A head suspension for a disk drive includes a base (5) to be attached to a
carriage, a load beam (3) having a rigid part (9) and a resilient part
(11) supported by the base, to apply load on a data read/write head (19)
arranged at a front end of the rigid part, a flexure (7) attached to the
load beam and being provided with the head, and a guide face (27) formed
on an edge (9a) of the rigid part where a jig is inserted, to guide the
jig without wearing away the jig. The guide face is formed by providing
the edge of the rigid part with an integral thin part that is thinner
than the rigid part and bending the thin part, or by partly removing the
edge of the rigid part. The jig is inserted into a head suspension
module, which is made by arranging the head suspension and other
identical head suspensions at regular intervals, such that the teeth of
the jig slide on the guide faces of the head suspensions to maintain
spaces between the rigid parts of the head suspensions, to install the
head suspension module into the disk drive such that the heads of the
head suspensions face disks in the disk drive.
