摘要： A hydrodynamic bearing rotary device which can reduce rotation friction, and recording and reproducing apparatus including the same is provided. In the hydrodynamic bearing rotary device, such as hard disc devices, a rotary shaft having a hub on one end is provided in a bearing of a sleeve so as to be rotatable. Thrust hydrodynamic grooves are provided on the other end surface of the rotary shaft, to form a thrust bearing with the thrust plate. A communication path is provided in the sleeve. The second gap between the hub and the sleeve end surface is used as a flow channel and is connected to the communication path. In this way, the rotation friction torque of the thrust bearing can be made sufficiently small, and internal pressure in bonded portions of the rotary shaft or the bottom plate can be suppressed. Thus, the oil can be prevented from oozing out from a small space of the bonded surfaces. Furthermore, the hydrodynamic bearing can be made thin. These effects can be combined to realize an optimal hydrodynamic bearing rotary device.

摘要： In a hydrodynamic bearing device in which a radial bearing face having a dynamic pressure generating groove on a shaft or an inner periphery of a sleeve is provided and a clearance between the shaft and the sleeve is filled with lubricant, an annular depression is provided on one end face of the sleeve adjacent to a rotor hub and a cover plate for covering the depression is attached to the sleeve so as to define a reservoir for the lubricant or air for the purpose of preventing such a risk that absence of an oil film occurs in clearances of a bearing of the hydrodynamic bearing device due to outflow of oil upon forcing of the oil by air received into the bearing. A step portion is provided on the other end face of the sleeve such that the step portion and the reservoir are communicated with each other by a communication hole. During operation of the hydrodynamic bearing device, air in the hydrodynamic bearing device reaches the reservoir via the communication hole so as to be discharged from the reservoir.

摘要： To prevent air from being trapped inside a bearing and causing the bearing to have oil film rupture and NRRO to deteriorate. In a hydrodynamic bearing, a first lubricant reservoir is provided in a gap between a lower surface of a hub and a sleeve, and a second lubricant reservoir is provided in a gap between an outer peripheral surface of the sleeve and an inner peripheral surface of the hub or an inner peripheral surface of a stopper member fixed to the hub. If air enters inside such a hydrodynamic bearing, the air has to be discharged. For this purpose, the relationship in widths of the radial bearing gap, the maximum gap of the first lubricant reservoir under the lower surface of the hub and the maximum gap of the second lubricant reservoir on the sleeve outer peripheral surface, or the relationship in magnitudes of capillary forces thereof is adjusted. The principle that air tends to move toward the portion having smaller capillary pressure is utilized to make it difficult for the air to be trapped inside the bearing and to smoothly discharge the air from a gas-liquid interface of the second lubricant reservoir.

摘要： A set of radial dynamic pressure generating grooves constitute a radial bearing, and an entire width (L) of the radial dynamic pressure generating groove is reduced. A set of thrust dynamic pressure generating grooves constituting a thrust bearing are formed so that an area where a maximal thrust dynamic pressure is generated (diameter) is increased, and a bearing angle stiffness of the thrust bearing is increased. The thrust bearing having the high bearing angle stiffness shares a moment load applied to a shaft to thereby compensate for a bearing angle stiffness of the radial bearing whose bearing stiffness is small because an entire width of the radial bearing is small. Thus, a thin-shaped hydrodynamic bearing capable of withstanding a large moment load is obtained.

摘要： A capacity layer is formed of non-doped polysilicon. Unlike capacity layers formed of an oxide film, generation of seams and the like can be suppressed and thereby a stable capacity layer can be formed. Moreover, polysilicon used as a capacity layer may be doped polysilicon, and an oxide film formed on the surface of the polysilicon also serves as a capacity film. Thus, provision of an insulated gate device featuring low capacity is made possible.
