Abstract
The invention teaches that if a "shorted" electrically conductive turn--deposited on a magnetic substrate--is employed to sense recorded signal flux, then the underlying substrate will efficiently support flux induced about the shorted turn . . . and such induced flux will correspond proportionately to the recorded signal flux. In accordance with the invention, an MR element is so situated that it senses induced flux about the shorted turn at a location thereof that is remote from the medium whose signal flux is to be reproduced.
