ABSTRACT:
A disk drive apparatus includes a driving circuit which rotates a recording media having a disk shape, and a read/write head movable in a radial direction of the recording media and a vertical direction substantially perpendicular to a plane of the radial direction. The read/write head writes data on the recording media and reads data therefrom. The disk drive apparatus also includes an initialization unit which initializes the read/write head during a period until the recording media starts to rotate and the rotating speed of the recording media reaches a predetermined constant speed so that the disk drive apparatus is set to a read/write enable state where the read/write head is correctly positioned with respect to the recording media in order to correctly write data on the recording media and read data therefrom.
