| The operating and other procedures of a disk or recording medium application system of the type for which a network is used are simplified. Disks or recording media have auxiliary data recording areas, where different IDs for individual disk, and/or cipher keys and/or decoding keys for ciphers are recorded in advance in a factory. By using the IDs to release the soft ciphers, and using the cipher keys when sending the ciphers, and using the decoding keys when receiving the ciphers, user authorization procedures are simplified. | ||||||

| The present invention is a method and apparatus for securely storing data on a compact disk-like device that can interface with existing compact disk players, digital video disk players and disk drives commonly found on personal computers. The apparatus comprises a compact disk plastic substrate having a microprocessor, a system memory, a data memory and a power source embedded thereon. An optical interface device is embedded on the bottom of the substrate and is electrically connected to the microprocessor. The optical interface device comprises an imaging sensor for receiving data from the laser mechanism of a compact disk drive mechanism to store on the present invention, and a micro mirror array for emulating the pits and lands on a standard compact disk that can be read by the laser mechanism as the data retrieved from the present invention. The method of the present invention consists of both storing data received at the optical interface device in the data memory and transmitting data retrieved from the data memory from the optical interface device. The use of a microprocessor in the transfer of data to and from the data memory enables use of data encryption techniques to encrypt the data stored in the data memory and decrypt date retrieved from the data memory. In addition, passwords may be associated with the data stored in the data memory to further prevent unauthorized access to, or copying of, data stored in the data memory. | ||||||
