Systems and manufacturing methods are disclosed herein that can beneficially reduce manufacturing cost while providing size efficient enclosures to house hard drives or other types of storage drives. An enclosure system can be used for separately housing one of two storage devices having different thicknesses. A first portion can be interchangeable with both storage devices. Second and third portions can each have a thickness to size efficiently accommodate the thickness of one storage device. Each of the second and third portions has an engagement surface to engage the first portion forming an enclosure. Either the first portion, or both second and third portions can comprise an opening or a shock mounting element. When the opening or the shock mounting element are on both the second and third portions, the opening or the shock mounting element is collectively identically spaced from the engagement surface on both the second and third portions.

According to one embodiment, a disk device includes a rotatable disk-shaped recording medium, an actuator supporting a head to be movable with respect to the recording medium, and an enclosure includes a base accommodating the recording medium and the actuator, and a cover fixed to the base and includes a peripheral edge portion including a welded portion laser-welded to the base. The welded portion includes weld beads arranged along the entire peripheral edge portion of the cover, and the weld beads include at least two circular weld beads in the peripheral edge portion of the cover.

According to one embodiment, a disk device includes a rotatable disk-shaped recording medium, an actuator supporting a head to be movable with respect to the recording medium, and an enclosure includes a base accommodating the recording medium and the actuator, and a cover fixed to the base and includes a peripheral edge portion including a welded portion laser-welded to the base. The welded portion includes weld beads arranged along the entire peripheral edge portion of the cover, and the weld beads include at least two circular weld beads in the peripheral edge portion of the cover.

Various embodiments for audibly mapping computing components in a computer storage system, by a processor device, are provided. In one embodiment, a method comprises creating a detectible audible pattern using an actuator arm and head assembly of a hard disk drive operating in the computer storage system for physically mapping the hard disk drive to a logical location within the computer storage system.

A disk device according to one embodiment includes a base, a first cover, a second cover, and a damper. The base includes a bottom surface, a side wall protruding in a first direction from the bottom surface, and a support surface located at an end of the side wall in the first direction. The first cover is attached to the base to close the inner space. The second cover is joined to the base while being supported by the support surface, to cover the first cover. The damper includes a constrained layer in-between the first cover and the second cover and a viscoelastic material between the first cover and the constrained layer. The constrained layer includes a smaller-thickness part extending along the support surface and a larger-thickness part connected to the smaller-thickness part.

Certain exemplary aspects of the present disclosure are directed towards an apparatus in which a base deck and a forged base deck cover are coupled to one another, via a weld joint, to provide a hermetically sealed cavity within. The base deck includes an outer region, and the base deck cover includes a lip that interfaces with the outer region of the base deck to provide the weld joint. Similarly, the base deck is formed by an outer region of a base deck bottom portion interfacing with a lip of the shroud to form, via welding, the base deck.

A disk device according to one embodiment includes a base, a first cover, a second cover, and a damper. The base includes a bottom surface, a side wall protruding in a first direction from the bottom surface, and a support surface located at an end of the side wall in the first direction. The first cover is attached to the base to close the inner space. The second cover is joined to the base while being supported by the support surface, to cover the first cover. The damper includes a constrained layer in-between the first cover and the second cover and a viscoelastic material between the first cover and the constrained layer. The constrained layer includes a smaller-thickness part extending along the support surface and a larger-thickness part connected to the smaller-thickness part.

A base plate is a portion of a housing of a disk driving device having a disk rotating with a rotation axis as a center, and is a cast product. The base plate has a bottom plate part and a peripheral wall part. The bottom plate part has a rectangular shape when viewed in an axial direction. The peripheral wall part extends from an outer peripheral edge of the bottom plate part toward a side of the axial direction to surround the periphery of the bottom plate part. A metal member embedded in the peripheral wall part is provided.
