Abstract
A hard disk apparatus wherein one of two second actuators is expanded and the other is simultaneously contracted to bend a supporting member in a width direction orthogonal to a length direction of the supporting member to generate a displacement and a vibration of the supporting member in the direction orthogonal to the length direction. When a smooth surface of a magnetic head sticks to a record surface of a magnetic disk, the magnetic head receives a force in the width direction of the supporting member in a plane substantially parallel to the record surface by the expansion and contraction operation of the second actuators to reduce the sticking between the magnetic head and the record surface.
