摘要： A pre-pit detector comprises an optical detector which receives a reflected beam of an optical beam irradiated to the write surface by first and second light reception surfaces, which are split light reception surfaces, to output first and second optical detection signals corresponding to reception light intensities of the respective first and second light reception surfaces and receives the reflected beam from a pre-pit track pairing up with an information write track to which the optical beam is irradiated, on the first light reception surface. The first optical detection signal is given with an amplification result by a greater gain than the second optical detection signal to supply the first and second optical detection signals to a subtractor which computes the difference between the first and second optical detection signals. The output signal of the subtractor is digitized to generate a pre-pit detection signal.
