Abstract
First and second gimbal springs are used for following precisely a magnetic head slider held by a head holder on a recording surface of a rotating magnetic disc. The head slider is held on a front surface of the first gimbal spring at the center and a pivot is fitted on the center of the second gimbal spring and the end of the pivot is contacted with the rear surface of the first gimbal spring at the center and the first and second gimbal springs are in flat in a free condition. During the working time when contacting the head slider with the recording surface in a floating condition, the gimbal spring in the side of the recording surface is in substantially flat whereas during the non-working time, both gimbal springs are formed to expand to both sides.
