description The magnetic recording device with rotating head according to the invention comprises a magnetic recording medium, a cylindrical and rotating head, a fixed magnetic excitation circuit; the head comprising, on its surface, two movable pole pieces separated by a gap and each magnetically linked to an initial and a second magnetic circuit in the shape of a portion of a ring and providing a rotating joint to the passage of the magnetic flux, with the fixed, magnetic excitation circuit possessing an excitation coil that induces an magnetic field in a magnetic circuit having two fixed pole pieces, each magnetically coupled by a gap to one of the said rings. Application: Video tape recorders in particular.
