Method for recording reference servo information of hard disk drive, method for recording final servo information of hard disk drive, hard disk drive therefor, and recording medium therefor

摘要

The present invention is self-servo writing a final servo information using the servo reference information in the hard disk drive If the record relates to a method in particular comprising a plurality of reference servo information are adjacent to each other there is an error in one of the reference servo information with reference to another adjacent reference servo information recording method for recording servo information and the final servo information, thus for the hard disk drive ., and to a recording medium ; reference to the hard disk drive according to the present invention the servo information recording method includes the step of providing the reference servo information for the first and the second having a different frequency; And comprising the step of writing the first and second servo reference information in a predetermined position of the disk, wherein the first and second reference servo information is recorded at regular intervals in each track direction on the disc, the adjacent is characterized in that the record to the second reference servo information is located between the first reference servo information. ; reference servo information recording method according to the present invention, the plurality of reference having a different frequency By writing the servo information to the adjacent one of the error if the reference servo information has the effect that can occur using a different one of the reference servo information to improve the yield by the hard disk drive to record the final servo information.
