Method of manufacturing a multilayer structure, in which method gold is deposited on a basic layer (3, 11) for forming a gold layer (7, 13), whereafter aluminium oxide is deposited on the gold layer for forming an aluminium oxide layer (9, 15). Silicon oxide is deposited on the aluminium oxide layer by means of PE-CVD for forming a silicon oxide layer (11, 13), and the aluminium oxide layer constitutes an adhesive layer between the gold layer and the silicon oxide layer. Together with the aluminium oxide layer, the silicon oxide layer constitutes an insulating and/or protective cladding layer for the gold layer.

Method of manufacturing a body having a structure of layers

Method of manufacturing a magnetic head, in which a transducing structure (1) comprising at least a transducing element (5) is formed on a substrate (3) by means of a thin-film technique, after which a thick film coating (23) is provided on an uneven surface (21), remote from the substrate, of the structure formed. The thick film has a thickness which is minimally equal to the distance between an area (21A) of said surface which is farthest remote from the substrate and an area (21B) which is most proximate to the substrate and is deposited on said surface by means of PE-CVD.
