Abstract
Improved recording head structures having lower recording current requirements and planar construction which are mass-producible with high reliability. Associated with the conductors constituting the recording elements are one or more selected materials, predeterminably situated, for substantially reducing the reluctance of the magnetic writing circuit associated to the conductor recording zone. The material is arranged to at least partially define the recording zones and to shield the recording medium from the magnetic fields associated to the recording elements outside of the recording zones. Through appropriate choice and placement of such material, a pre-biasing effect may be achieved thus enabling further reduction in recording currents.
