ABSTRACT:
A magnetic disk apparatus includes a low-rotation mode for decreasing the revolution number of a disk, in the low-rotation mode, any control signal for decelerating the disk is not generated to permit it to be decelerated owing to inertial drive and when a detected speed falls below a target speed, the disk is accelerated to thereby realize power saving.
