摘要： PROBLEM TO BE SOLVED: To equalize stably a reproduced signal to a target partial response waveform even when reproduction conditions such as tilt or beam diameter are varied in PRML detection being effective for high density reproduction. SOLUTION: Equalization is performed by the least square technique by using a predetermined number of data samples binarized by a viterbi decoder 3. Even when data written on an optical disk are unknown, the data can be equalized in a stable manner and can be reproduced at a low error rate without instability factors such as divergence due to interference.

摘要： PROBLEM TO BE SOLVED: To attain a reproducing device which surely prevents reproduction of illegal digital content. SOLUTION: A content check part 102 discriminates whether a value of a pointer included in an EVOBU read from storage media is larger than the total number of hash values existing in a hash table CHT by every EVOBU. If the value is larger, reproduction of the digital content is stopped. In addition, the content check part 102 calculates a hash value of a selected EVOBU by every EVOBU selected with prescribed probability from a group of EVOBUs read from the storage media, and determines whether the calculated hash value coincides with the hash value stored in entry of the hash table CHT. In the case of unmatching, reproduction of the digital content is stopped. COPYRIGHT: (C)2007,JPO&INPIT
