The invention designed to improve the precision in determining the position of the magnetic head and to enable more stable maintenance of the gap between the transducer and the recording disk is characterized in that the flange provided to the transducer supporting arm is made lower in height on the rigid arm side than on the magnetic head side.

Flanged transducer supporting arm for a magnetic head/arm assembly

An actuator for a magnetic disk device causes movement of a magnetic head in the radial direction of a rotating magnetic disk. Although this magnetic head is floated above the magnetic disk by a stream of air induced by the rotation of the magnetic disk at a high speed, an excessively high velocity of the air stream causes excessive vibrations of a soft gimbal resiliently supporting the magnetic head. In the actuator of the present invention, a head arm supporting the magnetic head through the gimbal is formed with a wind-breaking projection preventing direct impingement of the air stream against the gimbal and magnetic head, thereby minimizing vibrations of the gimbal and magnetic head.
