Abstract

A magnetic transducer structure is formed of a stack of individually shaped thin layers or films on a dielectric non-magnetic substrate. The stack comprises near or at the outer surfaces thereof a pair of identically shaped magnetic layers spaced apart at an airgap end by portions of intervening insulating layers and contacting each other at the rear ends thereof. The intervening insulating layers together constitute a flat helix the turns of which surround the contacting portions of said magnetic layers and conductor layers in turn intervene between the insulating layers for developing a conductive flat helix embedded within the insulating helix. The turns of the insulating flat helix are registering and the turns of the conductor flat helix are registering. The insulating layers as well as the conductor layers are obtained by vapor deposition through a minimum number of perforated screens or masks which are repetitively used to form additional turns of the flat helices.
