Abstract:
A magnetic head having an active part including an active gap defined by a pair of first and second limbs, the first and second limbs having end faces forming a contact face (11a) for a magnetic tape,the magnetic head also having lateral additional limbs (12) disposed so as to form secondary gaps (13) between the active part and the additional limbs,characterized in that the additional limbs (12) have end faces (12a) arranged as additional contact faces which form a common contact face with the end faces of the first and second limbs for contacting the magnetic tape, the common contact face being formed by portions of a continuously curved surface arranged such that the magnetic tape will contact substantially all of the common contact face, the additional limbs and the active part being a single unit of uniform construction and each of the secondary gaps, whereby the end faces of the additional limbs form a shield for spurious flux, and the contact between the magnetic tape and the end faces of the additional limbs minimizes tape oscillations (13) being wider than the active gap.
