IPC: G11B7/131
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To read data of a DVD and a CD whose substrates are different from each other in thickness, with one optical pickup device. SOLUTION: The CD 10 or the DVD is irradiated with laser beams via a beam splitter 42 and an objective lens 43 by a laser diode 41. Then, the laser beams reflected on the CD 10 or the DVD is incident on a photodiode 61 via the objective lens 43 and the beam splitter 42.
