Estimating the term…
A magnetic signal reproducing apparatus which can lessen fluctuation of reproduced outputs in reproducing magnetic signals recorded in a magnetic tape by a magneto-resistance effect type magnetic head even if a magnetic tape sliding face of the magneto-resistance effect type magnetic head is abraded. A current value of a sense current when a voltage fluctuation level of the sense current caused when a magnetic field in the normal direction is applied to a magneto-resistance effect element of the magneto-resistance effect type magnetic head is equal with a voltage fluctuation level of the sense current caused when a magnetic field in the opposite direction is applied thereto is set to a predetermined value I0. Then, the current value of the sense current supplied to the magneto-resistance effect element of the magneto-resistance effect type magnetic head is set to be greater than I0 in reproducing the magnetic signals recorded in the magnetic tape.
A magnetic signal reproducing apparatus, comprising:
A magnetic signal reproducing method for reproducing magnetic signals recorded in a magnetic tape by a magneto-resistive effect type magnetic head that is subject to abrasive wear from an initial state that reproduces the magnetic signals, the method comprising the steps of:
