    摘要: The actuator disclosed herein comprises a coil, a magnet and a magnetism detection element. The magnet is configured to move a predetermined distance relative to the coil via a magnetic force generated when current is passed through the coil. The magnet includes a first polarization line perpendicular to the direction in which the magnet moves relative to the coil, and a second polarization line parallel to the first polarization line. The magnetism detection element is configured to detect the position of the magnet. The coil faces the first polarization line and the magnetism detection element faces the second polarization line. The length from the second polarization line to a first end of the magnet is equal to or more than 1.25 times the predetermined distance. The first end of the magnet is closer to the magnetism detection element than to the coil.

    摘要: There is provided a disk apparatus having a clamp structure, which can fix a disk in a stable manner with a simple construction. More specifically, the disk apparatus includes a hub having a disk inserting portion having a cylindrical plane in the outer part of one end and a disk receiving portion having a flat part and being pivotably supported, a head having an inner hole through which the disk inserting portion is fitted, facing toward one face of a disk, levitating and scanning above the disk and reading a signal recorded on the disk or recording a signal on the disk, the disk being held by the disk receiving portion, and a clamp unit holding the disk with the disk receiving portion. In this case, the disk receiving portion has an inclined or declined plane. Thus, the amount and direction of deformation of the disk, which is caused by clamping, are defined, and obtaining a stable amount of head levitation independently of temperature changes can prevent the occurrence of a distortion of the disk. Therefore, a decrease in head output, for example, can be prevented, and the reliability can be improved.

    摘要: A thrust dynamic pressure bearing with high inclination-resistant rigidity against axis runout and additionally low bearing loss torque is implemented. Herringbone grooves (131) having intermediate bends (132) are provided on rotating-side bearing surface (11) provided on the rotating-side bearing member. When rotating-side bearing surface (11) rotates in direction A (clockwise), lubricating oil generates dynamic pressure in an area centering on intermediate bend (132) along radially outer part (133) and radially inner part (134) of herringbone groove (131). As a result that groove width (G) of a dynamic pressure generating groove and width (L) of a land adjacent to the dynamic pressure generating groove holds G>L at an arbitrary radius (2) position, a thrust dynamic pressure bearing with high inclination-resistant rigidity and additionally low bearing loss torque is provided.
