ABSTRACT:
A recording-medium reproducing apparatus in which different types of recording mediums can be reproduced by the single reproducing apparatus. The apparatus selectively reproduces information from a first recording medium by applying light to an information recording layer through a transparent substrate having a first thickness, and reproduces information from a second recording medium by applying light to an information recording layer through a transparent substrate having a second thickness. The apparatus has a light-generating device for generating light to be applied to the information recording layer of the recording medium. A light-applying device converges the light generated by the light-generating device and applies it to the information recording layer of the recording medium. A light-receiving device, which is divided into a central portion and a peripheral portion, separately receives the light reflected by the recording medium.
