Apparatus for reproducing information by delaying and attenuating a reproducing signal |
摘要 |
An apparatus for reproducing information is adapted to irradiate a laser beam onto a recording surface of an information recording optical disk on which record information are written to transform a reflected laser beam from the recording surface to an electric signal by using a photoelectric transducer, thus to reproduce record information on the basis of this electric signal. The apparatus has a signal delayer for delaying an electric signal by a predetermined time, a signal attenuator for attenuating the delayed signal, and a signal subtracter for subtracting the delayed signal from the electric signal to output a subtraction signal.
