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 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 suspension for disk drive, comprising a load beam having a proximal end portion fitted with a base plate, a distal end portion fitted with a flexure, and bent edges formed individually on the opposite sides thereof, the load beam being gradually tapered from the proximal end portion toward the distal end portion, a support projection interposed between the load beam and the flexure, and a flexible portion of the load beam defined in a region between the support projection and the base plate. Openings are formed in an inner portion of a second region between the center of gravity of the flexible portion and the base plate, inside the bent edges, so that K.sub.Lb /K.sub.SP is 2 or more, where K.sub.Lb is a spring constant for a first region between the center of gravity of the flexible portion and the support projection and K.sub.SP is a spring constant for the second region, the area of the openings accounting for 25% or more of the area of the inner 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.
