ABSTRACT:
A magnetic sensor for use in a reading head for a magnetic disk is formed by depositing a plurality of planar superimposed layers of metals and semiconductors and using for the active element a planar structure formed orthogonal to the superimposed layers by their edges. Specifically, the edges of the superimposed layer form on the orthogonal planar surface a Corbino-disk structure in which conductive regions form inner and outer electrodes about an annular semiconductive region with high magnetoresistance, such as is provided by cadmium mercury telluride or indium antimonide.
