Abstract: A head suspension for a disk drive has a base (19) to be attached to a carriage, a load beam (21) having a rigid part (27) and a resilient part (29) supported by the base, to apply load on a data read/write head (13) arranged at a front end (27a) of the rigid part, and a flexure (49) attached to the load beam and supporting the head. The rigid part has a multilayer structure consisting of at least three layers including metal layers (28a, 28b) and a resin layer (28c) interposed between the metal layers. The number of layers of the resilient part is smaller than that of the rigid part.

Abstract: A suspension for disc drive comprises a base portion, a beam portion formed of the same material as the base portion and made thinner than the base portion by partial etching, and a hinge member connecting the base portion and the beam portion to each other. In manufacturing this suspension, a platelike semi-finished suspension, which integrally includes a base portion, a beam portion, and a connecting portion connecting the base portion and the beam portion to each other, is first manufactured. The thickness of the beam portion of the semi-finished suspension is reduced by partial etching. Thereafter, the base portion and the beam portion are connected by means of the hinge member, and moreover, the connecting portion is separated from the base portion and the beam portion.

Abstract: A suspension comprises a baseplate having a boss portion, a beam portion with a flexure, and a hinge member. The hinge member includes a connecting portion that can bend in the thickness direction thereof between the baseplate and the beam portion. If the length of the suspension from a pivot portion on the distal end portion of the beam portion to the center of the boss portion is 14.5 mm, the thickness of the baseplate is 0.175 mm or greater, the width of the baseplate is 4.5 mm or greater, the length of the connecting portion of the hinge member is 0.7 mm or shorter, and the length of the baseplate is 5.04 mm or shorter.

Abstract: A suspension for disc drive having a micro actuator mechanism comprises a base plate, a connecting plate having a hinge portion thinner than the base plate, a load beam provided with a flexure, a pair of actuator elements such as PZT, etc. The micro actuator mechanism includes a pivot portion formed between a pair of slits and support walls formed on the connecting plate. The actuator elements are provided individually on the opposite sides of the pivot portion. Each support wall is a bent portion that is formed by raising an edge portion of the connecting plate in the thickness direction of the main portion of the connecting plate.
