<p>A recorder/reproducer comprising a reproducing system for reproducing reproduction data by digitizing a reproduction signal generated from a magnetic tape (140) and extracting a channel clock from the digitized reproduction signal. A crosstalk canceller (130) is provided at the preceding state of a PLL circuit (127) for extracting a channel clock from the reproduction RF data created by digitizing the reproduction signal. The crosstalk canceller (130) comprises a subtracting circuit (131) to which the reproduction RF data is fed and an adaptive filter (132) for generating a psuedo-recording signal crosstalk signal from record data fed from the recording system (110) as a cause signal of the crosstalk signal contained in the reproduction signal and subtraction output data created by the subtracting circuit (131). The psuedo-recording signal crosstalk signal generated by the adaptive filter (132) is fed to the subtracting circuit (131).</p> |
