ABSTRACT:
A method of reproducing information recorded on an optical recording medium includes the steps of directing a first reading optical beam and a second reading optical beam onto a recording portion on the optical recording medium to obtain a first electric output signal corresponding to the first beam interacting with the optical recording medium and a second electric output signal corresponding to the second beam interacting with the optical recording medium, and performing a non-linear operation and a linear-operation by using these first and second output signals, thereby obtaining an improved reproduced output signal.
