ABSTRACT:
An optical pick-up driving device includes: a base; a rotary arm installed with respect to the base and operative to rotate around a first guide pin; a rotation driving mechanism, arranged along the rotary arm and said base, for rotating the rotary arm; an optical pick-up assembly coupled with the rotary arm and operative to rotate around a second guide pin; and an interlocking mechanism for rotating the optical pick-up assembly and which is interlocked with the rotation of the rotary arm. Another optical pick-up driving device includes: a base; an optical pick-up rotatably supported by the base; a rotation driving unit for rotating the optical pick-up; and a moving unit for guiding the movement of the optical pick-up. The moving unit includes: a first guide pin installed at one portion of the base being spaced by a predetermined distance, from the optical pick-up; a second guide pin installed on the base to be nearer to the optical pick-up than the first guide pin; a first arm where a guide slot slidably coupled with the first guide pin is formed at one end thereof and the optical pick-up is installed at the other end thereof; a second arm of which one end is rotatably coupled with the second guide pin; and a unit for coupling the first and second arms so that they rotate interlockingly. Therefore, an accurate tracking control is possible.
