摘要： A magnetic disk unit comprising a one-piece carriage structure having a small thermal off-tracking amount, with the carriage structure including a rotary shaft; guide arms integrally supported on a guide-arm retainer at their proximal ends and extending independently and parallely; bearing retainers formed on both ends of the guide-arm retainer; and bearings fixed on the bearing retainers rotatably connecting the guide-arm retainer to the rotary shaft. A center line in a direction of thickness of the outermost guide arm is located outside of that of the bearing in a direction of height thereof, and a concave portion is continuously formed on the bearing retainer. Thermal coefficients of expansion of the guide arms and the guide-arm retainer are substantially equal, with the carriage structure being fashioned of an alloy mainly containing Al and Si, eutectic crystal Si particles in the guide arm and/or the guide-arm retainer. The average value of the longest eutectic crystal Si particles therein is 1.6 .mu.m or less or the number of the eutectic crystal Si particles if 5.0 or more per 100 .mu.m.sup.2. In the carriage of manufacturing the carriage of the carriage structure is heated for five to fifteen hours at a temperature of 300.degree. to 500.degree. C. after die casting.

摘要： An actuator mechanism for positioning magnetic heads includes arms that support a magnetic recording/reproducing head at one end thereof. Each of the arms is mounted about a shaft and supported for rotation. A coil support member is attached to the end of the arms opposite the head, and is made of a molded resin that integrally covers a voice coil motor used for causing the swinging movement of the arms. The molded resin of the coil support member is a synthetic resin mixed with a powered metal having a known specific gravity and thermal expansion coefficient. Thus, the weight of the synthetic resin can be adjusted to balance a portion including the magnetic heads and the arms with the coil support member in relation to the shaft. Additionally, the thermal expansion coefficient of the coil support member is selected to be substantially equal to that of the arms and the coil so that these components expand and contract to the same degree with variations in temperature to prevent deformation or cracks from occurring in the coil support member.

摘要： A disk array apparatus using an SAS can transfer data without lowering a transfer efficiency of data even if rates of a plurality of physical links connected to a controller and storage device are different. A plurality of HDDs are connected to a controller through an expander. Data are transferred from the controller to the expander and then to HDD. In this connection, the controller and the expander transfers a set of transfer data in a plurality of the HDD-side physical links. The controller-side physical link integrates the transfer data, and multiplexes them to transfer. A plurality of HDDs-side physical links separates the transfer data to transfer in parallel.

摘要： In the case of adding an arbitrary hard disk drive, the hard disk drive is operated in a specific operation mode suited for that hard disk drive. As triggered by the attachment of a hard disk drive to a disk adapter, a processor operates the hard disk drive in a predetermined operation mode based on predetermined parameter information that has been prepared in advance. The hard disk drive stores, in advance, particular parameter information including information about the specific operation mode suited for operation. The processor reads the particular parameter information from the hard disk drive in the predetermined operation mode and operates the hard disk drive in the specific operation mode based on the particular parameter information.
