Abstract

A system is disclosed for storing data on, and receiving data from, an optical disk. The data may be provided by a host computer. A compression/decompression circuit is included, and the data may be compressed or uncompressed in this circuit, at the option of a user, who can select from compression modes including a bypass mode and a target ratio mode. A converter circuit is included for translating from the host computer's commands to the optical disk drive's commands. The user may select a specific emulation for compatibility with other disk systems, and the user may select specific setup parameters for compatibility with a variety of host computers. Process control circuitry operates the compression and decompression circuit in one of a number of modes and emulations. The system may be enclosed in a full form factor size package. A display and manual controls, accessible to a user, are provided for user interface with the system. Many user options are provided to enhance compatibility with a wide variety of disk systems. The present invention provides a large storage capability for storing large amounts of information in less physical space. The system of the present invention is suitable for ''plug and play'' installation by computer manufacturers. As an additional advantage, the user can easily monitor data compression with the display that shows the compression ratio, continuously updated.
