動装置。[Claims for Utility Model Registration] (1) A belt is wound α around a pulley of a seek motor of a magnetic disk device, and a first belt portion of the belt is wound around the pulley in response to rotation of the pulley. In the device in which the head carriage is moved from the reference position as the second belt portion is drawn out from the pulley, a mechanism for absorbing the slack of the belt is provided on the pulley so as to act on the second belt portion. A head carriage moving device for a magnetic disk device having the above configuration. (2) The belt slack absorption mechanism has a groove formed in the part of the pulley around which the second belt part is wound, and a plate spring member is attached in the groove with an elastic force applied thereto. A head carriage moving device for a magnetic disk device according to claim 1, wherein when the belt slackens, the second belt portion is pushed and expanded in the outer circumferential direction of the pulley by the leaf spring member. . (3) Utility model registration claim No. 1 in which the first belt portion and the second belt portion are separate members.
A head carriage moving device for a magnetic disk device as described in 1.
