A REPRODUCING APPARATUS HAVING AN ARITHMETRIC CIRCUIT TO LINEARLY COMBINE AN INVERSE MATRIX OF CROSSTALK RATIOS RELATIVE TO THE ADJACENT TRACKS AND SIGNALS READ FROM THE ADJACENT AND TRACED TRACKS

A recorded-information reading apparatus includes a pickup device for reading recorded signals from a recording medium. The read signals are supplied to a signal processing device for the purpose of signal processing. The signal processing device includes a memory device for storing the read signals for respective signal tracks on the recording medium. The stored data are supplied to an arithmetic device for the purpose of arithmetic processing. The arithmetic device uses the stored data to perform arithmetic operations for cancelling crosstalk components which come from the adjacent tracks to the signal read from a track which is being traced and then for estimating a true signal recorded on the track which is being traced. In this manner, the recorded-information reading apparatus eliminates the crosstalk components by processing the signals recorded on the recording medium without the need to use any special detecting mechanism.
