PROBLEM TO BE SOLVED: To prevent dust, which enters from the opening (relief opening) of a tray for inserting a disk, from being deposited on the wiring board of a disk device. SOLUTION: An optical pickup 3 driven to travel in the radius direction of a disk D, which is rotatively driven, facing the recording surface of the disk D, and the wiring board 4 are accommodated in a box-like enclosure body having an opening on its upper surface. The tray 51 provided with the relief opening 55 permitting the optical pickup 3 to travel is arranged in the upper opening of the enclosure body, and a sheet 6, which receives the dust entering from the relief opening 55, is arranged in the inner space of the enclosure body. The sheet 6 is wound on sheet supporting bodies 61 and 61 on the both sides which sandwich the traveling region of the optical pickup 3 so that the fixed position traveling can be made, and is connected to the optical pickup 3 endlessly. The sheet 6 is given a dust-holding property by applying adhesives to the surface of the sheet 6. COPYRIGHT: (C)2005,JPO&NCIPI
