PROBLEM TO BE SOLVED: To well maintain the following-up movement of a laser beam to the information recording row in an optical recording medium, in an optical system integrated type optical pickup. SOLUTION: Optical devices such as an objective lens 101, semiconductor laser 102, mirror 104, and light receiving element 103 are mounted on a movable housing 105 which is held on a fixing member 106 through plural wires 109 arranged parallelly to each other. As a result, the movable housing 105 is made displaceable in the tracking direction (X direction) and the focusing direction (Y direction) relative to the fixing member 106. The plural wires 109 are, in a mutually insulated state, combined to the movable housing 105 and the fixing member 106, and are used as a power feeding line or a signal line to the semiconductor laser 102 or the light receiving element 103 inside the movable housing 105. |
