Method and apparatus for initializing operation of a disk drive |
摘要 |
A motor controller comprises an angular position module that determines an angular position of a disk. A spin-up module performs a spin-up of the disk. A ramp-up module ramps up a speed of the disk after the spin-up. A speed control module controls the speed of the disk based on a control program that is downloaded to the motor controller during a boot-up operation of a disk drive. The angular position module determines the angular position of the disk before handover of control to the control program.
