    摘要: A rotational member and a stationary member included in a spindle motor provided with air bearings are electrically connected while the bearing is rotating, and abrasion of the rotational member and the stationary member at stages of starting and stopping and damaging the rotational member and the stationary member by external shocks that may be exerted thereon during transportation and handling are avoided. In one embodiment, a sleeve is formed integrally with a motor base. The sleeve has an inside surface serving as a radial-bearing surface that forms a radial bearing together with the outside surface of a rotational shaft, and a thrust-bearing surface that forms thrust bearing together with a thrust plate attached to the rotational shaft. The radial-bearing surface of the sleeve is provided with a recess (groove) for holding lubricating oil while the rotational shaft is rotating. A gap not forming a bearing is formed between the circumference of the thrust plate and the inside surface of the sleeve to hold the lubricating oil while the rotational shaft is rotating.

    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.

    摘要: Embodiments of the invention provide a magnetic disk drive that allows members to be mounted onto a base simply and accurately. In one embodiment, a magnetic disk drive comprises: a base; a disk assembly including at least one magnetic disk and mounted rotatably on the base; and an actuator assembly including at least one actuator having a magnetic head and mounted swingably on the base. The base is formed with a guide. The guide functions to guide, when a member to be disposed on the base is to be mounted, the member from a corresponding initial placement position of the member on the base to a target position, at which the member is to be disposed. Further, the guide includes a positioning portion, against which the member abuts at the corresponding target position.

    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.
