摘要： The magnetic head supporting mechanism includes a head positioning actuator having an arm and a load beam. The load beam (235) comprises a substantially rectangularly-shaped plate having at least one opening and an attachment portion, the opening defining at least one beam portion (31-34) and a slider fixing portion (30). The slider fixing portion is connected to the plate through the beam portions for flexibly supporting a head slider used in the magnetic disk drive. The attachment portion is provided for attaching the load beam to a load arm (22) used in the magnetic disk drive. A conductive wiring pattern (91-94) is formed on the plate, e.g. by photolithography.

摘要： The apparatus overcomes head positioning errors generated when the enclosure makes rotating movement due to translational vibration input resulting from vibrations. A vibration proof mechanism consisting of a plurality of vibration proof supporting members (5′) is provided between the enclosure (4) and the frame (5) of the device. The vibration proof supporting members are disposed so that the linear moment around the center of gravity of the enclosure is balanced against translational external force applied to the enclosure.

摘要： A retracting assembly produces a constant torque, in a data zone of a magnetic disk, which is greater than static friction of a bearing for a rotary actuator. However, in a parking zone on an outer portion of the magnetic disk, the retracting assembly generates a torque which suddenly increases so that a large holding torque is obtained and a magnetic head is reliably locked.

摘要： With a servo system for positioning a transducer of a rotatable storage apparatus over a servo tracks of a magnetic disk, a method for processing trains of positioning pulse signals is provided. With a fixed duration time, a reference voltage, changing with time, having a predetermined pattern is generated and compared with a train of the positioning pulse signals contained in the duration time. The magnitude of the positioning signals which varies with the displacement of the transducer from a guide path to be followed is given by counting the number of the positioning signals exceeding the reference voltage pattern. Thus, an error signal for the servo system is fed back in a digital form. The method causes cost reduction of the apparatus because of its simplicity and flexibility for the users' demand.

摘要： A head assembly (24) for a disk drive having an increased resonant point in a seek direction achieves high-accuracy positioning of a magnetic head slider (26). The head assembly (24) includes a load beam (28) having a spring portion (28a) having a first thickness, and a rigid portion (28b) having a second thickness. The second thickness, which is greater than the first thickness, may be realised by affixing a reinforcing plate (44) to a portion of the load beam (28), or it may be realized by simply integrally forming the load beam (28) with two different thicknesses. A gimbal (34) is fixed to a front end portion of the load beam (28), and a head slider (26) is mounted on the gimbal (34). The gimbal (34) may be integral with the load beam (28). Preferably a plurality of signal lines are formed by printing on the load beam (28).

摘要： A rotating support apparatus in a disk storage device is provided with a stationary shaft (1), ball bearings (2, 2′) rotatably fitted on the stationary shaft, a rotatable member (3, 40) rotatably supported by and on the ball bearings, and buffer rings (8, 8′) superimposed between the associated ball bearings and the rotatable member to absorb a thermal deformation of the rotatable member due to a change in a temperature. The buffer rings have a same coefficient of linear expansion as that of the material of which the rotatable member is made, and each of the buffer rings is in contact, at two points with one of the rotatable member or outer race of the ball bearing, and at one point with the other of the rotatable member or outer race of the ball bearing. This allows the buffer ring to flex axially to absorb differential thermal expansion.
