Abstract
A method for forming a magnetic head with two magnetic materials and magnetic heads obtained by this method. According to the present invention, a first magnetic material (72, 74) with slight hardness is electrolytically deposited and a second magnetic material (82, 84) with increased hardness is deposited by any other means, especially by cathodic evaporation. Magnetic heads produced by such a method find application for the reading and storage of information of magnetic media such as disks, tapes, etc.
