Abstract
A magnetoresistive head includes a magnetoresistive element sandwiched between a pair of soft magnetic material-made shields to detect signal from a magnetic tape under a magnetoresistance effect, the magnetoresistive element having a magnetic sensor disposed obliquely, at a predetermined azimuth angle, to a direction perpendicular in which the magnetic tape is fed or moved; the magnetoresistive head being installed on a rotating drum to read signal on the magnetic tape by the helical scanning method. A recording/reproducing apparatus includes a rotating drum having installed thereon the magnetoresistive head as reading head and an inductive magnetic head as writing head, to write and/or read signal from the magnetic tape by the helical scanning method.
