ABSTRACT:
A disk drive includes media for recording data, disk heads for recording data and reproducing data on the disks. The heads are supported on arms. A head actuator drives the arms moving the head to a predetermined data recording track on the disk. A spindle motor rotates the disk at a predetermined rotating speed. The spindle motor includes a rotor magnet disposed within a stator coil. The disk head and actuator motor are mounted on a pivot on opposed sides of each other. To control head positioning, first positioning data for positioning the disk heads and second positioning data are provided on each data surface. This data is detected by a data head. Second positioning data may be positioned on tracks not used for containing data. The head position is compensated by the stored second positioning information superimposed on the first positioning data.
