A magnetic data transfer head for reading from or writing a substantially rigid magnetic medium comprises a support (15); a pair of pole pieces between which an elongate gap is defined, the pole pieces being mounted to the support; and a contact area (11', 12') including the pole piece faces along which the magnetic medium passes in use. The faces of the pole pieces define the contact area, the length of the gap constituting the largest dimension at the contact area. |
