Abstract
An optical disk device is adapted so that an air-cooling fan for cooling is attached to the back side of the optical disk device body unit. Further, in this optical disk device, a control board is disposed or arranged at the back side of the air-cooling fan so that it is integral with the optical disk device body unit to thereby cool heat produced in the optical disk device by blast of the cooling fan to allow the ambient temperature to fall within a specification limit, thus to facilitate the optical disk device to be included in a computer, etc.
