Process for computing eccentric amount of disk upon rotating |
摘要 |
A process for computing an eccentric amount of a disk upon rotating is provided. The process includes steps of starting a servo control system of a disk drive to rotate the disk at a specified angular velocity, measuring a track crossing speed of the servo control system at a focusing point on the disk, and computing the eccentric amount of the disk according to the specified angular velocity and the track crossing speed. A process for controlling rotation of a disk loaded in a disk drive is also provided. The process includes steps of realizing an eccentric amount of the disk, and rotating the disk at an operating speed corresponding to the eccentric amount.
