Disclosed is a self-heating disk drive that comprises a voice coil motor
(VCM), a spindle motor, and a temperature sensor. The VCM includes a VCM
coil and the VCM is configured to move an actuator having a head attached
to a distal end of the actuator. The spindle motor includes a plurality
of spindle coils to spin a disk of the disk drive. The temperature sensor
is used to read an internal temperature of the disk drive. Circuitry is
configured to: command the application of current to the VCM coil without
loading the head onto the disk and to the spindle coils of the spindle
motor in a manner so as not to spin the disk; and, if the internal
temperature reading reaches a pre-determined spindle temperature, the
spindle motor is allowed to spin-up the disk.
