ABSTRACT:
A head suspension for a disk drive has a base plate (19) to be attached to a carriage of the disk drive and a load beam (21) consisting of a rigid part (27) and a resilient part (29), to apply load onto a slider. The rigid part and resilient part are separately formed. The rigid part is joined to a first side (29a) of the resilient part. The suspension also has a reinforcing plate (37) to hold and fix a second side (29b) of the resilient part between the reinforcing plate and the base plate. The base plate stably and resiliently supports the load beam. This suspension satisfies required characteristics.
