Abstract
An information reproducing apparatus for simultaneously reproducing information recorded on a recording medium such as a magneto-optical disk through a plurality of information channels by using a multibeam spot of a laser beam includes a circuit for generating a reproduction signal on the basis of a signal detected from one of the information channels and a signal detected from another information channel. The generating circuit includes a light source, a photodetective sensor, a waveform equalizing circuit, and a binarizing circuit provided in correspondence to each information channel and a data separator for generating reproduction data on the basis of an output of each binarizing circuit and a clock signal.
