MAGNETIC STORAGE CONTROL APPARATUS, MAGNETIC STORAGE CONTROL METHOD, AND MAGNETIC STORAGE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a magnetic storage apparatus, a magnetic storage control method and a magnetic storage device which can reduce an error of a recording clock.;SOLUTION: The magnetic storage control apparatus for controlling a magnetic storage apparatus that uses a recording medium having a plurality of reference signals on its track and having a data area between the reference signals. The apparatus includes: a measurement section that reproduces the reference signal in a predetermined track of the recording medium and measures, for each data area, the time for a head to scan the data area to obtain a measurement value; a calculation section that calculates a setting value concerning the frequency of a recording clock used in data recording based on the measurement values of a plurality of data areas measured by the measurement section; and a generation section that generates the recording clock based on the measurement values measured by the measurement section and setting value calculated by the calculation section.;COPYRIGHT: (C)2010,JPO&INPIT
