<p>In an optical head device using a float type slide, and an information processing device, influences due to dust is reduced to prevent degradation of recording and reproducing performance. An optical head device has a slider (28) adapted to float up to the surface by an air current accompanying the rotation of a disk-like recording medium, and of the surfaces of the slider, the one which is opposed to the disk-like recording medium is formed with parallel rails (28A, 28B) along the direction of the air current. A rail (29) is formed intermediate between the two rails and beam light focused by an objective lens is allowed to permeate the rail (29) made of transparent material. It is possible to make optical influence hardly producible even if dust particles enter between the slider and the disk-like recording medium.</p> |
