Title: Magnetic head drive device for magnetic disk device
Inventor: KISO MATAICHIRO
IPC: G11B21/02
Filed: 1985-05-14
Abstract: PURPOSE:To avoid stress from concentrating on some part of a band by setting the rigidity of a supporting member giving tension to the steel band lower in the longitudinal and other directions of the band and causing the supporting member to have a freedom degree in two directions. CONSTITUTION:Since a twist plate is adopted as the supporting member of an actuator arm, a top end part 9B has the freedom degree of bending in the longitudional direction of the steel band 7. As the plane of a base part 9C points the shaft 6 of a stepping motor, the freedom degree of bending cam make also in this direction. Accordingly, even when the projection 9D of the twist plate 9 deviates from an appropriate position due to errors in terms of part machining, and even when the retaining openings 72 and 73 of other steel band 7 deviate, the twist plate 9 can freely bend. Thus the concentrated stress will not apply to the steel band 7.
