Abstract:
A disk drive configured to control spindle spin is provided. The disk drive includes a spindle motor for spinning a disk configured for storing data, a nonvolatile memory comprising instructions associated with a first process for spin-up of the spindle motor from a power-on mode and the nonvolatile memory comprising instructions associated with a second process for spin-up of the spindle motor from a power save mode, a controller for determining which of the first or the second process for spin-up of the spindle motor to implement in accordance with the instructions stored in the nonvolatile memory and a motor driver for spinning up the spindle motor according to the first process or according to the second process for spin-up of the spindle motor.
