Abstract: A system that redefines how data is distributed on a conventional writable compact disc (CD-R/E). A rearrangement of the data on the disc provided during the writing operation preserves eight-to-fourteen channel frames and the control and display (C&D) channel and burst error mitigation while providing a direct access storage device (DASD) format and capability. The CD-DASD format is suitable for preformatting the CDs and has constant size sectors recorded contiguously along the spiral track. Each sector is independently addressable and synchronous with the C&D data word and ATIP channel words on the CD-R disc. The system uses the components of a conventional CD device and a mapping controller address translator to encode and decode the data bytes using a conventional CIRC encoder/decoder. A rectangular product code of C1 and C2 CIRC subcodes is provided that is interleaved to mitigate the effects of handling.
