摘要： A disk locating actuator of a disk apparatus has a carrier member carrying a head and a curved flexible printed circuit fixed at its one end to the carrier member and at its other end to a base. Angles at which the flexible printed circuit is fixed are suitably determined so as to diminish any dynamic reacting force produced by vibration of the flexible printed circuit, thus ensuring high degree of head locating precision.

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： The transfer assembly includes a belt, a transfer device, a contact-and-separation device including a retainer, and a first vibration absorber. The transfer device contacts an image bearer via the belt to form a transfer nip portion between the image bearer and the belt and to transfer the toner image onto one of a surface of the belt and a recording medium carried on the surface of the belt. The contact-and-separation device moves the transfer device to contact and separate from the image bearer. The retainer is pivotally supported by a swingable shaft and movable in a first direction in which the transfer device approaches the image bearer and in a second direction opposite to the first direction in which the transfer device separates from the image bearer, to hold the transfer device. The first vibration absorber absorbs vibration transmitted from the swingable shaft to the transfer device via the retainer.

摘要： Return channels 45a, 45b, 45c, and 50 are formed to guide air flowing through a clearance between a magnetic disk (11) and a shroud (41) so that the air flows behind a voice coil motor, bypasses a loading/unloading mechanism (31) and flows toward a region on the lower side of the loading/unloading mechanism 31 with respect to the rotating direction of the magnetic disk (11). Thus, production of turbulent flow in the vicinity of the loading/unloading mechanism 31 is controlled. Fluttering of the magnetic disk (11) can be controlled by placing a filter 60 in one of the return channels.
