る。2. Description of the Related Art A conventional information processing apparatus incorporating a magnetic recording medium assembly (in which a hard disk or a floppy disk, a magnetic head, a motor serving as a noise source, and the like are built in a metal plate case) is shown in FIG. Since the magnetic recording medium assembly 1 has a mounting structure in which the fixing chassis 3 is directly fixed to the fixing chassis 3 with screws or the like and the fixing chassis 3 is directly fixed to the structure 4 of the information processing apparatus with screws or the like. There has been a problem that vibrations generated by the operation of a drive unit such as a motor built in 1 pass through the fixing chassis 3 and are transmitted to the surrounding structure 4 to generate noise. In order to solve this, as a conventional technique, a magnetic recording medium assembly 1 such as a magnetic disk drive described in Japanese Patent Application Laid-Open No. 4-102286 has been proposed.
A method of lowering the vibration of itself has been considered. However, the noise caused by the magnetic recording medium assembly 1 includes noise generated from the magnetic recording medium assembly 1 itself and noise generated by transmitting vibration of the magnetic recording medium assembly 1 to the surrounding structure 4. To significantly reduce these noises, measures must be taken for both. And,
As for countermeasures, it is necessary to combine vibration isolation and vibration suppression.

音が大きくなってしまう。For example, in the example described in Japanese Patent Application Laid-Open No. 4-102286, the vibration of the magnetic recording medium assembly 1 itself is reduced. However, unless the vibration transmitted to the surroundings is completely cut off, the surrounding structure is not changed. The vibration is transmitted to the body 4. In that case, the radiation area of the noise
Is larger, so it is not possible to expect a large reduction in noise. Further, when the resonance frequency matches the resonance frequency of the structure 4, the noise is further increased.

騒音低減ができていないことである。Problems with the prior art are that both the vibration of the magnetic recording medium assembly 1 itself is reduced and the transmission of vibration from the magnetic recording medium assembly 1 to the surrounding structure 4 is interrupted. Therefore, sufficient noise reduction has not been achieved.

Accordingly, it is an object of the present invention to reduce the noise of the information processing apparatus and to make it possible to use the information processing apparatus comfortably without generating harsh sounds even in a quiet working environment such as a general home.
