Magnetic transducing head having clad core faces - has non-magnetisable gap extending between core faces and coil passing through winding aperture

摘要

The magnetic transducing head comprises a magnetic core having two core limbs formed from a ferrite. The core limbs have two faces facing each other with at least one provided with a cladding consisting of a layer of an Fe-Si-Al-based alloy. A non-magnetisable transducing gap extends between the core faces. A winding aperture with an electric coil passing through is provided around a core limb. The cladding also comprises a layer of an Ni-Fe-based alloy which is provided on the core face while the layer of an FE-Si-Al based alloy is provided on the layer of Ni-Fe-based alloy. The width of the central core face parts is at least equal to the width of the gap boundary faces.
