Optical pickup projecting two laser beams from apparently approximated light-emitting points

An integrated type optical pickup module comprising:

• a first semiconductor laser and a second semiconductor laser;
• and
• an optical element interposed between said first and second semiconductor lasers, said optical element having a first reflecting surface and a second reflecting surface perpendicular to said first reflecting surface, said first reflecting surface reflecting a laser beam projected from said first semiconductor laser, said second reflecting surface reflecting a laser beam projected from said second semiconductor laser,
• wherein a heterojunction surface of said first semiconductor laser is substantially perpendicular to said first reflecting surface, and a heterojunction surface of said second semiconductor laser is substantially perpendicular to said second reflecting surface.

An optical pickup comprising:

• a laser beam source;
• and
• an optical system which guides a laser beam projected from said laser beam source toward an optical recording medium and receives the laser beam reflected by the optical recording medium so as to guides the reflected laser beam to light-receiving elements,
• wherein said laser beam source includes an integrated type optical pickup module comprising:
• a first semiconductor laser and a second semiconductor laser;
• an optical element interposed between said first and second semiconductor lasers, said optical element having a first reflecting surface and a second reflecting surface perpendicular to said first reflecting surface, said first reflecting surface reflecting a laser beam projected from said first semiconductor laser, said second reflecting surface reflecting a laser beam projected from said second semiconductor laser, said optical element further having a mounting surface perpendicular to both said first and second reflecting surfaces;
• and
• a submount having a top surface on which said first and second semiconductor lasers are mounted,
• wherein said optical element is mounted to said submount via said mounting surface of said optical element.
