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： An opening-closing device includes a fixed gear of a fixed body, a conversion gear engaged with the fixed gear, a movable gear of a movable body, and a relay gear engaged with the conversion gear and with the movable gear, all of which are attached to a locking plate. The movable body can be held at a predetermined angle with respect to the fixed body by making an engaging portion in the locking plate is contacted with a locking portion in the fixed body and by making the conversion gear move to another position when the movable body is opened at the predetermined angle with respect to the fixed body. Moving the conversion gear to another position makes it possible to perform opening and closing operations in a greater angle. Thus, the opening-closing device can have a simple structure and perform a variety of opening and closing operations.

摘要： A head suspension assembly includes a head, a load beam carrying the head at one end, a resilient member joining the load beam and a carriage, and a pivot bearing provided between the load beam and the carriage and structured so that the load beam is movable in a direction perpendicular to a record medium so that the load beam rocks. The head suspension assembly is structured so that the resilient member has narrow sections for reducing the width of the resilient member to a width smaller than that of both ends of the resilient member that are symmetrical with respect to a centerline of the resilient member. The distal end of the resilient member is joined to the carriage and the resilient member has an opening (hole) in the center thereof. This structure provides a highly shock-resistant and thin head suspension assembly.

摘要： A disk apparatus includes (a) an actuator having a head supporting arm with a tab formed on the arm and a voice coil fixed to the arm, which arm is rotatable on a horizontal rotary shaft as well as on a vertical rotary shaft, (b) a voice coil motor having an upper yoke with a magnet fixed to the upper yoke and a lower yoke sandwiching and confronting the voice coil, and (c) a ramp section guiding and holding the tab at a refuge place. When the actuator at the refuge place starts loading with a starter command, a pulsed driving current is applied to the voice coil temporarily for urging the tab against a tab-holding plane of the ramp section, thereby making use of repulsion force generated on the actuator, so that the tab can leave the refuge place efficiently for carrying out the loading operation.

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： 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.
