A read/write head for use in a magnetic storage device in a digital data processing system for writing data in the form of magnetic flux onto, and reading data from a spinning magnetic disk. The head has two magnetic pole pieces (11, 12) each with a yoke region (13) which tapers to a pole tip (14) and an energizable coil (16) situated between the pole pieces in the yoke region for generating magnetic flux. One of the pole pieces has a slot (17) in the yoke region, and a strip (20) of magneto-resistive material is situated adjacent the slot. The magneto-resistive strip is adapted to be connected to sensing equipment which measures variations in the resistance of the magneto-resistive strip in response to the variations in the magnetic flux recorded on the media. Several slots may be formed in the pole pieces, and an elongated magneto-resistive strip (42) may be situated adjacent the slots. |
