摘要： A load beam is provided with a base plate and a slider. A magnetic head apparatus is fixed to a head arm via a base plate. In a mechanism or structure for supporting such a magnetic head supporting mechanism, an elastically deformable portion is provided between the base plate and the load beam. Thus, a floating structure that allows the load beam to swing is formed about the elastically deformable portion. In addition, a weight of the load beam is balanced with respect to the elastically deformable portion. Furthermore, a contact portion for applying pressure to the load beam is provided on the head arm so that a pressing load to a recording medium would be set by an amount of rotation of the load beam caused by the pressure applied by the contact portion.

Portions of the flexure (30) corresponding to both of the sides of this protrusion (28) are constituted by elastic hinge portions, each having a necked shape. A pair of thin-film piezoelectric elements (40a, 40b) are bonded to the flexure (30) as displacement members. In a tracking compensation operation of the head, forces are exerted on the slider supporting member (32) through the elastic hinge portion by extending and contracting operations of the pair of thin-film piezoelectric elements so that the slider (50) is allowed to pivot around the protrusion (28) of the load beam serving as the center of pivotal movements, together with the slider supporting member (32).

摘要： A head supporting device comprises a support arm (2) 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 (10) 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 (4) 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.

摘要： Disclosed is a spindle motor and a disk drive unit equipped with the same, having advantages of preventing hard collision between a disk and a signal conversion element due to lifting of rotating components, and avoiding the signal conversion element and swing means for positioning the signal conversion element from being damaged irreparably. Specifically, spindle motor 13 comprises rotor unit 5, stator 11, stator-side bearing member 6 in engagement with rotor-side bearing member 3 to form a shaft rotating type fluid bearing, and chassis 8. Rotor hub 2 has hollow cylinder portion 2a near central axis 1 of rotation, and cylindrical portion 7b of support column 7 secured to chassis 8 is positioned inside the hollow space of cylinder portion 2a without being in contact thereto. Cover 18 is placed with a bottom side of abutment portion 18b kept in abutment upon an upper end of cylindrical portion 7b of support column 7 with a predetermined small clearance provided between upper end 2c of rotor hub 2 and the bottom side of abutment portion 18b.
