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.

DVD Forum, DVD Book Construction (www.dvdfllc.co.jp/bookcon.pdf —printed Sep. 2005). This listing of “DVD Specifications” refers to the “DVD Specification for Read-Only Disc” which may be dated as early as Aug. or Sep. 1996, through this information should not be construed as an admission that the “DVD Specification for Read-Only Disc” was “published” as of this date. Because the official DVD Specification books are available only after signing a nondisclosure agreement and paying a $5,000 fee (www.dvdfllc.co.jp/howto.htm), it is Applicant's understanding that the nondisclosure agreement provisions prohibit Applicant from submitting a copy of the DVD Specification documents. In any event, Applicant does not have a copy of the referenced DVD Specification documents. Contact DVD Format/Logo Licensing Corporation (DVD FLLC) at www.dvdfllc.co.jp for additional information.
