Disk device and disk decelerating and stopping method for the same |
摘要 |
A decelerating method with low power consumption can be selected when rapid deceleration is not required. A disk can be stopped promptly and reliably even when a need arises for stopping the disk during deceleration of the disk by the method with low power consumption. In a disk device having a function of decelerating or stopping a rotating disk, depending on the kind of a command upon decelerating or stopping, the operation for decelerating or stopping is switched between a forced deceleration or stop operation by applying a reverse-directional voltage to a disk motor which rotates the disk so as to forcedly decelerate or stop the disk, and a power saving deceleration or stop operation with lower power consumption than the forced deceleration or stop operation so as to decelerate or stop the disk.
