Abstract
Magnetic transducing head comprising a magnetic core having two core limbs (1, 3) formed from a ferrite, a non-magnetizable gap (11) extending between two core faces (1B, 3B) of the core limbs and an electric coil (7) passing through a winding aperture (5). A cladding consisting of a first layer (13) of an Ni-Fe-based alloy is provided on at least one of the core faces, and a second layer (15) of an Fe-Si-Al-based alloy which is provided on the first layer.
