Abstract
The hard disk drive device includes a casing, a hard disk drive unit, and cushioning members interposed between the hard disk drive unit and the inside wall of the casing and adapted to receive stress and absorb impact stress through strain. The cushioning members include a first layer situated towards the inside wall of the hard disk drive unit, a second layer situated towards the hard disk drive unit, and a third layer situated between the first layer and the second layer. The individual materials of the cushioning members are established such that the third layer has lower hardness than the first layer and the second layer, based on JIS K6253 standard.
Claims3
A storage device comprising a casing that defines a housing chamber;
- a disk drive unit housed within the housing chamber;
- and a cushioning member interposed between the disk drive unit and an inside wall of the casing and adapted to receive stress and absorb impact stress through strain;
- wherein the cushioning member includes a first layer situated towards the inside wall of the casing, a second layer situated towards the disk drive unit, and a third layer situated between the first layer and the second layer;
- and
- materials of the cushioning member are established such that the third layer has lower hardness than the first layer and the second layer, wherein T1:T2=1:1-3, and T1:T3=1:1-5, where T1, T2, and T3 designate thickness of the first layer, the second layer, and the third layer respectively.
