ABSTRACT:
A flexure assembly for mounting and supporting a read/write head in a rigid disc drive data storage device. The flexure assembly includes a main flexure member which has a rigid beam and a gimbal portion integrally formed using the processes of etching and half-etching. A load transfer extension is fixedly attached to the rigid beam of the main flexure member, and is used to transfer a balancing force to counteract the self-acting hydrodynamic air bearing which is an integral part of the head. Application of the balancing force is through a load point button formed using the half-etching process on the tab used to adhesively mount the head. Attachment of the load transfer extension to the rigid beam is accomplished using either adhesives, or, preferably, an arrangement of tabs which are bent into cooperative arrangement with alignment features, thus eliminating the need to weld a separate gimbal member to a flexure load beam.
