Abstract

A method of manufacturing a base plate, after deburring and heat-treating a half-finished base plate, cuts off a scrap section at the ends of the scrap section from a half-finished actuator attaching area so that cutting surfaces left in a finished actuator attaching area are positioned onto the inner perimeter of the finished actuator attaching area and are oriented to at least partly face an actuator attaching position inside the finished actuator attaching area.

First claim

What is claimed is:

1. A head suspension comprising:
a base plate that has an actuator attaching area being an opening in the base plate;
a load beam supported with a resilient part connected to the base plate and supporting a read/write head;
an actuator attached at an actuator attaching position in the actuator attaching area; and
an adhesive fixing the actuator to the actuator attaching position, in which
the base plate comprises a width and, in a longitudinal direction…
