Abstract
A head suspension for a disk drive is capable of improving shock property of the hard disk drive while miniaturizing the hard disk drive. A head suspension has a base plate to be attached to a carriage and turned around a spindle of the carriage, a load beam which includes a beam and a hinge, a base end of the beam being supported to the base plate through the hinge and which applies a load onto a head for writing and reading data to and from a disk at a front end side thereof, and a flexure which connects the head to writing and reading wires and supports the head and which is attached to the load beam, where the hinge is set to be relatively thicker than the beam so that the load beam is made thin and the load is increased.
Claims5
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;
- 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 that is supported with 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
- a thickness of the resilient part is set to be relatively greater than that of the rigid part so as to thin the load beam and increase the load applied onto the head.
