Filed: 2003-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To determine the execution/nonexecution of waveform equalization based on the detected value of tangential skewing.  <P>SOLUTION: An RF signal is reproduced and amplified in step S1, and tangential skewing detection described later by using FIG. 10 is executed in step S2. In step S3, based on a tangential skewing detected value α, determination is made as to whether tangential skewing between an optical disk and an optical pickup part is within a predetermined value or not. When it is determined that the skewing is not within the predetermined value, the RF signal is supplied to a waveform equalizing part in step S4, and waveform equalizing is executed in step S5. When the tangential skewing is determined to be within the predetermined value, after the end of the processing in step S5, the supplied signal is subjected to run-length correction in step S6, and the corrected signal is decoded in step S7. The invention is applied to the optical disk playing device.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
