摘要： An actuator supports a head at one end of a rotatably supported shaft unit and supports a coil of a voice coil motor at the other end, and moves the head to an arbitrary track position of a recording medium. A sensor, attached to a coil support unit of the actuator, detects the coil vibration and outputs a vibration detected signal. A control unit controls the actuator to reduce a head position error signal based on the vibration detected signal of the sensor in time of seek and in time of settling of moving the head to a target track position on the medium through drive of the actuator and drawing the same. The vibration detected signal of the sensor includes bending vibration component of the coil and the twisting vibration component of the coil when the actuator is driven.

摘要： A rotary actuator for positioning magnetic heads in a disk drive, comprising a stator assembly and a rotor assembly. An arm assembly having magnetic heads are fixed to the rotor assembly, which rotates back and forth within a limited angle range around a fixed axis of the rotary actuator due to the forces between plural magnets and driving current which flows though flat coils. Two flat coils are aranged on an arcuate inner surface of the stator such that two adjacent vertical parallel portions thereof closely contact with each other. Two flat coils have an electrical connection with a driving source that the currents through the two adjacently parallel portions flow in the same direction. Three permanent magnets are disposed on the rotor surface, the central magnet having a greater lateral width than that of other two side magnets, and a polarity of the central magnet is opposite to that of other magnets. In another embodiment, each of flat coils comprises an inner coil and an outer coil resulting in enhancing the torque of the rotary actuator. Several modifications of coil and permanent magnet arrangement, and other related improvements in the structure thereof are also disclosed.

摘要： A plurality of HDDs 12-1˜12-n connected around a host 10 can be made to directly communicate with each other. For example, an HDD 12-1 makes another HDD to perform long distance seek using this communication line and measures the influence of vibration caused at that time. The measurement result is formed into a transfer function indicating the position change of the head of the relevant HDD against the operation of another HDD. An HDD is actually driven by a current value obtained by correcting the normal driving current of the driving motor of the head by the transfer function.

摘要： An actuator having a simple configuration requiring no high dimensional accuracy, high in positioning accuracy and low in cost, and a head-positioning mechanism using the actuator are disclosed. An actuator according to a first application comprises a shear-type piezoelectric element of predetermined thickness and an opposed electrode formed on two electrodes in spaced relationship on a base member. The opposed electrode is displaced in accordance with the direction of polarization of the shear-type piezoelectric element upon applying a voltage between the two electrodes. The opposed electrode thus constitutes an operating section of the actuator. An actuator according to a second application comprises a movable member arranged on a drive member including a shear-type piezoelectric element on a base member. The drive member includes a plurality of layers of piezoelectric elements polarized in alternately opposite directions perpendicular to the thickness of the devices. A plurality of conductive layers are formed adjacently to the respective layers of the devices to permit voltage application thereto. The movable member can be driven in parallel to the base member upon application of a voltage between the conductive layers. Any one of these actuators can be incorporated as a part of the head actuator to constitute a head-positioning mechanism capable of displacing the head by a minuscule distance independently of the operation of the head actuator.

摘要： A semicircular packing comprising a metallic portion and an elastic portion sealing the pierced hole of the cylinder head when setting, having thick portions at both ends of auricules and a thin portion between thick portions at both ends, at least on the metallic portion partly contacting with the outer surface of the pierced hole. This semicircular packing is easily conformed to the curved peripheral surface of the pierced hole and makes it unnecessary to coat it with sealing liquid as well as able to permit the clamping torque of the cylinder head to be small and yet maintain its sealing state over a long term of years without being subjected to excessive or premature aging.
