Abstract:
1. A method for reading/writing data of a disk drive that includes a spindle motor for rotating an optical disk and a head for reading/writing data from and to the disk, comprising the steps: adjusting a position of the head for the first time in order 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 said specific distance, an average vibration magnitude of the disk is the minimum during raising the rotating speed of the spindle motor from a low speed to a high speed; raising said spindle motor from said low speed to said high speed; and adjusting a position of the head for the second time in order to move the head to a desired track in the disk, thereby starting data reading/writing operation from and to the desired track in the disk.
