摘要： Embodiments of the invention provide a magnetic disk drive promoting even higher densities, greater capacities, and further reduction in size, while relaxing component accuracy requirements. In one embodiment, the magnetic disk drive includes a magnetic disk receiving member and a magnetic disk holding member, a magnetic disk being rotatably held with the magnetic disk clamped therebetween. The receiving member makes a line contact with a surface of the magnetic disk on a circumference of a circle formed around a rotational axis of the magnetic disk.

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.
摘要翻译：本发明的实施例防止了当球轴承在低温下运行时产生的润滑脂的粘度增加所引起的麻烦，并且使得内圈和/或外圈与球接触以产生磨损以产生振动时的磨损。在一个实施例中，球轴承构造成使得多个球布置在外圈和内圈之间。润滑脂填充在球，内圈和外圈之间。保持器设置有弹簧板，并且其末端总是与球接触。弹簧板由比球更柔软的材料形成，以免损坏球。安装方向是沿着滚珠希望旋转的方向的方向。适当的弹簧加压可以由保持器和保持器附接到弹簧板的根部中的弹簧板限定的角度施加到球。

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： A magnetic disk device wherein a member having and suspension thereof a natural frequency similar to that of a head is disposed on an opposite surface of a head arm having one head mounted thereto via a suspension. The outermost shape (profile when the member is projected in a direction perpendicular to the surface of the magnetic disk) of the member having the natural frequency equal to that of the head and suspension thereof is similar to that of the head and the suspension or does not swell out from the profile of the head and the suspension. The member having the natural frequency similar to that of the head is provided to the head arm by the same device as that of the head.
