Claims

[Claims for Utility Model Registration] An optical system that focuses a light beam from a light source onto an information track on the surface of an information recording medium and detects reflected light from this track;
A lens barrel for holding the optical system, a support guide means for making the lens barrel freely movable in a focus control direction and a predetermined direction perpendicular thereto, and a driving means for driving the lens barrel. In an optical recording/reproducing device, 1. a rotation axis for rotating the lens barrel in a tracking control direction substantially perpendicular to the optical axis of the optical system and a time axis control direction substantially perpendicular to the tracking control direction; A sliding groove for sliding in the optical axis direction is struck on either the side surface of the lens barrel or a stationary member of the optical recording/reproducing device extending in the optical axis direction to support the lens barrel. An optical recording/reproducing device comprising a guide means.
