摘要： A head support device is thin and assures excellent flexibility and shock resistance while applying a sufficient load to a head. A disk drive uses the head support device. The head support device comprises a support arm, a head disposed at one end of the support arm, which is mounted on a head slider so as to be opposed to a recording medium, an elastic member such as a plate spring which provides the support arm an activating force in a direction perpendicular to the recording medium when the support arm comes to a rotational center in vertical rotation against the recording medium, and a holder connected to the elastic member. When an external impact force is applied to the head slider, with a distance from an action point of load that activates the head slider toward the recording medium to an immovable point in the rotation of the head slider in a direction of pitch being Lo, and a length of head slider in a direction of air flow being Ls, then 0.5

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 head suspension assembly includes (a) a slider having a head for recording into/reproducing from a record medium, mounted thereon, (b) a load beam having (i) the slider disposed via a flexure at one end, and (ii) a leaf-spring-like resilient member integrally formed therewith in the vicinity of the other end along the longitudinal centerline thereof, and (c) a carriage having a pair of pivots in contact with the load beam. The distal end of the resilient member is joined to the carriage and the resilient member has an opening (hole) in the center thereof. Because the stress occurring in the leaf-spring-like resilient member that is provided in the load beam of the head suspension assembly is reduced, the resilient member exerts sufficient urging force to the head and has high flexibility. This structure can provide a highly shock-resistant and thin head suspension assembly.

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 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 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.
