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.
摘要翻译：利用用于将可旋转存储装置的换能器定位在磁盘的伺服轨道上的伺服系统，提供了一种用于处理定位脉冲信号的列车的方法。在固定的持续时间内，产生具有预定模式的随时间变化的参考电压，并将其与包含在持续时间内的定位脉冲信号的列进行比较。通过对定位信号的数量进行计数，定位信号的数量随着换能器与要引导的引导路径的位移而变化的大小，是通过计数超过参考电压模式的定位信号的数量给出的。因此，伺服系统的误差信号以数字形式反馈。该方法由于其简单性和用户需求的灵活性而导致装置的成本降低。

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.
