In the magnetic head movement mechanism consisting of the actuator arm that swings around the pivot axis, the fixing point for fixing the band of the actuator to the step motor shaft is provided in the middle position of the band, shifted from the place where the bands overlap . Features a magnetic head movement mechanism of a magnetic disk device. The brief description of the drawing has been amended as follows. The descriptions of "attached state" on page 6, line 9 and line 13 of the same page of the specification are corrected to "wound state."

Claims

[Scope of utility model registration request]

It has a magnetic head, a head arm that holds the magnetic head, a swing arm that holds the head arm, and a pivot shaft around which the swing arm is attached.The step motor swings around the pivot shaft via a band wrapped around the shaft. A magnetic head moving mechanism comprising an actuator arm that moves the actuator arm, wherein a fixing point for fixing the band of the actuator to the step motor shaft is provided at an intermediate position of the band offset from the extension of the band. Head movement mechanism.
