<p><P>PROBLEM TO BE SOLVED: To enhance the cooling performance of an apparatus in a device without positively introducing outside air into the device. <P>SOLUTION: This disk device relating to this embodiment uses differential pressure between pressure at an inner side in a radial direction of an optical disk 14 and pressure at an outer side in the radial direction generated by the rotations of the optical disk 14 to circulate air inside the disk drive. The differential pressure generated by the rotations of the optical disk 14 guides warmed up air below a disk tray 3 into between the disk drive and a casing 2 through an air inlet path 30. The air is cooled by air outside the casing and subsequently, is sucked into the inner side in the radial direction of the optical disk 14 through an air deriving part 35. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
