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： 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.
