摘要： Embodiments of the present invention provide a magnetic disk unit capable of attaining miniaturization, lower cost, lighter weight, lower profile, and higher density. According to one embodiment, only a carriage and a spindle motor among respective constituent components of a hard disk drive (HDD) are securely attached to a support plate made of a hard metal material higher in rigidity than a shroud. All the constituent components of the HDD, except the carriage, and the spindle motor, (a voice coil motor, a ramp, a latch lever, an HDD connector and so forth), that is, the respective constituent components of the HDD, of which assembling precision, rigidity, and so forth are not required, are attached to the shroud small in wall-thickness, and lighter in weight, formed of a resin material such as plastics and so forth.

摘要： Embodiments of the invention prevent trouble caused by an increase in viscosity of grease generated when a ball bearing operates at a low temperature, and fretting that an inner ring and/or an outer ring comes in contact with balls to produce wear when vibration is applied thereto. In one embodiment, a ball bearing is configured such that a plurality of balls are arranged between an outer ring and an inner ring. Grease is filled between the balls, the inner ring and the outer ring. A holder is provided with a spring plate, and an extreme end thereof is always in contact with the balls. The spring plate is formed of a sufficiently softer material than the balls so as not to damage the balls. The mounted direction is one along the direction in which the balls are desired to be rotated. Appropriate spring pressurization can be applied to the balls at an angle defined by the holder and the spring plate in the root at which the holder is attached to the spring plate.

摘要： Embodiments of the present invention help to effectively suppress vibration of the disk in a Hard Disk Drive (HDD) with low density gas sealed therein, and securely prevent leakage of the low density gas from the base. In an embodiment, helium gas is sealed in a hermetically sealed enclosure of an HDD, and a shroud is formed integrally with a base. In manufacturing the base, a magnetic disk facing surface of the shroud is shaped by cutting after die-casting. This accomplishes a small and precise size of the gap between the magnetic disk facing surface and the circumferential edge of the disk. Cutting the shroud formed independently from the exterior walls, which ensure the hermeticity with the shroud, suppresses the vibration of the magnetic disk and eliminates the necessity of cutting of the inner surfaces of the exterior walls for the purpose of suppression of the vibration to reduce the risk of helium leakage.
摘要翻译：本发明的实施例有助于有效地抑制密封在其中的低密度气体的硬盘驱动器（HDD）中的盘的振动，并且可靠地防止低密度气体从基座泄漏。在一个实施例中，氦气密封在HDD的气密密封的外壳中，并且护罩与基座一体地形成。在制造基座时，通过在压铸之后的切割来成形护罩的面向磁盘的表面。这实现了磁盘对向表面和盘的圆周边缘之间的间隙的小而精确的尺寸。切割独立于外壁形成的护罩，其确保与护罩的气密性，抑制磁盘的振动，并且消除了为了抑制振动的目的而切割外壁的内表面的必要性，以减少氦气泄漏的危险。
