Abstract

PURPOSE: To prevent dust from sticking to an aperture lens that moves in a disk center direction, by covering the aperture lens with a deck surface at a position other than a reproduction position.
CONSTITUTION: Aperture lens 12 of optical system 18 that provides optical recording and reproduction by moving from the outer circumference of disk 3 in the center direction through transportation screw 22, etc., is covered with deck 5 at position 12' other than a reproduction position. Therefore, even when cover 2 is left open by mistake, dust, etc., is prevented from sticking to lens 12, so that the recording and reproducing performance will never deteriorate.
