Patent ID: 7124496

Claim:
A method of manufacturing a head suspension for a disk drive, the bead suspension having a base plate to be attached to a carriage of the disk drive, a load beam consisting of a rigid part and a resilient part, to apply load onto a slider, the rigid part and resilient part being separately formed, a base end of the rigid pan being laid on and joined to a first side of the resilient part, and a reinforcing plate, the reinforcing plate and base plate being mounted to a second side of the resilient part to hold the second side of the resilient put between the reinforcing plate and the base plate, the method comprising: a first step of forming small holes in at least one of the base plate and reinforcing plate; and a second step of welding the base plate, resilient part, and reinforcing plate by emitting laser beams into the small holes, to fix the second side of the resilient part between the base plate and the reinforcing plate.
