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.

In attaching a load beam to a carriage, the swage attachment is used between the carriage and a mountplate, while the load beam is attached to the mountplate by welding and other binding means, to create a structure in which the load beam does not come into direct contact with the swage part, so that a structure is obtained in which the load beam is hardly subject to deformation or other direct influences from the swage operation. In addition, by forming the attaching plate side of the load beam to envelope a carriage, or by extending both sides of the load beam from the central portion in the longitudinal direction toward the carriage, a structure improved in the stability of load beam attachment is obtained.

The present invention provides a stacked type actuator arm assembly equipped with a structure for easily fixing lead wires between a coil and a flexible cable. A stacked type actuator arm assembly that is used in a magnetic disk storage is equipped at the coil support portion of a coil support spacer with a small hole through which lead wires and are inserted. Since the spacer is stamped from a flat sheet, a structure for holding the lead wires cannot be freely formed as in a die casting method, but formation of the small hole according to the present invention is easy. During manufacturing, after the lead wires and have been inserted through the small hole, if they are processed in the following fabrication step, there is no possibility that force will be applied to the boundary portion between a coil and the lead wire extending from a wire of the coil which would peel a wire of the coil off. In addition, in the magnetic disk storage being operated, there is no possibility that the lead wires will move and then touch other components.

A magnetic disk drive is to be provided wherein a ramp and a magnetic disk do not overlap each other and both rigidity and dynamic characteristics of a suspension are maintained. In one embodiment, a ramp and an actuator lying at a retractive position are spaced away from and do not overlap an outer peripheral end of a magnetic disk. A tab is formed centrally of a front end of a load beam and is bent in U shape. Flanges are formed along both longitudinal edges of the load beam. An aperture is formed in a front portion of the load beam. The aperture permits the tab to be machined in a desired shape. An aperture is formed behind the aperture. The aperture is used to clamp a head in a wire bonding step for the head. The apertures and are not formed in an integrally contiguous manner but are separated from each other by a bridge portion.

Embodiments of the present invention help provide a simple and inexpensive actuator mechanism for a magnetic disk drive. The actuator mechanism includes an approximately circular coil and a simple shaped magnet, and is capable of displaying adequate performance required for the magnetic disk drive. According to one embodiment, the magnetic disk drive includes an actuator mechanism which has an approximately circular coil and an approximately rectangular magnet. The long axis direction of the rectangular magnet is oriented in parallel to a straight line connecting the center of the inner circle of the circular coil in a state in which the actuator is positioned at the outermost circumference of a data area and the center of the inner circle of the circular coil in a state in which the actuator is positioned at the innermost circumference of the data area.

Embodiments in accordance with the present invention reduce the height of a head gimbal assembly (HGA) while maintaining the rigidity of a load beam. According to one embodiment of the present invention, an HGA includes a slider, a flexure, and a load beam. The load beam includes a flange formed to protrude to the opposite side to a magnetic disk at the edge of the load beam extending in the length-wise direction. The load beam has a recessed portion opened to the side opposing the magnetic disk and having an opening area larger than the area of the back surface of the slider opposing the flexure. The slider is provided in the recessed portion so that the position of the surface of the load beam is between a virtual surface including the surface of the slider opposing the magnetic disk and a virtual surface including the slider back surface.

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.

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.
