Abstract
An optical disk apparatus includes an optical disk drive including an optical disk and an optical head, a power source for supplying electric power to the optical disk drive an apparatus casing for enclosing at least the optical disk drive and the power source, and a first air feed member having a first air passage. The first air feed member includes a first air inlet for introducing cooling air into the apparatus casing from outside of the apparatus casing so as to cool the optical disk drive, and an air filter disposed upstream of the optical disk drive in the first air passage such that the cooling air flows into the optical disk drive through the air filter. A second air feed member has a second air passage and included a second air inlet for introducing cooling air into the apparatus casing from outside of the apparatus casing so as to cool at least the power source. A partition member is provided for separating the first and second air passages from each other. The flow rate of the cooling air in the first air passage is set to such a value as to maintain the optical disk drive at a predetermined temperature or less such that the optical disk drive is not polluted with airborne dust.
