Abstract
A magnetic signal reproducing method and apparatus of the helical scan system employing an MR head. The apparatus includes a substantially cylindrically-shaped rotary drum, an inductive magnetic head loaded on the rotary drum, a magneto-resistive effect magnetic head having an amount of protrusion from the rotary drum smaller than that of the inductive magnetic head, a tape sort detection unit, and a tape tension control unit. If information signals are reproduced by the inductive magnetic head, the tape tension of the magnetic tape is decreased by the tape tension control unit and, if information signals are reproduced by the magneto-resistive effect magnetic head, the tape tension of the magnetic tape is increased by the tape tension control unit.
