Abstract
A positioning method positions a flexure whose front end side is joined to an outside frame with respect to a load beam, keeps the positioned state of the flexure and load beam, plastically deforms the outside frame to bead the front end side of the flexure so that the position of a tongue of the flexure is adjusted to the position of a dimple of the load beam, and joins the flexure and load beam to each other to keep the position adjusted state of the tongue.

-10. (canceled)
A half-finished head suspension comprising:
- a flexure having a head attaching part defined at a front end side for attaching a read/write head;
- a load beam laid on and joined to the flexure and having a supporting part of a load beam positioned with respect to the head attaching part;
- and
- an outside frame joined to a front end side of the flexure;
- and
- manufactured by a method comprising steps of:
- positioning the flexure with the respect to the load beam and keeping the positioned state of the flexure and load beam;
- plastically deforming the outside frame to bend the front end side of the flexure so that the position of the head attaching part of the flexure is adjusted to the position of the supporting part of the load beam;
- joining the position-adjusted flexure and load beam to each other to keep the position-adjusted state of the head attaching part;
- wherein the plastically deforming step is carried out by irradiating areas defined on the outside frame with laser beams;
- and
- the joining step joins the position-adjusted flexure and load beam to each other, thereby forming the half-finished head suspension in which a head suspension is connected to the outside frame.
