Abstract
The stored flux level in a 50 percent Ni-Fe tape core is read nondestructively to provide an analog memory. The stored flux level is set by means of a low-field (H < 2H_{c}) pulse. This flux level can be read out nondestructively by applying a short high-field pulse (H > 4H_{c}) which produces a peak rate of change of flux proportional to the stored flux level relative to saturation remanence. A subcoercive bias field applied to the core restores it to the original low-field flux state. Experimental data and the model leading to the conception of the memory are presented; and the circuit details of a typical core analog memory are described.Keywords
