Patent ID: 7684183

Claim:
A supporting structure of a hard disk drive unit (HDD unit) in an information processor, the information processor comprising: the HDD unit; a box having a spacer for storing the HDD unit; and an impact buffer, wherein the impact buffer comprises two or more spaced apart impact buffering members with different hardness, the impact buffering members include at least a first impact buffering member and a second impact buffering member with a hardness lower than that of the first impact buffering member, the first impact buffering member and the second impact buffering member are disposed on at least one surface of a side surface part of the HDD unit, the side surface part being orthogonal to a magnetic disk surface of the HDD unit, and when the impact buffer is compressed and deformed by an impact applied to the HDD unit, the impact buffer which is spaced apart supports and expands/contracts so that the HDD unit rotates in a head unloading direction of a head arm of the HDD unit, and the first impact buffering member and the second impact buffering member buffer the impact applied to the HDD unit.
