情報記録再生装置。 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. The means for moving in the axial direction and the direction perpendicular to the optical axis is achieved by condensed movement by sliding in the axial direction and rotating around the guide axis using a guide pipe fixed to the objective lens holder and one guide shaft. 1. An optical information recording and reproducing device that is a biaxial actuator, characterized in that the shaft diameter of the guide shaft that fits near both ends of the guide pipe is larger than that near the center of the guide shaft.
