<P>PROBLEM TO BE SOLVED: To provide a printed circuit board that prevents dielectric breakdown of a laser diode assembled in an optical pickup device performing reading operation of a signal recorded in a signal recording layer provided in an optical disk. <P>SOLUTION: An anode pattern 7 connected to an anode of the laser diode and a cathode pattern 8 connected to a cathode of the laser diode are disposed in proximity to each other on the printed circuit board 6, a magnetic material 9 which is attracted by a magnet 11 provided on a short-circuiting component 10 is provided between the anode pattern 7 and the cathode pattern 8, and the anode pattern 7 and the cathode pattern 8 are made to be short-circuited by the short-circuiting member 10 when attracting the magnet 11 provided on the short-circuiting component 10 is attracted by the magnetic material 9. <P>COPYRIGHT: (C)2011,JPO&INPIT |
