Device and method for compensating for interhead track position offset due to the offset of tracks on disk surfaces

摘要

A servo sampling timing generating circuit of a disk drive recording apparatus having a plurality of heads, wherein servo information for measuring interhead track position offset generated in head switching is recorded on a predetermined cylinder on disks in an embedded sector servo mode is characterized in that a final head selection signal and a servo sampling enable signal for sampling the servo information recorded on respective tracks constituting the predetermined cylinder are generated whenever a servo address mark is detected.
