Abstract

A memory chip and embedded microprocessor (‘smart memory card’) with a sputtered memory ring for additional memory capacity. The card configuration allows use with ISO 7816 compliant readers. The smart memory card has a spring bolt-hole which allows use of the smart memory card on an adaptor with compact disc and digital video disc drives. The memory chip and sputtered memory ring have sufficient capacity for high-density memory applications such as high-level encrypted security systems, biometric identification systems, and combination access systems. The processor configuration may include a wireless transceiver for 802.11 series, Bluetooth™ and other wireless systems.

DETAILED DESCRIPTION

FIG. 1 shows the first planar surface of the smart memory card (100). The card may be made from a standard 120-mm diameter polycarbonate compact disc with a thickness of 0.60-mm. The disc is then cut to the size of a standard credit size so that the center of the 15-mm spring bolt-hole (110) is located 37.75-mm (130) from one length-wise edge and is 47.75-mm (170) from the opposite length-wise edge. The spring bolt-hole (110) is then 10-mm off-center length-wise.

A smart memory chip (120) is placed on the first planar surface of the smart memory card (100) so that the nearer adjacent probes of the smart memory chip (120) are located a distance (140) according to ISO 7816. The far adjacent probes are then located a distance (180) also according to ISO 7816.

This memory chip (120) configuration allows the smart memory card (100) to be inserted into a standard ISO 7816 smart memory card reader and still allow ample space for a sputtered memory ring on the opposing side.

FIG. 1 b shows the second planar surface (200) of the smart memory card (100). A sputtered ring (250) of optical read and write recording material is laid on this second planar surface (200) around the spring bolt-hole (110). Those skilled in the art will appreciate that the sputter ring is made using standard DVD technology. This sputtering is performed with standard sputtering equipment and then covered with a hard thermoplastic or thermo set material in order to protect against surface scratching. Additional thickness may then be added with hard coat, bringing the overall thickness of the smart memory card (100) to approximately 0.760-mm thick.

FIG. 2 shows the disc adaptor (300) in detail for communicative coupling of the smart memory card (100) to a compact disk or digital video disc (DVD) drive. The adaptor disc (300) is cut to size from a blank CD disc.

The smart memory card (100) rests in an adaptor cavity (330) of the adapter (300) as shown in FIG. 2b. Tabs (220) on the outer edge hold the smart memory card (100) on one side. The off-center spring bolt-hole (110) of the smart memory card (100) lines up with adaptor disc hole (310) to complete an aligned secure hold of the smart memory card (100) in the adaptor (300). The smart memory card (100) is also locked in the cavity (330) with the spring lock (240).

Probe pins (350) align with, and communicatively connect the smart memory chip (120) to the bottom side of the adaptor (300).

FIG. 2 a shows the top side of the compact disc and digital video disc adaptor (300) for the smart memory card (100). The probe pins (350) communicatively couple the smart memory chip to the adaptor optical circuitry (410). The adaptor bus memory ring circuitry (400) communicatively couples the probe pins (350) to the adaptor bus memory rings (400).

FIG. 2 c shows the smart memory card (100) placed into the adapter cavity (330) on the adapter disc (300). The smart memory chip (120) side is face up. In this profile they appear as a single disc, so the card and adaptor may be inserted into a standard compact disc or digital video disc (DVD) drive.

FIG. 3 shows the adapter disc (300) placed into a compact disc or digital video disc (DVD) reader tray (640). The side holding the smart memory card (100) is placed face down. Tray guides (600) may be used to hold the adapter disc (300).

The adaptor optical circuitry (410) communicatively couples the smart memory card (100) to the disc drive, while the adaptor bus memory rings (400) communicatively couples with the disc drive optical (420, 630 and 620).

These connections address the identification security programmed on the smart memory chip (120) to control use of the compact disk or digital video disk (DVD) drive with the smart memory card (100). If the identification of the user is not confirmed, the disc drive will not be allowed to read or write the data from the sputtered memory ring (250) of the smart memory card (100).

This probed connection is similar to the ISO 7816 smart card reader. The advantage of the smart memory card is that it requires only one insertion for reading the smart memory chip (120) and also accessing the data on the sputtered memory ring (250).

FIG. 4 shows the disc adapter (300) fitted with an adaptor wireless booster (700) for use of the smart memory card (100) incorporating a wireless communicative system. Such a wireless communicative system could be a PHILIPS MIFARE PROX interface, which is ISO 14443A compliant. Alternative embodiments of the wireless communicative system include the 802.11 series, Blue Tooth™, and R-F short-range systems.

This contact-less smart memory card reader works by placing the smart memory card in proximately to the adaptor wireless booster (700) on the disc adapter (300) in the compact disc or digital video disc (DVD) drive. The wireless communication system transceiver is then placed in proximately to the compact disc or digital video disc (DVD) drive. This wireless communication system eliminates the need of a probe to connect to the smart card chip.

FIG. 5 shows a compact disc or digital video disc (DVD) drive (800) with a wireless receiving antenna (810) located separate from the drive. The drive loading door is (710).
