ABSTRACT:
A crosstalk detecting apparatus for detecting crosstalk which may occur upon reading an FM-modulated signal recorded on a recording medium, wherein the crosstalk detecting apparatus outputs a crosstalk amount from an adjacent track based on a signal read by a pickup. On a medium with which this crosstalk detecting apparatus can detect crosstalk, an image signal and an identification signal are FM-modulated and recorded on each of three tracks adjacent to one another, and the FM-modulated identification signal is recorded on each of the three tracks such that initial phases of the FM-modulated identification signals are all made equal. Also, the crosstalk detecting apparatus includes a timing pulse generator for generating a pulse at a predetermined time within the identification signal period; a phase detecting circuit for detecting a phase difference for the case where no crosstalk appears in a signal read from a central track; and a sampling circuit for sampling the output from the phase detecting circuit with a timing pulse generated by the timing pulse generator.
