    摘要: A magnetic disk apparatus includes a magnetic disk, a magnetic head which performs information recording and reproducing for the magnetic disk, a load spring for supporting the magnetic head, a head arm for fixing the load spring, a housing for housing these components, a shaft which fixes the head arm, bearings for supporting the shaft rotatably on the housing, and a motor which is coupled to the shaft. The motor comprises a motor cover, a permanent magnet which is divided into a plurality of segments and fixed on the shaft, and a coil which is fixed on the interior surface of the motor cover by being spaced with a certain gap from the permanent magnet. The shaft is included with a counter weight so as to complement the weight of the head arm, load spring and magnetic head. The coil has linear conductor sections parallel to the shaft, with the total number of linear sections being set equal to the total number of segments of permanent magnet.

    摘要: A magnetic head disk apparatus has a housing with one thicknesswise end providing the front side and the other thicknesswise end providing the rear side of the apparatus. The apparatus further has a plurality of head disk assemblies each including at least one combination of a magnetic head and a magnetic disk. The head disk assemblies are arranged in a plurality of rows not only in heightwise and breadthwise directions but also in the thicknesswise direction of the housing. With this arrangement, it is possible to accommodate a multiplicity of head disk assemblies with a high space factor in the housing.

    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 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: An electronic apparatus, such as a disk apparatus, has a plurality of electronic units such as magnetic head-disk units and at least one power source unit for supplying power to the electronic units. The arrangement of the electronic apparatus is such that, on a frame of the apparatus, the plurality of electronic units are vertically arranged in such a manner as to form a first arrangement system, while the at least one power source unit is arranged in such a manner as to form a second arrangement system above the first arrangement system. The apparatus has an air flow passage for causing cooling air to flow from a lower portion of the electronic apparatus to the inside thereof, pass through the first arrangement system, thereby pass through the second arrangement system, and then be discharged to the outside of the apparatus. This arrangement enables cooling air to flow in a simplified manner, which in turn enhances the cooling efficiency, and also enables electrically connecting cables to be arranged in a simple wiring system.

    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.
