る光学式情報記録再生装置。 In an optical information recording/reproducing device that reads information on the recording surface of a recording medium or records desired information on the recording surface of a recording medium, an objective lens is used to focus light from a light source onto the recording surface as a light spot. A two-axis actuator that moves in a direction perpendicular to the axial direction and the optical axis by sliding in the axial direction and pseudo-movement by rotating around the guide shaft using one guide shaft, and at least the part that fits with the guide shaft. 1. An optical information recording/reproducing device characterized in that it is made of plastic.
