ABSTRACT:
A compact disc (CD) or CD-ROM disc having at least one surface region containing a field of digitally encoded, reproducible data, outside of a central region of the disc is provided with a second non-volatile read/write memory IC chip or memory device, e.g., an E.sup.2 -PROM, embedded in the central region adjacent to the data field. Input/output (I/O) terminal is also embedded in the central region and provides for communication with and access to the second nonvolatile memory IC chip device. The terminal has one surface exposed adjacent to the data field for external access by a CD or CD-ROM access player or playback apparatus. The terminal has a series contact engagement means through which access is made by complementary terminal means provided in the player whereby the movement of the disc is terminated and information may be read into or read out of the second nonvolatile memory IC chip device. The invention has particular application to CD-ROM disc players employed for audio/video games and for dictionary database applications for word processing.
