Title:
記録再生装置および信号処理回路
Document Type and Number:
Japanese Patent JP4536412
Kind Code:
B2
Abstract:
A recording and reproducing apparatus (20) includes an RLL encoder (207) an RLL decoder (237).The RLL encoder (207) encodes an information bit string to a code bit string of a run-length-limited code at a high encoding rate satisfying a plurality of constraints regarding a string of successive zeros. The RLL decoder (237) decodes the code bit string encoded by the RLL encoder (207) to the information bit string.
