Title: Magnetic disk device
Inventor: KAWABE SHIN
IPC: G11B21/21
Filed: 1983-10-03
Abstract: PURPOSE:To improve the assembling performance of a magnetic disk device without giving any damage to both a magnetic recording disk and a magnetic head, by using a drive mechanism which can move freely the magnetic head even in the direction vertical to the magnetic recording disk. CONSTITUTION:A shape memory alloy body 7 is attached to a head suspension 3. When a current is supplied to a lead wire 8, the body 7 is heated up and changes its own shape. As a result, the suspension 3 also changes its shape to decrease the distance between a pair of upper and lower magnetic heads 2. Under such conditions, an actuator 5 is moved toward an arrow head and the heads 2 are put between magnetic recording disks 1. Then the current flowing to the wire 8 is reduced gradually. Thus the body 7 loses its own shape deforming power and has deformation in an opposite direction by the spring power of the suspension 3. Therefore each head 2 can have the stable landing on the disk 1.

In this case, when the speed deviation is positive (or negative), a conduction rate command and a DC voltage command are simultaneously increased (or decreased) and an acceleration (or deceleration) time is reduced.  Then, when the speed deviation reaches zero after acceleration, the DC voltage command is decreased, and at the same time the conduction rate command is increased, and a converter circuit 2 and an inverter circuit 3 are controlled so that a switching loss can be reduced and at the same time loss due to the pulsation of a motor current can be reduced.
