Abstract

A magnetic head 1 supported on a spring suspension 2 is loaded and unloaded relative to a magnetic disk 3 by means of a rotatably mounted unit having unloading pins 4 which ride over a load/unload cam surface 5 on the suspension 2. The magnetic heads 1 are normally loaded on the magnetic disk 3 surface by the spring force of the suspension 2, two of which are attached to each access arm 6 so that both sides of the magnetic disk 3 can be accessed. The unload mechanism includes a load/unload cam surface (or ramp) 5 which is attached to each suspension 2. A rotatably mounted unit 7 having unloading pins 4 is fixed in position next to the head/arm assembly just outside the disk pack.
