Read/write coaxial magnetic head for use with apparatus for measuring the surface of superconductors

摘要

A read/write head particularly suitable for mapping the superconductive properties of a sample of superconducting material. The head is arranged so that the reading and writing gaps are coaxial. Although the gaps are coaxial, the reading gap and the writing gap may be optimized in length and width to provide efficient reading and writing performance. The coaxial disposition of the heads eliminates parallax error to permit detailed mapping of the properties of the surface of a sample of superconductive material.
