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 present invention relates to a recording method in particular comprising a plurality of mutually adjacent servo reference information there is an error in one of the reference servo information with reference to the other 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 servo information recording method of the hard disk drive according to the present invention the step of providing a plurality of reference servo data having a different frequency; And it writes the servo reference information in a predetermined position of the disk, in which is characterized in that the plurality of the reference servo information in a track direction to be adjacent to each other includes the step of recording a predetermined interval. ; This invention reference servo information recording method according to the so if there is an error in one of the reference servo information by recording a plurality of adjacent servo reference information having a different frequency, using a different one of the reference servo information should be written to the last servo information By having the effect to improve the yield of the hard disk drive.
