PURPOSE: An optical detector unit and an optical pickup and optical information storage medium system including thereof are provided to reduce a width to a height direction of an optical pickup by improving an arrangement of a land which is an input-output terminal of an optical detector integrated circuit (IC), and by improving a contact point and a wiring of the a printed circuit board (PCB) since corresponding to the improved arrangement of the land. CONSTITUTION: A main light receiving unit and a sub light receiving unit of an optical detector integrated circuit (IC) (60) comprise a respective light receiving unit and lands (69). A printed circuit board (PCB) is combined with the optical detector IC in order to contact with multiple lands. The multiple lands are arranged in order to comprise two strings to a height direction of an optical pickup. A part wiring of a wiring formed on the PCB' is extended to a lateral direction crossed in a height direction of the optical pickup.
