摘要：
The invention pertains to a method for the manufacture of a magnetic head, and a magnetic head in which this method is applied, a method which, after the head is manufactured, provides for a stage for making a mechanically shielding layer of a material such that the bonding coefficient is high, i.e. such that the chemical valencies with respect to the material forming the head is close to one.The invention can be applied in particular, to the manufacture of magnetic heads in thin layers for reading/writing on magnetic tapes.
