  • Rotational Drive Of Disk (AREA)

Abstract

PURPOSE:To eliminate the attracting state of a head and a disk by a sliding operation and to start the rotation of the disk by controlling the driving current of a spindle motor for rotating the magnetic disk by a current control circuit and sliding the magnetic head on a disk surface in a seek direction when the disk cannot be rotated by this driving current. CONSTITUTION:In the magnetic head and a magnetic disk assembly HDA 11, the driving means of the spindle motor 1 consisting of a motor driving circuit 6 and the current control circuit 7 is disposed. A signal from a host device is received by the interface 13 of this magnetic disk device to control the motor 1 of the HDA 11 by a control circuit 12 according to a command from the host device. At this time, at the time of the start of the motor 1, the supply of a small current is instructed to the current control circuit 7 and a command for sliding a carriage 4 is applied to a sliding control circuit 9 at the time of starting no motor 1 by this current. Then, the attracting state of the magnetic head 3 and the magnetic disk plate 2 is eliminated by the sliding operation and the disk plate 2 is rotated without a damage.
