Abstract:
A recording/reproducing apparatus for a disc, comprising:a disc tray mounted for movement between a position protruded from a casing via an aperture formed therein and a position housed within said casing, said disc tray having a recess in which to set the disc;a movement mechanism for moving said disc tray between the protruded position and the housed position, said movement mechanism including a lift mechanism for lifting or lowering the disc tray in a direction normal to the direction of movement between the protruded position and the housed position when said disc tray reaches the housed position, said lift mechanism including a control gear arranged in said casing, a planar surface of said control gear oriented in a perpendicular direction to a planar surface of said disc tray recess and the edge surface of the control gear, and said control gear having a cam groove, wherein the disc tray reaching said housed position is lifted or lowered along said cam groove;an optical pickup for illuminating a light beam on said disc transported by said disc tray; an adjustment mechanism for adjusting a tilt relative to the disc of the optical axis of the light beam radiated by said optical pickup to said disc, said adjustment mechanism being driven by said control gear; anda detection unit for detecting the tilt relative to the disc of the optical axis of the light beam radiated by said optical pickup to said disc, said control gear being driven based on a detection output from said detection unit;wherein said adjustment mechanism includes a guide mechanism for guiding the optical pickup at least in a radial direction of the disc, said control gear having a further cam groove for adjusting the tilt relative to the disc of the optical axis of the light beam radiated by said optical pickup to said disc. said guide mechanism engaging with said further cam groove for adjusting the tilt relative to the disc of the optical axis of the light beam radiated to said disc.
