ABSTRACT:
A disc drive apparatus has a base, a disc, and a carriage. The base has a first vibration mode and a second vibration mode as reference vibration modes with respect to frequency response characteristics observed when the disc drive apparatus is shaken. The second vibration mode has a low-frequency second vibration mode (Base 2nd-1), in which a waveform peak is created on the low-frequency side, and a high-frequency second vibration mode (Base 2nd-2), in which a waveform peak is created on the high-frequency side. The two second vibration modes (Base 2nd-1 and Base 2nd-2) have a relationship such that the phase of a pivot position is inverted between them. A frequency of a first bending mode of an arm of the carriage is set in a frequency domain in a trough between the two second vibration modes.
