The information storage device includes a device housing with a generally rectangular bay to accommodate a disk drive. The generally rectangular bay includes a base portion and a plurality of side portions. The information storage device further includes a damping insert sheet disposed between the disk drive and the base portion. The damping insert sheet has a plurality of elastomeric cushions, for example with a cushion thickness in the range 0.5 mm to 10 mm, and a spanning sheet, for example having a sheet thickness in the range 0.02 mm to 0.35 mm. Each of the plurality of elastomeric cushions is attached to the spanning sheet. Each of the plurality of elastomeric cushions contacts and is compressed between the generally rectangular bay and the disk drive. ## Claims ### Claim 1 An information storage device comprising: a disk drive; a device housing that includes a generally rectangular bay to accommodate the disk drive, the generally rectangular bay including a base portion and a plurality of side portions; and a damping insert sheet disposed between the disk drive and the base portion, the damping insert sheet comprising a plurality of elastomeric cushions; and a spanning sheet, each of the plurality of elastomeric cushions being attached to the spanning sheet and being thicker than the spanning sheet; wherein each of the plurality of elastomeric cushions contacts and is compressed between the generally rectangular bay and the disk drive. ### Claim 2 (depends on 1) The information storage device of claim 1 wherein the disk drive has a head-disk assembly and a printed circuit board assembly (PCBA) attached to the head-disk assembly, the head-disk assembly including a disk drive cover that does not face the disk drive PCBA, and wherein the dampening insert sheet is disposed between the disk drive PCBA and the base portion, with at least one of the plurality of elastomeric cushions contacting the disk drive PCBA. ### Claim 3 (depends on 2) The information storage device of claim 2 further comprising a bay cover that encloses the disk drive within the generally rectangular bay, the disk drive cover being adjacent and facing the bay cover. ### Claim 4 (depends on 1) The information storage device of claim 1 wherein the disk drive has a head-disk assembly and a printed circuit board assembly (PCBA) attached to the head-disk assembly, the head-disk assembly including a disk drive cover that does not face the disk drive PCBA, and wherein the dampening insert sheet is disposed between the disk drive cover and the base portion, with at least one of the plurality of elastomeric cushions contacting the disk drive cover. ### Claim 5 (depends on 4) The information storage device of claim 4 further comprising a bay cover that encloses the disk drive within the generally rectangular bay, the disk drive PCBA being adjacent and facing the bay cover. ### Claim 6 (depends on 1) The information storage device of claim 1 wherein the disk drive defines a plurality of external disk drive corners and the plurality of elastomeric cushions contacts and is compressed between the generally rectangular bay and the disk drive adjacent a respective one of the external disk drive corners. ### Claim 7 (depends on 1) The information storage device of claim 1 wherein the plurality of side portions meet to define a plurality of internal bay corners adjacent the base portion, and each of the plurality of elastomeric cushions contacts and is compressed between the generally rectangular bay and the disk drive adjacent a respective one of the plurality of internal bay corners. ### Claim 8 (depends on 1) The information storage device of claim 1 wherein the spanning sheet comprises a polymer material that is doped with an electrically dissipative dopant. ### Claim 9 (depends on 1) The information storage device of claim 1 wherein the spanning sheet comprises a polymer material that is coated with an electrically dissipative coating. ### Claim 10 (depends on 1) The information storage device of claim 1 wherein the plurality of elastomeric cushions comprises a polyurethane foam doped with an electrically dissipative dopant. ### Claim 11 (depends on 1) The information storage device of claim 1 wherein the plurality of elastomeric cushions comprises a viscoelastic material coated with an electrically dissipative coating. ### Claim 12 (depends on 1) The information storage device of claim 1 wherein the elastomeric cushions have a cushion thickness in the range 0.5 mm to 10 mm, and the spanning sheet has a sheet thickness in the range 0.02 mm to 0.35 mm. ### Claim 13 A method to manufacture an information storage device, the method comprising: providing a device housing that includes a generally rectangular bay, the generally rectangular bay including a base portion and a plurality of side portions; inserting a damping insert sheet into the generally rectangular bay, the damping insert sheet comprising a plurality of elastomeric cushions and a spanning sheet, each of the plurality of elastomeric cushions being attached to the spanning sheet and being thicker than the spanning sheet; and placing a disk drive into the generally rectangular bay, with the damping insert sheet disposed between the disk drive and the base portion, with each of the plurality of elastomeric cushions contacting and being compressed between the generally rectangular bay and the disk drive. ### Claim 14 (depends on 13) The method of claim 13 wherein the disk drive has a head-disk assembly and a printed circuit board assembly (PCBA) attached to the head-disk assembly, the disk drive PCBA including an electrical connector, and wherein placing the disk drive into the generally rectangular bay includes attaching the electrical connector to a mating electrical connector of the information storage device. ### Claim 15 (depends on 14) The method of claim 14 wherein the head-disk assembly includes a disk drive cover that does not face the disk drive PCBA, and placing the disk drive into the generally rectangular bay results in the dampening insert sheet being disposed between the disk drive cover and the base portion with at least one of the plurality of elastomeric cushions contacting the disk drive cover. ### Claim 16 (depends on 15) The method of claim 15 further comprising enclosing the disk drive within the generally rectangular bay by attachment of a bay cover to the information storage device, with the disk drive PCBA adjacent and facing the bay cover. ### Claim 17 (depends on 13) The method of claim 13 further comprising enclosing the disk drive within the generally rectangular bay by attachment of a bay cover to the information storage device. ### Claim 18 (depends on 13) The method of claim 13 wherein the plurality of side portions meet to define a plurality of internal bay corners adjacent the base portion, and placing the disk drive into the generally rectangular bay includes compressing the plurality of elastomeric cushions between the generally rectangular bay and the disk drive adjacent a respective one of the internal bay corners. ### Claim 19 (depends on 13) The method of claim 13 wherein the spanning sheet comprises an electrically dissipative polymer material. ### Claim 20 (depends on 13) The method of claim 13 wherein the plurality of elastomeric cushions comprises an electrically dissipative viscoelastic material.
