摘要： A linear actuator assembly for linearly the reciprocatingly moving magnetic heads in a magnetic disk storage apparatus. This linear actuator has a carriage for supporting magnetic heads, and a voice coil for moving the carriage. The sectional configurations of the carriage and the voice coil are equalized, thereby enabling the transmission of the driving force from the voice coil to the carriage without any eccentricity. This linear actuator also has a vibration absorbing mechanism for absorbing vibrations caused when the linear actuator operates, and a runaway prevention mechanism for limiting the movable range of the carriage.

摘要： A disc memory device has a disc memory assembly comprised of a disc, head and a head actuator. The assembly is movably mounted to a base of the disc memory device such that it can move in the same direction as an operative direction of the head actuator, thereby ensuring that vibrations generated in response to acceleration/deceleration of the actuator can be absorbed by the whole of the disc memory assembly.

摘要： An axial force exerting in the axial direction of a rotary actuator is uniformly applied to a plurality of axially arranged ball bearings of a bearing set to hold inner and outer rings of each ball bearing in optimum position, thereby heightening the rigidity of the bearing set. A waved washer is interposed between the ball bearings and distributes the axial force so as to axially slide the ball bearings. While being slidden to the optimum positions, the ball bearings are bonded for fixing.

摘要： A magnetic disk system utilizes both of voice coil motor and a piezoelectric element provided on a head supporting arm to precisely position a head to a predetermined position on a disk. The piezoelectric element is built in the distal end portion of the head supporting arm and is restricted in respect of its movement by a resilient mechanism which has low rigidity in the driving direction of the piezoelectric element and high rigidity in the other directions. The resilient mechanism is formed by pairs of doubled parallel leaf springs so arranged that each pair is disposed on either side of the piezoelectric element.

摘要： In a magnetic disk apparatus, a head positioning signal is written on a magnetic disk, the written positioning signal is read out, the read positioning signal is demodulated to produce a position signal, and a data write/read head is positioned to a predetermined track in responses to the produced position signal. A head positioning signal is written into write tracks adjacent to each other along a radial direction of the magnetic head, the positioning signal is read out by tracing a read track bridging the write tracks, and a positioning error of the head positioning signal is generated from a shift of the read positioning signal with respect to the read track. Furthermore, the position signal is over-written by actuating the write head in the radial direction according to the positioning error.

摘要： A spindle assembly for magnetic disks of both-end support type has a hub for fixing the disks, a shaft to which the hub is fixed, a pair of bearings which are spaced in vertical or horizontal direction, a pre-loading spring for pre-loading one of the bearings, and a housing composed of housing parts which accommodates the hub, shaft, bearings and the pre-loading spring. The spindle assembly further has an axial reference surface formed on the hub at a right angle with respect to the shaft, and another axial reference surface formed on one of the housing parts at a right angle with respect to the vertical portion of the bearing associated with the one of the housing parts. When the shaft is mounted in the one of the housing parts with the hub and the pre-loading spring fitted therearound, the hub is axially urged by the spring such that the axial reference surface thereon is brought into abutment with the axial reference surface on the one of the housing parts. As a result, the axis of the spindle assembly is determined by the abutment between the reference surfaces and by the bearing in the one of the housing parts. The bearing in the other of the housing parts is axially aligned with the thus determined axis of the spindle assembly.

摘要： A magnetic head loading apparatus serves to load a magnetic head on the surface of a disc-shaped magnetic recording medium rotating continuously so as to perform the recording and reproduction of data. The magnetic head is shifted from unload to load position by means of a drive means. In order to prevent damage to the recording medium due to the collision of the magnetic head with the recording medium, the drive means is so controlled as to cause the magnetic head to decellerate as the magnetic head approaches the load position.
