ABSTRACT:
A CPU instructs a VCM driver, a spindle motor driver and a servo data reading or writing circuit, to writing servo data for error detection at any of default rotation frequencies stored in a memory. A positioning error signal analyzer detects a positioning error from the written servo data for error detection, and CPU determines an optimal disk rotation frequency from this positioning error.
