Title: Head controller and disk device using it
Inventor: YAMAMOTO HIROSHI
IPC: G11B7/09
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To reduce an infleunce on a servo characteristic of a phase delay and a quantization error due to digitally processing. SOLUTION: A low band component EFL is extracted from a focus error signal EF by a filter 202, and the processing of gain adjustment and phase compensation are performed digitally for the low band component EFL by a DSP(digital signal processor) 204, and a low band focus control signal DFL is obtained. On the other hand, a high band component EFH is extracted from the focus error signal EF by the filter 206, and the processing of the gain adjustment and the phase compensation are performed digitally for this high band component EFH by circuits 207, 208, and a high band focus control signal DFH is obtained. Then, the control signals DFL, DFH are added by an adder 209, and a final focus control signal DF is obtained.  An upper limit of a servo band doesn't depend on the processing power of the DSP, and further, the large phase delay doesn't occur by a delay due to the inside operation time of the DSP. Further, the quantization error in an A/D converter doesn't affect a high band head control signal with a small displacement amount perfectly.
