Patent ID: 7463559

Claim:
An optical disk apparatus comprising: an optical pickup that has a first laser emission device emitting laser light for recording or playing back signals on or from a first disk medium and a second laser emission device emitting laser light for recording or playing back signals on or from a second disk medium different in a signal format from the first disk medium; a lead-out board on which a first lead-out conductor connected to one electrode of the first laser emission device and led out, a second lead-out conductor connected to one electrode, which is of the same polarity as the one electrode of the first laser emission device, of the second laser emission device and led out, and a third lead-out conductor connected to both the other electrodes of the first and second laser emission devices and led out are arranged respective predetermined spaces apart, and which is to be electrically connected to a circuit board having circuits for driving an optical disk apparatus mounted thereon; first connection areas to short-circuit by solder at a portion of opposing parts of any two adjacent lead-out conductors of the first, second, and third lead-out conductors partially in the width direction crossing the longitudinal direction and to open the short circuit; and second connection areas to short-circuit by solder at a portion of opposing parts of the other pair of two adjacent lead-out conductors of the first, second, and third lead-out conductors partially in the width direction crossing the longitudinal direction and to open the short circuit, wherein the first connection areas and the second connection areas are arranged in a staggered pattern in the longitudinal direction of the lead-out conductors.
