Abstract
The skews in a hard disk drive are optimized by a method including the steps of: initializing a measurement position on a disk to obtain a skew value; initializing a skew table; moving a transducer head to a corresponding measurement position; obtaining an optimal value of track skew and cylinder skew; determining whether the current head position is a last measurement position; when the current head position is not the last measurement position, selecting the next measurement position and returning to the head moving step; and when the current head position is the last measurement position, storing the obtained optimal skew value in a predetermined area of said drive or a memory device. As a result, the time for reading and writing information from and to the disk is sharply reduced.
