ABSTRACT:
In the high-speed seek mode in which priority is given to making the seek operation faster, the CPU sets the driving voltage applied to a motor driver that drives both a spindle motor and voice coil motor to a first driving voltage. Furthermore, in the high-efficiency mode in which priority is given to reducing the power loss in the motor driver, the CPU sets the driving voltage applied to the motor driver to a second driving voltage lower than the first driving voltage.
