摘要： Embodiments of the invention reduce the height of a ramp to provide a thin data storage device that is capable of inhibiting the deterioration of the dynamic characteristics at the time of loading/unloading. In one embodiment, a data storage device includes a head that accesses a recording region of a recording disk; a ramp that is positioned circumferentially apart from an outermost end of the recording disk to unload the head from a surface of the recording disk; and an actuator that includes a load beam for supporting the head and moves the head. The load beam includes a tab that is extended from a leading end section of the load beam, beyond the head support section of the load beam, and toward the recording disk, and slides over a ramp surface.

摘要： Embodiments of the invention permit a magnet-based actuator lock mechanism to operate smoothly in a magnetic disk drive that uses a base made of a magnetic material. In one embodiment, the base to be used is made of a magnetic material. The actuator lock mechanism includes a rotatable arm that retains a magnet. A magnetic attraction force, which is oriented toward the base as indicated by an arrow, is generated in the magnet. The base is provided with a cut to reduce the attraction force. The cut is covered with a sealing material to maintain internal airtightness. The actuator lock mechanism may be, for instance, an eddy-current latch, inertia latch, or magnetic latch.

摘要： To attach a suspension assembly to the actuator, the suspension is connected to a mount plate. The inner diameter of the swaging boss in this mount plate differs depending upon if it is on a lower or upper suspension of an actuator arm. After setting only the mount plates with bosses of a larger inner diameter and performing the first swage, the mount plates of the smaller inner diameter are set and a second swage is performed in a different direction. Even when performing this bidirectional swage, a boss caulked with the first swage is subjected to no deformation after a later swage and therefore a stable swage is possible.

摘要： A mechanism is provided for restraining and releasing an actuator suspension assembly in a magnetic disk device which is in a retracted position. In a magnetic disk device, according to one embodiment, a magnetic disk 4a is formed of an electrically conductive material and there is disposed a latch member 50 which holds an eddy-current magnet at one end thereof and is provided with a latching portion at an opposite end thereof. An actuator suspension assembly 8 lies in a retracted position and is restrained at a frame engaging portion 23 thereof by means of the latch member. The eddy current magnet is disposed in such a manner that a magnetic pole thereof is opposed to a surface of the magnetic disk at a position close to the disk surface. When the magnetic disk is rotated, an eddy-current is generated and a force is exerted on the eddy-current magnet, so that the latch member turns and releases the actuator suspension assembly.

摘要： Embodiments of the present invention effectively control, by a simple structure, floating of a rotor of a fluid dynamic bearing motor mounted in a hard disk drive. In one embodiment, a base is formed of a magnetic material. The attractive force caused by the magnetic force acts between a bottom of the base and a magnet unit that is constituted of a rotor magnet and a back yoke. This makes it possible to attract a rotor to the base against the buoyant force produced by a thrust bearing, and thereby to effectively control the rotation of the rotor. On the bottom of the base, at a position facing the magnet unit, a convex part protruding from the inner surface of the base is formed in a ring-shape. Adjusting the height, or the width, of the convex part makes it possible to control the magnetic back pressure applied to the rotor.

摘要： The present invention provides a depopulation version hard disk drive apparatus that has a reduced number of magnetic heads and suspension arms from a standard hard disk drive apparatus, wherein the magnetic head can still be properly controlled during a loading state. The hard disk drive apparatus includes a ramp which interfaces with the suspension arm when loading and unloading the arm. An angle of a second slope surface 61c of the ramp in the depopulation version hard disk drive is set larger than that of the corresponding slope surface of the ramp 6 the a standard version hard disk drive.
