Method and system for recording data on and reading data from an optical medium

A method for reading data from an optical medium, comprising:

• locating a section of data by scanning the optical medium for a SYNC 0′ byte and a SYNC 1′ byte, the SYNC 0′ and SYNC 1′ byte each being selected from the following group:
• 00000000001000, 00000000001001, 00000000010000, 00000000010001, 00000000010010, 00001000000000, 00010000000000, 00100000000001, 01001000000000, 10001000000000, and 10010000000000, the SYNC 1′ byte being different from the SYNC 0′ byte, the SYNC 0′ and SYNC 1′ bytes being such that at least one of the following conditions is met:
• (a) the SYNC 0′ byte is not equal to 00100000000001, and (b) the SYNC 1′ byte is not equal to 00000000010010;
• and
• reading the section of data from the optical medium.

An optical medium recording system comprising:

• a Cross Interleave Reed-Solomon Code (CIRC) encoder operable to receive and encode a first plurality of frames of data to generate a second plurality of frames of data;
• a control block operable to add a control byte to each one of the second plurality of frames of data to generate a third plurality of frames of data;
• an eight-to-fourteen modulation (EFM) encoder operable to receive the third plurality of frames of data, and operable to encode selected portions of the third plurality of frames of data to generate a section comprising a plurality of Channel frames, the EFM encoder being further operable to replace the control byte of a sequentially first one of the third plurality of frames of data with a SYNC 0′ byte selected from the following group:
• 00000000001000, 00000000001001, 00000000010000, 00000000010001, 00000000010010, 00001000000000, 00010000000000, 00100000000001, 01001000000000, 10001000000000, and 10010000000000, the EFM encoder being further operable to replace the control byte of a sequentially second one of the third plurality of frames of data with a SYNC 1′ byte selected from the following group:
• 00000000001000, 00000000001001, 00000000010000, 00000000010001, 00000000010010, 00001000000000, 00010000000000, 00100000000001, 01001000000000, 10001000000000, and 10010000000000, the SYNC 1′ byte being different from the SYNC 0′ byte, the EFM encoder being further operable to select the SYNC 0′ and SYNC 1′ bytes such that at least one of the following conditions is met:
• (a) the SYNC 0′ byte is not equal to 00100000000001, and (b) the SYNC 1′ byte is not equal to 00000000010010;
• and
• a recording mechanism operable to receive the section and to record the section on the optical medium.
