Title: Magnetic disk device
Inventor: MATSUURA TSUKASA
IPC: G11B21/12
Filed: 1989-02-01
Abstract: PURPOSE:To eliminate the adhesion between a floating head slider and a magnetic disk together with no working applied to the magnetic disk and therefore to prevent the damage of a magnetic head by securing such a constitution where a projecting part of a suspension rides on the thick part of a flange when the revolution of the magnetic disk is stopped. CONSTITUTION:A suspension 7 has a projecting part 1 at the side opposite to a spindle 8 and holds a floating head slider 6. A ring 2 containing a flange has its thickness varying continuously in the axial direction of the spindle 8 and is fitted to the spindle 8. When the revolution of a magnetic disk 5 is stopped, the part 1 of the suspension 7 rides on the thick part of the flange part. Thus a non-contact state is secured between the surfaces of the slider 6 and the disk 5. As a result, the adhesion is completely eliminated between the slider 6 and the disk 5. Furthermore no special working is required to the disk 5 and a magnetic head itself never rides on the part 1 in a stop state. Thus the magnetic head is never damaged.
