Abstract:
The method of manufacturing a disk drive suspension load beam adapted to be mounted to an actuator and to carry a flexure and slider, including shaping the general form of said load beam, said load beam having a longitudinal axis extending in a longitudinal plane, a rearward spring portion adapted to be mounted to an actuator, a forward portion to carry a flexure, and a rigid intermediate portion therebetween, forming edge rails on said rigid intermediate portion; and transversely trenching said load beam in its rearward and intermediate portions to define a longitudinal series of parallel lands and grooves disposed transversely of said rearward portion and of a number, spacing, depth and width to substantially occupy the entire surface of said portions to increase said load beam flexible rearward portion lateral and torsional stiffness while reducing said rearward portion resistance to bending from said longitudinal plane, said grooves being open and of unchanged width from their depth to the face of said load beam where said flexure is to be mounted.
