Patent ID: 7636221

Claim:
A head suspension, comprising: a base to be attached to a carriage of a hard disk drive and turned around a spindle of the carriage, the base having an arm; a load beam including a rigid part and a resilient part, to apply load onto a head that is arranged at a front end of the load beam to write and read data to and from a disk arranged in the hard disk drive, a base end of the rigid part being connected to the resilient part, and the resilient part being supported by the arm; and a flexure having read/write wiring patterns connected to the head, the flexure supporting the head and attached to the load beam; wherein each of the rigid part and the resilient part is made from a same single layer plate, and a thickness of the single layer plate at the resilient part is set to be relatively greater than a thickness of the single layer plate at the rigid part so that part of the load beam is made thin and part of the load beam has an increased spring load.
