Abstract
A data recording and reproducing method for an optical disk data storage system to record data compressed at different data compression rate according to an operator'"'"'s specification, and to reproduce the recorded data by decompressing. According to the operator'"'"'s indication, the data is recorded at certain data compression rate in indicated area. The information of the data compression rate and the recorded area is stored as a table of contents (TOC) data. The TOC data is reproduced and stored in a memory after the optical disk is loaded. The recorded data is reproduced by selecting a decoding circuit to decompress the data. The decoding circuit is selected by referring the TOC data to identify data compression rate of the recorded data. Also the TOC data is referred to identify read-in and read-out region of the recorded data. The position of a pick-up when the data recording is started and ended, is recorded as the TOC data to provide random access capability for the data reproduction.

7. An optical disk adapted to be coupled to an optical disk drive and usable in association with a processor coupled to the optical disk drive, said optical disk causing the processor to:
-
i) retrieve a table of contents data written on said optical disk;
ii) store the retrieved table of contents data into a memory;
iii) from the table of contents data stored in the memory, identify a data encoding technique and a layer and a location in which recorded data is stored;
iv) read out and route the recorded data at the identified layer and the identified location to a data decoder; and
v) decode the read out recorded data in reference to the identified data encoding technique. - View Dependent Claims (8)
