Inventor: KOBAYASHI TOSHIKAZU
IPC: G11B7/085
Filed: 2002-10-21
Abstract: <P>PROBLEM TO BE SOLVED: To precisely detect the boundary position of a data recorded area and a no recorded area and reliably and quickly reproduce the data without using address signals, regardless of the eccentricity of the disk or the amount of the recorded data.  <P>SOLUTION: The bottom hold circuit 17 generates the bottom hold signals (BH signals)from the RFDC signals of the RF amplifier 16 and supply them to the comparator 18. The comparator 18 compares the reference level and the BH signals and generates H level Rfdet signals if the BH signals are lower than the reference level. The Rfdet signals become H level when the laser spot is within the area having recorded data on the disk 40, but becomes L level when the laser spot is in the area having no recorded data. The servo microcomputer 22 drives the optical pickup 11 for tracking servo control upon detecting the Rfdet signal is H level for one rotation of the disk.  <P>COPYRIGHT: (C)2004,JPO
