Patent ID: 7768895

Claim:
An optical pickup device, comprising: a first light source that radiates first laser light; a second light source that radiates second laser light of which the wavelength is smaller than the first laser light; a first condensing member that condenses the first laser light onto a recording medium for the first laser light; a second condensing member that condenses the second laser light onto a recording medium for the second laser light; a first optical member that reflects the first laser light radiated from the first light source onto the first condensing member and transmits the second laser light radiated from the second light source; a second optical member that reflects some of the second laser light radiated from the second light source, after being transmitted through the first optical member, onto the second condensing member and transmits the rest of the radiated second laser light; and a light receiving sensor that receives the rest of the second laser light transmitted through the first optical member and the second optical member so as to detect an amount of second laser light, wherein the first condensing member, the second condensing member and the light receiving sensor are disposed substantially linearly relative to each other.
