ABSTRACT:
The invention relates to a magnetic recording/reproducing device in which a reproduce head is positioned where the crosstalk between adjacent tracks in a magnetic disk is minimized to maintain an adequate transfer rate in a system involving great crosstalk. The removal of crosstalk ensures the reproduction of the recorded data and thus increases the reliability of the magnetic recording/reproducing device. The magnetic recording/reproducing device according to this invention includes a magnetic disk on which a plurality of tracks are concentrically formed, and data are recorded at different frequencies on adjacent tracks.
