Head suspension having cutting surface that is not deburred in actuator attaching area of base plate, method of manufacturing base plate of the head suspension, and method of manufacturing the head suspension

摘要

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.

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 of the base plate, has a front end being longitudinally proximal to the load beam, a rear end being longitudinally distal to the load beam, and a link being longitudinally connected to and extending between a widthwise center of the front end and a widthwise center of the rear end,the actuator attaching area is formed along the longitudinal direction of the base plate and between the front end and the rear end of the base plate so as to be disposed adjacent to sides of the link in the width direction of the base plate, andthe link includes both a longitudinal central part of the link that extends linearly in the longitudinal direction of the base plate and is positioned so as to extend along the sides of the link in the width direction of the base plate, and recesses at portions of the link that longitudinally adjoin respective longitudinal ends of the longitudinal central part of the link so that the longitudinal central part of the link spans linearly from at least one of the recesses to another of the recesses so as to be contiguous with at least two of the recesses.
