Abstract

A non-destructive readout device may be constructed using the so called Isotropic thin magnetic films. These films are unoriented, i. e., they do not exhibit an easy direction of magnetization. There is shown a structure depicting the device described. The apparatus comprises the Isotropic film 1 provided with X and Y windings.

Non-Destructive Readout Device Using Isotropic Thin Magnetic Films

A non-destructive readout device may be constructed using the so called Isotropic thin magnetic films. These films are unoriented, i. e., they do not exhibit an easy direction of magnetization. There is shown a structure depicting the device described. The apparatus comprises the Isotropic film 1 provided with X and Y windings.

The magnetization may be set with either of the two windings, or by a coincident operation of both windings. After the magnetization is stored in the film, a small read signal is applied of insufficient magnitude to switch the film. After this signal is removed, an output voltage is obtained on the sense winding (either X or Y) without destroying the stored magnetization.
