ヘツド。[Claims for Utility Model Registration] (1) A laser output section that is disposed in a fixed position and outputs a laser beam in a straight line direction, supported movably in the straight line direction by a guide member, and The base of an optical pickup device includes an irradiation unit that focuses and irradiates the laser beam onto an optical recording medium arranged parallel to the optical recording medium, and a light receiver that receives the reflected light reflected by the optical recording medium. The reflected light corresponding to information recorded on the optical recording medium is transmitted to the optical recording medium while changing the irradiation area of the optical recording medium with the laser beam by moving the irradiation unit in the linear direction. 1. An optical pick-up head for detecting light with a light receiver, characterized in that the laser output section is fixed to the guide member. (2) The irradiation unit includes a focusing servo mechanism that focuses the laser beam on the optical recording medium, and a tracking servo mechanism that adjusts the irradiation area of the laser beam to match the track of the optical recording medium. 2. The optical pickup head according to claim 1, wherein the focusing servo mechanism and the tracking servo mechanism are controlled based on reflected light received by the light receiver.
