ABSTRACT:
A system for recording and/or reproducing signals on a magnetic medium. The system comprises a tape cassette provided with a magnetic tape and an apparatus for cooperation with the tape cassette. The apparatus has a magnetic head comprising at least one magnetoresistive element having an easy axis of magnetization and a defined direction of magnetization extending at least substantially parallel to said axis. The system further comprises a reset cassette which can be loaded into the apparatus and which comprises a housing with a central opening for the passage of the magnetic tape and electronic means, arranged in the housing, for generating a non-alternating magnetic field at the location of the magnetic head when the reset cassette is present in the apparatus, which field has a direction similar to the defined direction of magnetization of the magnetoresistive element.
