摘要： The method for manufacturing a suspension for disc drive includes a process for manufacturing a semi-finished suspension product integrally including a base plate, a rigid body portion of a load beam, and a pair of connecting portions connecting the base plate and the rigid body portion. The method also includes a process for fixing a spring member, formed independently of the semi-finished suspension product, to the base plate and the rigid body portion of the semi-finished product, and a process for cutting off the connecting portions, projecting individually from the opposite sides of the spring member, from the base plate and the rigid body portion after the spring member is fixed to the semi-finished suspension product.

摘要： A suspension for disc drive comprises a base plate, a load beam attached to the base plate, and a flexure attached to the load beam. The load beam includes a rigid body portion, formed of a thick plate independent of the base plate, and a spring portion, formed of a spring member in the form of a thin sheet independent of the rigid body portion. The spring member connects the rigid body portion and the base plate. The spring member is thinner than the rigid body portion and has a lower spring constant. The spring portion is more flexible than the rigid body portion.

摘要： A head suspension for a disk drive has support plate means (3, 7) serving as a carriage arm and a load beam (5). The load beam consists of a rigid part (13) and a resilient part (15), to apply load to a slider (43) of a head. The support plate means (3, 7) consists of at least layered two plates (3, 7). At least one (7) of the plates (3, 7) has a thickness (t2) appropriate for forming precision holes therethrough by etching. A pivot hole (31) is formed through the plate (7). A loose hole (9) larger than and substantially concentric with the pivot hole is formed through the plate (3). The plates (3, 7) have improved flatness, and the pivot hole has improved accuracy.

摘要： 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.

摘要： 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.

摘要： A suspension for disc drive having a load beam and a flexure is provided with a limiter mechanism for regulating the movement of the flexure. The flexure includes a tongue portion provided with a magnetic head slider and a pair of outrigger portions situated individually on the opposite sides of the tongue portion. The limiter mechanism is provided with a nipping portion that is formed by bending part of the load beam. The nipping portion includes a first checking portion facing one surface of the flexure across a gap, a connecting portion situated ahead of the flexure, and a second checking portion extending rearward from the connecting portion and facing the other surface of the flexure across a gap.
