ABSTRACT:
A rotary seek magnetic head assembly includes a rigid arm section mounted at one end on a rotary shaft. A load beam element is joined to the other end of the rigid arm section, the element having a portion substantially resilient adjacent to the rigid arm section. The load beam element is rigid over its length from the resilient portion to a point where a looped load bearing section is joined to present a loading force thereon. The looped load bearing section is formed with two arms extending from the load beam element to a cross leg which runs substantially parallel to the direction of rotary seek and is formed with a protuberance. A gimbal spring has a pair of outer flexible fingers which are joined at their first ends to the looped load bearing section and joined at their second ends by a cross leg from which a central finger extends. All the fingers of the gimbal spring runs parallel to the direction of rotary shaft to minimize bending forces which might occur during high speed accessing movements. The central finger is in contact with the protuberance and supports an air bearing slider of U-shaped cross section.
