摘要： In a magnetic head slider having a horizontal type head element which floats on or comes into contact with a recording medium, in which a portion 32 of the slider including the head element can be moved in a minute range in the tracking direction and the loading and unloading direction and is supported by a stationary section 31 forming a slider body via a support spring 34, a leading wire 22 drawn out from the head element 43 is formed in the process of manufacturing the slider so that the motions of the movable section 32 of a microactuator with respect to the stationary section 31 are not obstructed. The lead wire 22 drawn out from the head element 43 mounted on the movable section 32 is composed of a flexible lead wire 22, the rigidity of which is lower than that of the support spring 34, and a leading wire (which is a flexible lead wire 22) is drawn from the movable section to the stationary section so that the movement of the movable section with respect to the stationary section is not restricted.

摘要： A compact and simple lapping apparatus in which, even if projections and depressions are formed in the circumferential direction on the top surface of a lapping plate, a workpiece and a bar are hard to damage and the polished surface of the workpiece is kept in good condition. This apparatus is provided with at least one lapping jig in which a workpiece is placed on the rotating top surface of the lapping plate. Further, a lapping head adapted to be able to rotate only in a direction on the lapping plate is attached to this lapping jig. This lapping head is equipped with a workpiece and at least two dummy work materials (or stock) so that these dummy works compose (as-polished) surfaces, which should be polished, together with the workpiece. Moreover, a device for detecting the remaining part of the workpiece to be lapped is provided on the workpiece. Furthermore, this lapping apparatus is configured so that a detection signal, which represents the detected remaining part of the workpiece and is outputted from the rotating lapping head, is sent to and a correction signal is sent from a control unit to the lapping correction device through a slip ring. A workpiece is polished while rotated on the lapping plate. Thus, the polished surface of the workpiece is kept in good condition.

摘要： A magnetic head which can fly over a surface of a magnetic recording medium comprises a main body fitted into a supporting arm, rail surfaces formed in the main body to serve pneumatic bearings, and projections formed on the rail surfaces and having surfaces opposing a magnetic recording medium. The projections have larger surface roughness than that of the magnetic recording medium, whereby wear-out rate of the projections provided on the magnetic head can be reduced and also the projections can be firmly brought into contact with the surface of the magnetic recording medium.

摘要： In a device which is adapted to write and read an information on and from a recording disk through a head and includes a head actuator for moving the head in a radial direction of the recording disk so as to position the head at a desired recording track on the recording disk, a mechanism for minute movement of a head provided at a part of the head actuator is capable of moving the head a very small distance independently of an operation of the head actuator. This mechanism for minute movement of a head is provided with expansion regions which are arranged symmetrically with respect to a center line of the head actuator and are separated by a clearance. Expansion members which are fixed on both or either of front and rear surfaces of the expansion regions, cause the expansion regions to expand or contract by the deformation thereof produced according to application of the power. A fixed region, which is provided continuously with an end of the expansion regions in an expanding direction thereof, is not displaced according to the expansion or contraction of the expansion regions. A movable region, which is provided continuously with the other end of the expansion regions in the expanding direction thereof, is displaced according to the expansion or contraction of the expansion region. A at least one hinge portion, which is formed between the movable region and the fixed region or between the movable region and the expansion region, displaces the movable region smoothly in a moving plane of the head.

摘要： A rotating support apparatus in a disk storage device is provided with a stationary shaft, ball bearings rotatably fitted on the stationary shaft, a rotatable member rotatably supported by and on the ball bearings, and buffer rings 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 of the outer inner surfaces thereof, with the rotatable member or outer races of the ball bearings, and at one point of the inner or outer surface thereof, with the associated ball bearing or the inner surface of the hub, respectively.

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.
