Title: Servo signal generator and disc drive employing it
Inventor: WACHI SHIGEAKI
IPC: G05D3/12
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To improve the servo characteristics by performing a process for obtaining a high band servo signal at a sampling rate and performing a process for obtaining an intermediate/low band servo signal through intermediate/low band compensation of the high band servo signal at a rate lower than the sampling rate thereby shortening the sampling period. SOLUTION: A focus error signal EF is sampled at a sampling period TS and subjected to A/D conversion and then it is subjected immediately to high band compensation to produce a high band focus control signal DFH. It is then added to a newest intermediate/low band focus control signal DFL to produce a focus control signal DF which is converted into an analog signal and outputted. Immediately after addition, a part of intermediate/low band processing and other processing are effected. More specifically, the intermediate/low band processing is effected intermittently during the second time of each sampling period comprising a plurality of sampling periods.
