Abstract: PROBLEM TO BE SOLVED: To provide a disk device capable of improving shock characteristics.
SOLUTION: This disk device is provided with a base, a disk rotated by a spindle motor, and a carriage having an arm rotated around a pivot shaft. The base has primary and secondary vibration modes as reference vibration modes regarding frequency response characteristics when the disk device is vibrated. The secondary vibration mode has a low frequency side secondary vibration mode (Base 2nd-1) where a peak is generated in a waveform on a low frequency side and a high frequency side secondary vibration mode (Base 2nd-2) where a peak is generated in a waveform on a high frequency side. The two secondary vibration modes (Base 2nd-1) (Base 2nd-2) have a relation between each other that the phase of a pivot position is reversed between the two secondary vibration modes. The frequency of the primary bending mode of the arm is set in the frequency band of a trough formed between the two secondary vibration modes.
