration cycles. In addition, a rotating disc motor in accordance with the present invention spins throughout the restoration cycle, including a final spinning cycle after water is used to remove abrasive compound from the pads, so that the disc is dry when it is removed from the device, for convenience of a user. Accordingly an advantage of the present invention is to provide a disc repair system for quickly and effectively repairing or maintaining all types of scratched or otherwise damaged discs with an automated cleaning system to effectively allow multiple repairs to be made without having to replace cleaning pads in the device. Another advantage of the invention is the ability of a user to repair a disc in one step, with a fully automated system that repairs a disc in a short time period. In accordance with this advantage, the user does not have to wipe, polish or clean the disc by hand. In a method described herein, a compact disc can be cleaned in thirty seconds and repaired in four minutes or less, allowing the user to clean or repair a disc just before playing the disc. As another advantage of the invention, the disc repair device is easily transportable and storable to operate as an attractive front counter device. In yet another advantage, the disc repair device may be used for many uses, for example 125, 4 minute disc repairs or 1,000, 30 second disc cleanings and the liquid catalyst and the rotating pads, water and abrasive compound may be replaced once the maximum uses have been completed, which may be prompted by a notification on the device. The disc repair device is made of durable materials, with an easy to use and aesthetically pleasing user interface, allowing for a long lasting machine with multiple use capacity.

In accordance with this embodiment, the abrasive compound is connected with tubes to a peristaltic pump, which runs continuously during a restoration cycle in accordance with the present invention. Tubes may carry the water and abrasive compound from the water bottle and abrasive compound bottle to peristaltic pumps, which may regulate the flow of water and abrasive compound during a restoration cycle. In addition, tubes may then carry the water and abrasive compound from the peristaltic pumps to one or more release channels, to release the water and compound onto an optical disc. In this embodiment 4 release channels may be provided for optimal cleaning and/or repair, 2 for water release and 2 for abrasive compound release.
Further, in accordance with this embodiment, the rotating pads may be petal-shaped buffing pads with grooves, so that the abrasive compound is easily removed from the rotating pads following a restoration cycle. In accordance with this embodiment, the two pads may be used to restore a disc, which may be used for about 84 minutes of optical disc cleaning and repair. In accordance with this embodiment, two sets of pads may be delivered with the device, so that a user may replace the pads after about 84 minutes of cleaning and/or repair. In addition, a Velcro holder may be placed on a pad holder for ease of installation of the pads. The grooves on the rotating pads may provide for ease of removal of abrasive compound from the pads compared to pads without grooves. In addition, in accordance with this embodiment, the water supply means may be used to pre-moisten the rotating pads prior to the start of a restoration cycle, as water is applied to the surface of an optical disc to pre-moisten the rotating pads 3 to 5 seconds before the start of a restoration cycle. In addition, in accordance with this embodiment, pre-moistening rotating pads may soften the pads prior to a restoration cycle, which may make the restoration cycle safer from any potential scratching of optical discs. In addition, at the end of a restoration cycle in accordance with the present embodiment, water may be applied to the optical disc at the end of a restoration cycle to clean abrasive compound off of the pads in an automated pad cleaning mechanism. For example, water may be applied for an additional 5 seconds or more at the end of a restoration cycle in an automated pad cleaning mechanism. In accordance with this embodiment, automated cleaning of the pads result in ease of use of the device by a user, with the ability to clean and restore discs about 30 to 100 times without having to replace or clean the pads, depending on the severity of damage to a disc.
The embodiment in accordance with the present invention may further include a center seal, which may be located between the rotating pads. In accordance with this embodiment, the center seal may cover the center of a disc during a restoration cycle, so that the center of an optical disc may be protected from water and/or abrasive compound during a restoration cycle. In addition, the center seal in accordance with the present invention may further hold an optical disc on a rubber platter during a restoration cycle, so that the disc remain centered as a rotating motor below the rubber platter spins the optical disc.
The present embodiment may further have a consumable counter chip, which may be located between the buffing solution and the water behind a rear door of the device. The abrasive compound, water and pads may be designed in accordance with the present embodiment to be replaced all at the same time, which may be after about 500 minutes of device operation. The consumable counter chip may be used to identify to a user the amount of consumables water and abrasive compound left in the device during use, so that a user knows when to refill the water and abrasive compound. In this embodiment the consumable counter chip may display the amount of consumable water and abrasive compound remaining on a user interface. The consumable counter chip may show the following indications: 100% full for 376-500 minutes of restoration time, 75% full for 251 to 375 minutes of restoration time, 50% full for 126-250 minutes of restoration time, 25% full for 1-125 minutes of restoration time and 0% full for 0 minutes of restoration time. In accordance with the present embodiment, the consumable counter chip will notify a user when the consumable water and abrasive compound are empty and may prevent any further restoration cycles until the water and/or abrasive compound is replaced and/or a new consumable counter chip is installed.
At the completion of a restoration procedure, water and abrasive compound that has been used in the restoration process may be collected in a catch below the rubber platter of the device. From the catch the water and the abrasive compound may be transferred to a holding reservoir. In the present embodiment, the holding reservoir may hold all of the water and compound solution required to clean discs for about 250 minutes. When the holding reservoir is full, a user may discard of the holding reservoir contents and reuse the holding reservoir for collecting water and abrasive compound from restoration cycles.
In accordance with this embodiment continuous release of water and abrasive compound has several benefits, including but not limited to: 1) continuous flow of abrasive compound allows for optimized disc restoration and friction reduction during the restoration process by decreasing the required pressure of the pads to enable restoration of a disc, 2) continuous flow of water throughout the restoration cycle reduces heat that builds up during the restoration cycle, maintaining the temperature during the restoration cycle at about ten to fifteen degrees Fahrenheit, a safe temperature for optical discs. Similarly the water supply means in accordance with the present embodiment of the invention provides several benefits to the disc restoration apparatus including but not limited to: 1) pre-moistening of the pads prepares the pads for optimized restoration with minimal friction between the pads and the optical disc 2) pre-moistening of the pads helps control heat build-up at the onset of the restoration cycle 3) applying water to the optical disc and pads at the end of the restoration cycle for about fifteen to twenty seconds cleans residue abrasive compound from the pads following the restoration cycle, thereby allowing the user to continue to repair discs without having to manually remove and clean the pads between cycles, for the life of the pads 4) applying water to the disc at the end of the restoration cycle removes any abrasive compound remaining on the disc and 5) applying water to the disc at the end of the restoration cycle removes abrasive compound surrounding the disc, making release of the disc easier for users. In addition, the center seal on the hinged top in accordance with this embodiment has several benefits in accordance with the present embodiment, including but not limited to: 1) it protects the center of the optical disc with an air tight seal, thereby preventing abrasive compound and water from entering the center of the disc during the restoration cycle, which could destroy the disc, 2) the center seal holds the disc on the rotating platform during the restoration cycle, thereby preventing the disc from releasing from the rotating platform during a restoration cycle.

In accordance with another embodiment of the present invention, a method for restoring optical discs is described. The method in accordance with one embodiment of the present invention may include but is not limited to the following steps: 1) pre-moistening rotating pads in an optical disc restoration apparatus, 2) continuously applying an abrasive compound to an optical disc during a restoration cycle, 3) continuously applying water to an optical disc during a restoration cycle, 4) applying water to an optical disc after ending a restoration cycle, 5) ending application of water to the optical disc and 6) rotating the optical disc on a rubber platter to dry the disc for ease of use by a consumer. In accordance with this method, the step of pre-moistening the rotating pads helps reduce heat from friction between the rotating pads and the optical disc during a restoration cycle. In accordance with this method, the first step of pre-moistening the rotating pads is accomplished by applying water to the surface of an optical disc and rotating the pads on the optical disc for about five to fifteen seconds prior to the start of a restoration cycle. In a next step, of continuously applying an abrasive compound to an optical disc during a restoration cycle may help maintain the restoration temperature between the pads and the optical disc to about 110 to 115 degrees Fahrenheit. Continuous application of the abrasive compound further enhances the restoration process by allowing maximal repair of the optical layer of a disc in a short restoration period, for example, in about 30 seconds to about 4 minutes, which may reduce the restoration time by about one minute, compared to devices that intermittently apply an abrasive compound. In a next step of continuously supplying water to an optical disc during the restoration cycle, may assist in maintaining the disc at between about 110 to 115 degrees Fahrenheit. In accordance with the embodiment described, temperature maintenance during a restoration cycle is important, as temperatures greater than 120 degrees Fahrenheit may pose risk of damage to a disc. In particular reconditioning temperatures equal to or greater than 150 degrees Fahrenheit may pose serious threat of damage to a disc. In a next step of applying water to an optical disc after completion of a restoration cycle, abrasive compound remaining on the rotating pads may be washed out of the rotating pads in this steps, thereby leaving the rotating pads ready for reuse without requiring the user to remove the pads and manually clean the pads. In accordance with this embodiment, the pads may be used between about 30-100 times without having to be removed and cleaned, or replaced by a user, making the present method extremely convenient and effective for multiple disc repairs by one or more users. In a last step the optical disc platform may continue to rotate after the water rinsing application is stopped, thereby drying excess water from the disc for a user's convenience.
In another embodiment of the present invention, an automated pad cleaning apparatus for an optical disc restoration apparatus includes but is not limited to the following features: 1) one or more rotating pads, 2) an abrasive compound supply means, wherein the abrasive compound is continuously applied to the surface of said optical disc during the restoration cycle; and, 3) a water supply means, wherein the water is supplied to the surface of an optical disc at least at the end of a restoration cycle, wherein the water cleans the abrasive compound from the one or more pads. In accordance with this embodiment, the rotating pads are petal-shaped pads with grooves, wherein abrasive compound is easily removed from the pads in accordance with the water rinsing methods described, from the spaces in the grooves on the pad.
In accordance with one or more of the embodiments described a convenient and attractive apparatus is provided, so that the device may be readily placed on a users counter as an attractive restoration device, which may also be easily transported. In accordance with one embodiment of the invention, the water bottle and the abrasive compound bottle may be contained within the device, with a door so that a user can replace the water supply bottle and the abrasive compound supply bottle. In addition, in accordance with this embodiment, the front of the machine may have an attractive easy to use user keypad, and two transparent windows showing the peristaltic pumps for supplying water and compound to the device.
