    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： A disk drive configured with micro-actuator interconnect conditioning. The disk drive includes a disk, a head, an actuator, a piezoelectric element, a hardened conductive adhesive, a voltage-supply circuit, and a controller. The head is configured to access the disk. The actuator includes a suspension supporting the head, and an arm supporting the suspension. The piezoelectric element is disposed on the suspension, is electrically connected to a first drive line and a second drive line, and is configured to change the position of the head. The hardened conductive adhesive is electrically connected to at least one connecting part of the piezoelectric element and the first drive line. The voltage-supply circuit is configured to supply a voltage to the piezoelectric element. The controller is configured to control a voltage-control circuit each time a designated process is executed, and to apply a voltage to the piezoelectric element with a prescribed maximum absolute value.
