Magnetic disk device

Abstract

Abstract PURPOSE:To reduce the transmissibility of vibration and to suppress the maximum value of displacement due to shock to an allowable limit or less by inserting a two-layer structure body consisting of an elastic member having a high spring constant and a high attenuation factor and an elastic material having a low spring constant and a high attenuation factor between a disk enclosure and a base. CONSTITUTION:Each two-layer structure body 10 is constituted by laminating the 1st and 2nd members 11, 12 and respective bodies 10 are distributed and inserted between the external bottom face of the disk enclosure 1 and the fitting face of the base 2. In the 1st member 11, the maximum displacement against shock is suppressed to an allowable limit or less by its high attenuation factor and the transmissivility of high frequency vibration can be reduced by its high spring constant. In the 2nd member 12, the transmissibility of especially low and medium frequency vibration is reduced by its low spring constant and high attenuation factor. Thereby, the transmissibility of low, medium and high frequency vibration can be reduced as a whole and the maximum displacement due to shock can be suppressed to the allowable limit or less.
