According to one embodiment, a disk device includes a recording medium, a magnetic head, a ramp, and an actuator. The recording medium has a recording surface and is rotatable around a first rotation axis. The actuator includes a first portion extending so as to be separated from a second rotation axis and separated from the recording surface as the distance from the second rotation axis increases, holds the magnetic head, and is rotatable around the second rotation axis. A first support is provided on the ramp, extends around the second rotation axis, and can support the first portion so that the magnetic head is separated from the recording surface. A second support is provided on the ramp, is located between the first rotation axis and the first support, is separated from the second rotation axis farther than the first support, and can support the first portion.

According to an embodiment, a manufacturing method of a disk drive suspension comprises determining a first position on the outrigger at which a bent portion is to be formed by irradiating a first laser beam, calculating predicted values of pitch and roll angles of a tongue in a case where the bent portion is formed at the first position, determining a second position on the outrigger to which a second laser beam is to be irradiated to make the predicted values approximate to predetermined target values, and irradiating the first laser beam to the first position to form the bent portion, and the second laser beam to the second position.

A disk drive suspension according to an embodiment comprises a load beam comprising a dimple, and a flexure overlaid on the load beam. The load beam and the flexure are fixed by a first fixing portion and a second fixing portion closer to a distal end of the load beam than the first fixing portion. The flexure comprises a tongue opposed to the dimple, and an outrigger connected to the tongue. The outrigger is bent in a thickness direction of the load beam at a bent portion located between the dimple and the first fixing portion in a length direction of the load beam.

A flexure is described, which includes conductive traces extending from a proximal end of the flexure to a distal end of the flexure. The flexure also includes a plurality of outer gimbal struts configured to define an opening at the proximal end of the flexure. The flexure also includes an oblong feature extending into the opening, the oblong feature defines an aperture. The conductive traces include a first semi-circular conductive trace portion overlapping a first section of the oblong feature at a proximal end of the aperture extending to a distal end of the aperture. The conductive traces include a second semi-circular conductive trace portion overlapping a second section of the oblong feature at a proximal end of the aperture extending to the distal end of the aperture. The first and second semi-circular conductive trace portions define the aperture.

A data storage device with at least one data storage disc and a head stack assembly. The head stack assembly includes an actuator mechanism and at least one recording head supported by a suspension assembly. The suspension assembly includes a load beam and an actuator arm and at least one actuator is disposed on at least one surface of the load beam or the actuator arm. The at least one actuator is configured to deflect the at least one recording head in a vertical direction relative to the recordable surface of the storage disc.

A baseplate for a disk drive suspension is provided. The baseplate includes a receiving space at a distal end configured to mate with a spring of a load beam. The receiving space partially extends a length of the baseplate. The baseplate also includes a swage hub at a proximal end and an indented surface surrounding the swage hub. The proximal end is opposite the distal end. The indented surface is at least partially defined by a baseplate support section.

According to one embodiment, a disk device includes a magnetic disk, a load beam, a flexure, a head unit, and a first restrictor. The load beam has a first face facing the magnetic disk. The flexure is attached to the first face. The head unit includes: a magnetic head attached to the flexure, configured to read and write information from and to the magnetic disk; and a heat-assister attached to the magnetic head, configured to heat the magnetic disk. The first restrictor is included in the head unit, configured to come in contact with at least one of the load beam and the flexure along with movement of the magnetic head away from the first face by a first distance.

A hard disk drive includes multiple actuator assemblies, each of which includes a head-stack assembly (HSA) including an end-arm to which a single head-gimbal assembly (HGA) is coupled, where this end-arm is configured with a notch along one side and a triangular or quadrilateral-shaped through-hole at a root-side of the end-arm, and where the HSA further includes a plurality of other end- and inner-arms to each of which two HGAs are coupled and none of which have a through-hole near their root. The single-HGA end-arm may be further configured with an outer damper having a through-hole coincident with the end-arm through-hole, such that the through-hole of the end-arm is not covered by this damper, and an inner damper having no through-hole, such that the through-hole of the end-arm is covered by this damper. Gains are thereby better matched across all HGAs for problematic arm and system modes.

A hard disk drive suspension assembly includes a pad base layer, a pad-end fixing layer, and a plurality of electrical pads each comprising a conductive layer on the pad base layer, where the base layer extends to the fixing layer, to which a distal end of the base layer is fixed. This configuration inhibits the delamination or deformation of the end edge of each pad. An additional cover layer may be implemented to cover the distal end of the conductive layer(s), further inhibiting deformation of the pads. These techniques are especially relevant with narrow, high-density, small pitch electrical pads.

A method of manufacturing a disk drive suspension includes applying an adhesive to an actuator mounting portion, increasing viscosity of the adhesive by emitting light to the adhesive applied to the actuator mounting portion, arranging the piezoelectric element on the adhesive having the increased viscosity, detecting a height of the piezoelectric element arranged on the actuator mounting portion, and correcting an irradiation condition of the light in accordance with the detected height of the piezoelectric element.
