ABSTRACT:
When a type of an optical disc is discriminated by disc type discriminating processing, search operation by a CD light beam is carried out in CD discriminating processing, and a distance from a position xf where a large signal change of a first time is detected as a fake phenomenon to a position xs where the large signal change of a second time corresponding to a recording layer is detected as a moving distance d3. Based on the moving distance d3, whether the optical disc is a CD medium is determined. In this manner, whether the optical disc is the CD medium or not can be determined correctly with high precision.
