摘要： A carriage for a disc device, which has a top arm, bottom arm, and mid arm, has a main mode, end arm mode, and mid arm mode as a frequency response obtained when subjected to a vertical shake. In the main mode, all of the top, bottom, and mid arms swing at a first frequency within the same phase in a primary bending mode. In an end arm mode, the top and bottom arms swing at a second frequency higher than the first frequency within opposite phases and with an amplitude larger than that of the mid arm. In the mid arm mode, the mid arm swings at a third frequency having a difference of 50 Hz or less from the second frequency within the same phase as in the main mode, and the top and bottom arms swing within the phase opposite from that in the main mode.

摘要： A suspension for a disc drive has a load beam, a flexure, a slider, etc. A tongue portion and a pair of outrigger portions are formed on the flexure. Slits are formed between the outrigger portions and opposite side edges of the tongue portion. The tongue portion and the outrigger portions are connected by connecting portions. Limiter members are formed on the load beam. Each limiter member has a bent portion, which is inserted in its corresponding slit, and an extending portion. The extending portion faces its corresponding connecting portion. A trace member is electrically connected to the slider. The trace member passes outside the limiter members and extends along the outrigger portions.

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： According to one embodiment, a magnetic disc apparatus includes a magnetic head which reads information stored in a magnetic disc, an arm which supports the magnetic head, and a feedback controller which controls a coarse actuator to move the magnetic head above the magnetic disc by driving the arm, a fine actuator to hold a position of the magnetic head, and a feedback path which feeds back a displacement of the actuator to a target value of the coarse actuator. The feedback controller controls decoupling of a double actuator system which adds up the coarse actuator and the fine actuator.

摘要： A method of attaching a head assembly having an annular hollow boss to an arm having a through hole of a carriage is provided. The head assembly includes a load beam of a head suspension and a base plate fixed to a base part of the load beam. The boss is formed on the base plate. The method includes steps of, inserting the boss into the through hole, thereby setting the head assembly to the arm of the carriage, supplying lubricant along the cylindrical jig to the caulking ball and pushing the caulking ball with the cylindrical jig to pass the caulking ball through an inside of the boss and diametrally expand and plastically deform the boss, thereby fixedly fitting the boss of the head assembly to the through hole of the arm of the carriage. The method causes no deformation of a flange formed on the base plate during caulking and is achievable at low cost.
