Title: Disc drive head driver
Inventor: SUDOU SHINICHI
IPC: G11B21/02
Filed: 2003-05-26
Abstract: The present invention eliminates variations in the engagement between a rack and a pinion, which drive a recording head, to enable the head to move speedily and smoothly. A head driver includes a rack provided on a recording head that slidingly moves over a recording disc and a pinion engaged with the rack and rotated by a drive motor, wherein there are provided a concave groove, provided on the rack and running in parallel with rack tooth, and a swing arm with which a rigid guide, guided by the concave groove, is integrated and on which a rotation axis of the pinion is provided. When the rack is at a slant with the movement direction, the swing arm swings, following the slant of the rack to keep constant the spacing between the rack and the pinion. Because the swing arm is made of rigid material, there is no need for one of the pinion and the rack to be pressed against the other by the spring force. Therefore, no excess power is applied to the gear-mating surface of the rack and the pinion.
