Abstract: A disk drive including a tray and an opener. The tray includes a disk cartridge mounted thereon and is loaded into and unloaded from a main body. The opener is installed in the main body and elastically contacts a guide formed on the tray. The opener includes a second gear and a first protrusion. The second gear rotates a rotating wheel when in contact with a first gear. The first protrusion formed on a first end of the second gear temporarily rotates the rotating wheel so that the first and second gears can mesh. The guide has a first cam that moves the opener such that the first protrusion does not interfere with the latch when the tray is loaded/unloaded.

Abstract: A disc cartridge includes a case accommodating a disc and having an aperture hole formed on a first surface of the case so that a recording/reproducing apparatus access a recording surface of the disc, and an open hole formed on a second surface to be open to an outside of the case, a shutter opening/shutting the aperture hole and installed in the case, a disc holder installed at a side defining the open hole to move up and down and covering a gap between an outer circumference of the disc and an inner surface of the side defining the open hole when the disc holder descends, and a shutter driving mechanism moving the shutter so that the aperture hole is open/shut. Thus, a passage through which dust is introduced toward an information area of the disc, and a gap formed at an outer circumference are blocked by the disc holder so that a possibility of contamination by dust can be reduced.

Abstract: A fluid bearing apparatus includes a thrust load supporting portion formed between an external side surface of a fixing shaft and an internal side wall of an opening in a bushing; the surface and wall facing each other. The thrust load supporting portion includes a ball inserting groove formed on the external side surface of the fixing shaft and/or the internal side wall of the bushing and a ball inserted into the ball inserting groove. The upper end portion of the shaft is lower than the upper end portion of the bushing. Since the thrust load is supported by the balls instead of by the upper end portion of the fixing shaft, it is possible to prevent movement of the fixing shaft when the fluid bearing apparatus starts to rotate. The frictional resistance of the upper end portion of the fixing shaft can be reduced when the fluid bearing apparatus starts to rotate and stops its rotation.
Abstract translation: 流体轴承装置包括形成在固定轴的外侧表面和衬套中的开口的内侧壁之间的推力负载支撑部分; 表面和墙壁彼此面对。 推力负载支撑部分包括形成在固定轴的外侧表面上和/或衬套的内侧壁上的球插入槽和插入到球插入槽中的球。 轴的上端部比衬套的上端部低。 由于推力负载由球代替由固定轴的上端部支撑，因此当流体轴承装置开始旋转时可以防止固定轴的移动。 当流体轴承装置开始旋转并停止其旋转时，可以减小固定轴的上端部的摩擦阻力。
