An optical disk recording and/or reproducing apparatus, records and/or reproduces information on an information record surface of an optical disk loaded thereto. The optical pickup apparatus for the optical disk recording and/or reproducing apparatus is provided with: a base having a pair of plate portions opposed to each other; two types of optical pickups; first and second guiding rails arranged substantially parallel to each other and disposed on the plate portions of the base respectively, for respectively guiding the optical pickups along the information record surface of the loaded optical disk in a radial direction of the loaded optical disk; first and second retracting rails respectively connected to the first and second guiding rails, for retracting thereonto the optical pickups from the first and second guiding rails through linkages with the first and second guiding rails respectively; a rotator frame for holding the first and second retracting rails; a swinger frame, for holding the rotator frame through a first spindle parallel to the first and second retracting rails, held by the base through a second spindle parallel to the first spindle; a swinging mechanism for swinging the swinger frame around the second spindle; and a rotating mechanism for rotating the rotator frame and for swapping the first and second retracting rails to each other after the swinging mechanism swings the swinger frame toward one direction.
