Abstract
Embodiments of the invention provide a disk drive device excellent in reliability that can reduce influence of a temperature change in an environment of use. In one embodiment, a disk drive device includes a disk drive mechanism that records information in a disk or reproduces information stored in the disk and a housing in which the disk drive mechanism is housed. The disk drive device further includes a humidity control element that controls humidity in the inside of the housing, a temperature sensor that detects ambient temperature of the disk drive device or temperature of a portion where temperature changes substantially in the same manner as the ambient temperature, and a control circuit that controls the temperature control element on the basis of a rapid change in temperature detected by the temperature sensor.
