Claims

[Claims for Utility Model Registration] A belt is wound α around a pulley of a seek motor of a magnetic disk device, and as the pulley rotates, the first belt portion, which is one of the extending portions of the belt, In a mechanism for moving a head carriage from a reference position by being wound around a pulley and a second belt part, which is the other extending part, being let out from the pulley, the belt is moved between the first belt part and the second belt part. A pair of ears extending from both sides in the width direction of the belt is provided at the base of the belt, and the belt is fixed to the pulley by screwing the pair of ears respectively. A head carriage moving mechanism for a magnetic disk device configured as follows.
