Abstract
To be capable of precisely positioning a head on a track of a high-density disk rotated at high speed in the disk drive, a head suspension has a plate (3) to be attached to a carriage of the disk drive and turned around a spindle, a load beam (5) having a rigid part (11) and a resilient part (17) and supported by the plate, a front end of the rigid part applying load on a head (13) that writes and reads information to and from the disk, a flexure (7) supporting the head, and an extension (15) having a length (L2) and extending from the plate along the rigid part of the load beam toward the head. The flexure is supported at least by the extension of the plate, and at least supporting the flexure.
