Abstract
A disc drive comprises a drive motor mechanically coupled to a disc and a voice coil motor mechanically coupled to a read/write head on the disc. A power integrated circuit is electrically coupled to the drive motor and the voice coil motor. The power integrated circuit includes an integrated temperature sensor that provides a temperature output. A control circuit receives the temperature output and provides a voice coil motor control output to the power integrated circuit as a function of the temperature output.
