Abstract
A magnetic recording/reproducing apparatus of the helical scan system employing a MR head as a reproducing magnetic head. The magnetic recording/reproducing apparatus includes a MR head 6 and a rotary drum carrying the MR head 6. In reproducing signals from the magnetic tape 7 in accordance with the helical scan system, a magnetic tape 7, having a large number of projections 7c on the tape surface and containing an electrically conductive material in its magnetic layer, is used as a recording medium.
