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 head suspension for a disk drive has a load beam, a base plate, and a recess. The base plate has a thin flange and is capable of improving the attaching accuracy and strength of the head suspension to a carriage arm of the disk drive. The base plate (3A) has the flange (7A) and a boss (9). The flange has a contact face (23A) to be attached to a contact face (39) of the carriage arm (35). The boss is inserted into a hole (37) of the carriage arm and plastically deformed therein to fix the base plate to the carriage arm. The load beam has a rigid part and a resilient part and is supported by the base plate, to apply load on a slider arranged at a front end of the load beam. The recess (31A) is formed on the base plate along a corner (29) between the flange and the boss, to secure a gap relative to the contact face of the carriage arm.

Abstract translation: 磁盘驱动器的磁头悬架具有负载梁，基板和凹部。 基板具有薄的凸缘，并且能够提高磁头悬架对磁盘驱动器的滑架臂的安装精度和强度。 基板（3A）具有凸缘（7A）和凸台（9）。 该凸缘具有一个接触面（23A），该接触面（23A）将被安装到该支架臂（35）的接触面（39）上。 凸台被插入到支架臂的孔（37）中并在其中塑性变形以将基板固定到支架臂上。 负载梁具有刚性部分和弹性部分，并被基板支撑，以将负载施加在布置在负载梁前端的滑块上。 所述凹部（31A）沿着所述凸缘和所述凸台之间的角部（29）形成在所述基板上，以相对于所述滑架臂的接触面确保间隙。
