TRACK SEARCH SERVO CONTROL METHOD FOR DISK DRIVE, TRACK SEARCH SERVO CONTROL DEVICE FOR THE DISK DRIVE, THE DISK DRIVE, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a track search servo control method and device for a disk drive for shortening a track search time, while reducing noise in the disk drive, and a track search servo control device.;SOLUTION: In the track search servo control method for the disk drive, the disk drive moves a transducer to a target track using an acceleration trajectory guided by a convolutional operation so that the variation in acceleration at a track search beginning part and a track search end part becomes zero, in searching of the track. Thereby, when an HDD is applied as the example of the disk drive, the transducer can be moved to the target track comparatively quickly, while minimizing mechanical noise in searching of the track, and performance can be improved.;COPYRIGHT: (C)2005,JPO&NCIPI
