Verfahren zum Herstellen eines Magnetkopfes und Magnetkopfgruppe hergestellt nach diesem Verfahren

摘要

A method of manufacturing one or more magnetic heads starts from a substrate (11) on which a first magnetic layer (13) is provided. A recess (15) is formed in this layer at the location of a transducing gap to be formed, after which a gap layer (19) is provided on a bounding wall (17) of the recess. Subsequently, the recess is filled with a second magnetic layer (23) and a counterblock (31) is provided on the layers after surface-polishing. Finally, a winding aperture is provided.
