Title: Off-track signal generating device, and off-track signal generating method
Inventor: SUZUKI TAKAMASA
IPC: G11B7/085
Filed: 2002-08-19
Abstract: <P>PROBLEM TO BE SOLVED: To generate an appropriate off-track signal even when the off-track signal can not be generated from the bottom holding signal of an RF signal conventionally due to that pitches of lands/grooves formed on a disk signal surface are equal to each other.  <P>SOLUTION: The off-track signal is a signal indicating that a laser spot to be irradiated on a disk signal surface is positioned at the outside of tracks. The off-track signal has fixed relational property with the waveform of a tracking error signal TE to be obtained at the time the laser spot traverses tracks. That is, the off-track signal is made into a signal to be inversed in response to the peak level of the tracking error signal TE . Thus, the device is constituted as that the peak timing of the tracking error signal TE is detected and the off-track signal is obtained by inversing the signal with the detected peak timing based on this relational property.  <P>COPYRIGHT: (C)2004,JPO
