ABSTRACT:
A method for reading/writing data of a disk drive that includes a spindle motor for rotating a disk and a head for reading/writing data from and to the disk. The method includes the steps of; (i) adjusting a position of the head for the first time to space apart the head from a center of the disk at a specific distance, wherein when the head is spaced apart from the center of the disk at the specific distance, the disk vibrates at the minimum magnitude during raising operation of the spindle motor from a low speed to a high speed; (ii) raising the spindle motor from the low speed to the high speed; and (iii) adjusting a position of the head for the second time to move the head to a desired track in the disk for reading/writing data in the desired track.
