ABSTRACT:
An optical disc apparatus according to the present invention includes a disc rotation mechanism2for allowing an optical disc1having an information recording face to be placed thereon and rotating the optical disc1; an optical pickup3including an engaging section and irradiating the information recording face with a light beam to perform at least one of information recording and information reproduction; a base main body13for rotatably supporting the optical pickup and having the disc rotation mechanism; a driving source5, supported by the base main body, for generating a force for rotating the optical pickup; and a driving force transmission mechanism610supported by the base main body, including a worm, and engaged with the engaging section to transmit a driving force of the driving source to the optical pickup, thereby rotating the optical pickup. A distance between the engaging section and a rotating axis of the optical pickup is longer than a distance between the center of gravity of the optical pickup and the rotating axis of the optical pickup.
