置。[Claims for Utility Model Registration] In an optical information processing device that optically records and reproduces information by irradiating a beam light onto a recording track on an information recording surface of an information recording medium, an objective lens is used to record information on the information recording surface of an information recording medium. an objective lens drive mechanism that drives in a tracking direction perpendicular to the track and a focusing direction perpendicular to the information recording surface; and an optical system that irradiates a beam of light onto the information recording surface through the objective lens and receives reflected light from the information recording surface. a base unit on which the objective lens drive mechanism and the optical system unit are attached, and a first base unit that adjusts the optical axis of the objective lens of the objective lens drive mechanism with respect to the optical axis of the optical system unit.
a unit moving mechanism that supports and moves the base unit in the tracking direction; and a second adjusting mechanism that adjusts the optical axis of the objective lens with respect to the unit moving mechanism. Characteristic optical information processing device.
