摘要： A head support device that is resistant to shock due to external impact, a disk device including the head support device, and a portable electronic device including the disk device are disclosed. In the head support device, a head support arm on which a head slider with a head is disposed through a flexible and elastic gimbal mechanism is formed rotatably about a rotary shaft as a horizontal rotating axis in parallel with a disk surface. The head support arm is formed such that it pivots, about a straight line drawn between apexes of a pair of pivots as a vertical pivot axis, vertically (generally perpendicularly) with respect to the disk surface. A gravity center position of a total mass of members, other than the head slider, pivoting about the vertical pivot axis is positioned near the vertical pivot axis.

摘要： A disk drive apparatus having a head support device with high impact resistance which ensures L/UL operation and CSS operation. The disk drive apparatus includes a supporting arm rotating about a bearing in a direction perpendicular to a recording face of a recording medium; and a ramp provided at any position between the bearing and a head of the supporting arm. The ramp vertically moves the supporting arm while the supporting arm rotates or linearly moves in a radial direction of the magnetic recording medium.

摘要： A head supporting device with a loading/unloading mechanism and a disk drive unit using the head supporting device. The head supporting device and a voice coil motor (VCM) make up a head actuator of the drive system. The head actuator has i) a support arm rotatable on a bearing, moving in directions along the radius of a recording medium and vertical to the surface of the medium; ii) a magnetically levitating head on a slider facing the medium; and iii) resilient member for applying force to the arm in a direction close to the medium. The VCM has a pair of yokes, a magnet, and a coil. When the head is lead to a head retracting position, the other end of the arm is pulled by the interaction of a magnetic member and the magnet at the resting position and adjacencies. This eases the load on the VCM, contributing to a compact and slim disk drive unit with toughness and rapid data-access.

摘要： To provide a disk drive system provided with an inertial latching mechanism which has high reliability and can be arranged in a thin-model disk drive system. There is provided an inertial arm (7) engaging an actuator (22) when a head arm (25) is in or near a parking position and releasing engagement with the actuator (22) when the head arm (25) is in or near a position close to a disk (1) and energizing means for holding a position of the inertial arm (7) in a position where the engagement with the actuator (22) is released. Even if a rotational shock is externally applied when the actuator (22) remains in the parking position, moment of rotation is applied on each of the actuator (22) and inertial arm (7) in the same direction, the actuator (22) and inertial arm (7) mutually restrain their operations at an engaging part, and the oscillation of the actuator (22) to a data area can be avoided. When loading, a position of the inertial arm (7) is held by the energizing means in the position where the engagement with the actuator (22) is released so that the release of the engagement and mode of operation of the engagement between the actuator (22) and inertial arm (7) when loading/unloading can be surely achieved.

摘要： A head supporting device comprises a support arm and a head mounted to an underside surface at one end of the support arm. The support arm is disposed in a rotatable manner about a bearing unit in a radial direction of a recording medium as well as a perpendicular direction with respect to a writing surface of the recording medium, and the support arm is provided with resilient means for imposing upon itself with a thrusting force in a direction toward the recording medium. Because of this structure, a portion serving as the support arm can be formed with a material of high rigidity, the thrusting force of the resilient means upon the slider can be set freely as desired, and its resonance frequency can be increased, thereby providing the head supporting device with an extremely high resistance to shock, and high responsivity with capability of making a high speed access.
