1. Field of the Invention
The present invention relates to a PCMCIA card type recording apparatus, and more particularly, to a recording apparatus to transmit and receive data through a PCMCIA port and to allow replacement of a disk cartridge on which the data is recorded.
2. Description of the Related Art
A recording apparatus to record and reproduce data on and from a disk type recording medium has been developed in various ways. Examples of such recording apparatuses include a floppy disk drive (FDD), a hard disk drive (HDD), and the like. The FDD records and reproduces, magnetically, data on and from a magnetic disk held in a case. The HDD rotates a hard disk mounted in a case at a high speed to magnetically record and reproduce the data.
Compared with the FDD, the HDD has a superior performance in view of a data transmission speed and a memory capacity, and is used as a main memory unit of a computer. However, unlike the FDD, which is easily carried and mounted in computers, the HDD has shortcomings in that it occupies a large volume, and lacks portability. Due to this, most computers have both the HDD and FDD.
In addition to the portable laptop computer, other compact and portable machines such as a camcorder, a digital camera, a game machine, a personal data assistant, and the like have been developed and come into wide use. Accordingly, there has been a growing demand for a recording apparatus to be used in the above-described machines to record and reproduce the data, and which is compact.
However, since the above-described machines have a small inner space, the FDD and the HDD cannot both be used in the portable machines. Accordingly, the portable machines include a separate FDD, which has to be always carried. The separate FDD is generally cumbersome. Accordingly, a PCMCIA card type recording apparatus, which transmits and receives data with a product such as a computer or the like through a PCMCIA port, is used in the product instead of the FDD.
A conventional PCMCIA card type recording apparatus comprises a removable housing that is connected through a PCMCIA port of a product such as a computer or the like, a disk type recording medium held in the housing, a head and a head arm to record or reproduce the data on or from the disk type recording medium, a head driving mechanism to drive the head and the head arm, and a control circuit board. The PCMCIA card type recording apparatus can be used as the FDD or the HDD according to the kind of the disk type recording medium held therein.
However, the conventional PCMCIA card type recording apparatus has the recording medium fixed in the housing. Accordingly, if a memory capacity is running short and an additional capacity is required, the PCMCIA card type recording apparatus itself has to be replaced. The replacement of the PCMCIA card type recording apparatus causes problems in increased cost for replacement and in having to prepare a certain space to keep the replaced recording apparatus.
In order to solve the above and other problems, an object of the present invention is to provide a PCMCIA card type recording apparatus enabling replacement of a disk cartridge holding a disk when requiring an additional memory capacity, thereby reducing a cost for the replacement of the disk cartridge and allowing the convenience of the keeping and using the disk cartridge.

The embodiments are described below in order to explain the present invention by referring to the figures.
Referring to
Also, there is a connector 13 disposed at one end of the housing body 11. The connector 13 may be inserted into a PCMCIA port to be connected to a product such as a computer. For example, when the housing 10 is inserted into the PCMCIA port of the computer (not shown), the connector 13 is connected to a corresponding connector in the PCMCIA port (not shown) such that the connector 13 transmits and receives various electric signals with the connector in the PCMCIA port. It is understood that other types of signals, such as optical signals, could also be used. Further, it is understood that the PCMCIA port generally refers to a port compliant with PCMCIA cards, PC Cards, Cardbus, Miniature card, CardBay, and other similar devices and standards.
Referring to
At a center of the seating section 14, a disk driving section 30 is disposed to rotatably drive the disk-type recording medium 25 in the disk cartridge 20.
Also, at a center of the disk-type recording medium 25 in the disk cartridge 20, a disk clamp 23 is disposed. The disk driving section 30 includes a rotor and a stator (not shown), and also a magnet (not shown) disposed on a surface on which the disk clamp 23 is placed. Accordingly, if the disk cartridge 20 is mounted on the disk driving section 30 on the housing 10, the disk clamp 23 is magnetically attracted to the disk driving section 30 by a magnetic force, and then the disk-type recording medium 25 rotates as the disk driving section 30 rotates.
A recording/reproducing unit 40 has a head 41, a head arm 43 having a pivot hole 44, and a voice coil 45. The head 41 may be an optical head or a magnetic head, depending on the type of the disk-type recording medium 25. The head 41 in the shown embodiment of the present invention is an optical head. The optical head 41 is disposed on one end of the head arm 43. The voice coil 45 is disposed on the opposite end of the head arm 43 and includes a voice coil motor with a magnet (not shown). The pivot hole 44 is formed at a center of the head arm 43 such that the head arm 43 rotates about the pivot hole 44.
If the disk cartridge 20 is mounted in the housing 10, the disk-type recording medium 25 in the disk cartridge 20 is rotatably mounted on the disk driving section 30. When the disk cartridge 20 is mounted on or removed from the housing 10, the recording/reproducing unit 40 recedes to a position so as not to interfere with the disk cartridge 20. If the disk cartridge 20 is completely mounted in the housing 10, the shutter 27 is opened and the recording/reproducing unit 40 is loaded toward the disk-type recording medium 25.
When the disk cartridge 20 is mounted in the housing 10, the protection cover 50 is positioned at the seating section 14 to protect the disk cartridge 20, and when the disk cartridge 20 is not mounted in the housing 10, the protection cover 50 is positioned above the seating section 14 to protect a component in the housing 10 and to prevent dust from entering. The protection cover 50 may include a buffering element (not shown), such as a sponge, therein depending on the circumstances.
Here, the recording apparatus further includes a removal preventing mechanism to prevent the protection cover 50 from being removed from the housing 10 when the disk cartridge 20 is mounted on the housing 10. The removal preventing mechanism has elastic pieces 57 formed at each lower sidewall of the protection cover 50, and corresponding protrusions 17 formed at the housing body 11. When the protection cover 50 is closed, the protrusions 17 are secured to the elastic pieces 57 by snap-fastening so that the protection cover 50 is not removed from the housing 10.
However, although it is described that the elastic pieces 57 are formed at the protection cover 50 and the protrusions 17 are formed at the housing 10, it is understood that there may be like variations in construction in which the protrusions 17 are formed at the protection cover 50 and the elastic pieces 57 are formed at the housing 10 or combinations thereof. Also, although the two elastic pieces 57 are disclosed as being disposed at each side of the protection cover 50, the elastic pieces 51 may also be disposed at a front and/or a rear of the protection cover 50, at the front and the rear and the sides of the protection cover 50, or any combination thereof.
The seating section 14 also includes a position determining mechanism to determine a seating position of the disk cartridge 20. Referring to the embodiment of the present invention shown in
The seating section 14 further includes a movement preventing mechanism to prevent the disk cartridge 20 from moving or being removed from the seating section 14. The movement preventing mechanism may comprise a plurality of magnets 19 disposed at the seating section 14. In this case, the case 21 of the disk cartridge 20 is made of metal or has a plurality of magnets (not shown) therein corresponding to the magnets 19 such that the disk cartridge 20 is securely seated on the seating section 14 by a magnetic force. However, it is understood that the seating section 14 need not contain both the position determining mechanism and the movement preventing mechanism in all aspects of the invention.
As shown in
It is understood that while it is described that the disk cartridge 20 is connected to the housing 10 by the snap-fastening of the plurality of elastic protrusions 16 into the holes 22, the protrusions or holes may be formed on sidewalls of the seating section 14 and a corner of an undersurface of the disk cartridge 20 such that the disk cartridge 20 is connected to the housing 10 by the snap-fastening. In addition, although the elastic protrusions 16 are formed on the housing 10 and the holes 22 are formed on the disk cartridge 20, there may be another construction in which the holes 22 are formed on the housing 10 and the elastic protrusions 16 are formed on the disk cartridge 20. Also, although the two elastic protrusions 16 are formed on the seating section 14 of the housing 10, the number and positions of the elastic protrusions 16 can be properly determined as required.
Also, instead of using the cylindrical protrusions 15 to determine the seating position of the disk cartridge 20 as shown in
According to the embodiment of the present invention shown in
Like the embodiment shown in
According to the above construction, the disk cartridge 20 is mounted on a seating section 14 in a manner that, when the protection cover 250 is opened, the disk cartridge 20 is mounted in the opened protection cover 250 by insertion as indicated by the arrow, and then the protection cover 250 holding the disk cartridge 20 is connected to a housing 10. Like the embodiment of the present invention shown in
While not shown, it is understood that, although the elastic pieces 157 and 257 are formed on the protection covers 150 and 250 and the protrusions 28 are formed on the disk cartridge 20, the protrusions 28 may also be formed on the protection covers 150 and 250 and the elastic pieces 157 and 257 may be formed on the disk cartridge 20 or any combination thereof. Also, although the two elastic pieces 157 and 257 are formed on each side 152 and 252 of the protection covers 150 and 250, the elastic pieces 157 and 257 may be formed on a front and/or a rear of the protection covers 150 and 250, or the front or rear and the sides 152 and 252 of the protection covers 150 and 250 or any combination thereof.
Since the disk cartridge 20 is mounted in the same manner as that of the embodiment shown in
Although the protection cover 160 of
According to the embodiments shown in
In addition, while not shown, it is understood that the protective cover 50 and the disk cartridge 20 could be sold as an integrated cover such that the recording medium is held by the integrated cover without requiring a separate disk cartridge 20.
As described above, according to the present invention, the recording apparatus is easily mounted in a portable product such as a laptop computer, camcorder, digital camera, and game machine. Also, the recording apparatus according to the present invention is a portable, PCMCIA card-type recording apparatus that allows replacement of a disk cartridge holding a disk when additional memory capacity is required, thereby reducing a replacement cost for the disk cartridge and allowing the convenience of the keeping and using the same.
