    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: A pad for controlling the state of contact or flying of a slider with or to an information-recording medium and a probe for exciting near-field light having a small spot size are mounted on the slider and the pad is near to the probe. Semiconductor laser light focused by an objective lens is converted into near-field light having a small spot size near the top of the probe for exciting near-field light. The slider travels at a height of several tens nm to a recording medium substrate and information is recorded or read out on or from the information-recording medium formed on the recording medium substrate.

    摘要: A disk drive configured with micro-actuator interconnect conditioning. The disk drive includes a disk, a head, an actuator, a piezoelectric element, a hardened conductive adhesive, a voltage-supply circuit, and a controller. The head is configured to access the disk. The actuator includes a suspension supporting the head, and an arm supporting the suspension. The piezoelectric element is disposed on the suspension, is electrically connected to a first drive line and a second drive line, and is configured to change the position of the head. The hardened conductive adhesive is electrically connected to at least one connecting part of the piezoelectric element and the first drive line. The voltage-supply circuit is configured to supply a voltage to the piezoelectric element. The controller is configured to control a voltage-control circuit each time a designated process is executed, and to apply a voltage to the piezoelectric element with a prescribed maximum absolute value.
