Abstract
A method of producing a thin-film magnetic head on a carrier (1) comprising depositing an electrically conducting plating-base (2) and electroplating flux conductors (4a, 4b) and a magnetically insulating layer (8) on the plating-base. This provides a planar structure on which an electrically insulating layer (9) and a magneto-resistance element (10) are applied. The plating-base (2) also constitutes the gap layer.
