发明名称 MAGNETIC HEAD HAVING SOFT-MAGNETIC MATERIAL CLADDED CORE LIMB FACES
摘要 Magnetic head comprising a magnetic core having two core limbs (1,3) formed from a ferrite, which core limbs constitute two core faces located opposite each other, at least one of said core faces having a cladding of a soft-magnetic material having a higher saturation magnetisation than the ferrite, and a non-magnetic transducing gap (11) present between the core faces and having at least one layer of a first metallic material (21) and bonded layers (23) of a second metallic material. The cladding comprises a first cladding layer (15) of an alloy based on Ni-Fe on which a second cladding layer (17) of an amorphous alloy based on Co-Ti and/or Zr and/or Hf-Nb and/or Ta is provided, while the first metallic material, chosen from the group of Mo, Ti, Cr and NiCr, is directly provided on the amorphous alloy of the cladding. (FIG. 2).
