摘要： An optical disc drive apparatus includes a reference base. A turntable provided on the reference base operates for receiving an optical disc thereon. An optical pickup head supported by a guide shaft is movable along the guide shaft in a radial direction of the optical disc on the turntable. A movable base supports the guide shaft, and is movably connected to the reference base. The movable base is inclined relative to the reference base at an adjustable inclination angle. A mechanism operates for moving the movable base relative to the reference base and adjusting the inclination angle to correct a tilt of an optical axis of the optical pickup head with respect to an information recording surface of the optical disc on the turntable. A plurality of guide members fixed to the reference base have respective guide surfaces. Guide rollers connected to the guide shaft are in contact with the guide surfaces of the guide members respectively.
