Abstract:
1. A method of manufacturing a head suspension of a hard disk drive, the head suspension including a base to be attached to a carriage of the hard disk drive and turned around a spindle, a load beam including a rigid part and a resilient part separated from the rigid 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, the rigid part extending from a front end to a base end part thereof, said base end being connected to the resilient part that is supported with the base, a flexure having read/write wiring patterns connected to the head, the flexure supporting the head and being attached to the load beam, a joint provided on the base end of the rigid part and having a protrusion that extends and protrudes from each side of the base end of the rigid part laterally, the joint being connected to the resilient part, and reinforcing parts each expanding and connecting between each of the protrusions and a middle portion of the rigid part between the front end and the base end thereof, the method including: forming a resilient member comprising the resilient part separately from the rigid part, the resilient member integrally including a branch portion extending between the joint of the rigid part and the base, an extension extending from the branch portion so as to overlap with the middle portion of the rigid part, and a reinforcing part formed on each side of the extension; connecting a first end of the branch portion, a second end of which is connected to the base, to the joint of the rigid part; and connecting the extension on the middle portion of the rigid part, to dispose the reinforcing parts between the protrusions and the middle portion of the rigid part, respectively.
