摘要： A disk drive includes a disk drive base, and a spindle. A disk is attached to the spindle, and the disk includes a disk outer peripheral extent. An actuator is attached to the disk drive base and defines an actuator pivot axis that is substantially parallel to the spindle rotation axis. At least one actuator arm extends away from the actuator pivot axis. A head gimbal assembly (HGA) is attached to the at least one actuator arm. A first disk limiter tab protrudes from a side of the actuator towards the spindle rotation axis. The disk drive also includes a ramp that has a parking surface that is in contact with the HGA with the disk drive in a non-operational state. The first disk limiter tab extends over the disk outer peripheral extent in the non-operational state.

摘要： A disk drive includes a spindle that defines a spindle rotation axis, and a disk drive base that has a base depression bounded by a first base depression brim. A disk is attached to the spindle, and the disk includes a disk outer peripheral extent. The disk drive includes a disk limiter protrusion extending over an arc of the disk outer peripheral extent that spans no more than 20° about the spindle rotation axis. According to one aspect of the invention, a first radius that extends from the spindle rotation axis over the first base depression brim is angularly disposed no more than 25° from any second radius that extends from the spindle rotation axis to the disk limiter protrusion. According to another aspect of the invention, the disk limiter protrusion may protrude from an edge of a VCM yoke top plate towards the spindle rotation axis.

摘要： A novel disk drive head stack assembly (HSA) includes a first head gimbal assembly attached to a first actuator arm. A dummy mass is attached to a second actuator arm. The dummy mass includes a mounting plate portion defining a mounting plate width. The mounting plate portion includes first and second projections. The dummy mass also includes a neck portion defining a neck width and a neck length. A root portion of the neck portion is disposed between the first and second projections, and defines first and second alcoves between the root portion and the first and second projections, respectively. The dummy mass also includes a distal mass portion defining a distal mass width and a distal mass length. The neck width is less than the mounting plate width, and the neck width is less than the distal mass width.

摘要： A disk drive including a disk having a bottom surface and a base having a first surface lying along a first plane and a second surface lying along a second plane positioned substantially parallel to the first plane. The second surface is spaced apart from the first surface and is beneath at least a portion of the bottom surface of the disk. A damper of the disk drive is located on the second surface adjacent the first surface and is configured to contact a portion of the bottom surface of the disk when the disk is deflected toward the first surface.

摘要： Described herein is a disk drive having a disk receiving surface with an outer diameter. The drive can include a peripheral edge that extends transverse to the disk receiving surface and circumferentially about at least a portion of the outer diameter of the disk receiving surface. The drive can also include a disk limiter that extends between and transverse to the disk receiving surface and the peripheral edge to provide a transition between the disk receiving surface and a surface of the peripheral edge.

摘要： A noise damping system for a disc drive wherein the cover of the disc drive can be made or stamped out of a stainless steel constrained layer of viscoelastic damping material. The material of the cover consists of two layers of stainless steel with a thin layer of damping material sandwiched between. A foam material between the base section of the housing and the printed circuit board located below the housing avoid transmission of vibrations which would in turn generate noise.
