Abstract
A disk apparatus in which a control unit performs a seek control includes a disk motor which rotates a disk placed at a loaded position in the disk apparatus. A motor driver controls the disk motor such that the disk is rotated by the disk motor at a controlled speed. A read/write head reads information from or writes information to the disk when the disk is rotated by the disk motor at the controlled speed. A head shifting unit shifts the head in a radial direction of the disk to a target location thereof when a seek is performed. A current supply control unit controls current supplied to the disk motor during the seek. In the disk apparatus, the current supply control unit cuts off the current supply to the disk motor for a predetermined period after a start of the seek.
