STABILITY OF STORING INFORMATION IN MEMORY DEVICES ON SOLID THIN FERROMAGNETIC FILMS,
Abstract
Results are presented of an investigation of the effect of digit currents in the adjacent sections of a thin film on the uncalled numbers as a function of the size of both the remagnetized section and the film thickness. It is found that the stability of data storage increases with an increase in the spacing between the axes of digit wires. The most stable are the data recorded on an 85-nm thick film with word wires 0.2-0.4 mm wide, and with the spacing between the axes of digit wires of 1-2 mm. This corresponds to a recording density of 50-100 characters/sq cm. The observed minimum stable domain measured 0.25 x 0.24 mm. Such dimensions corresponds to a recording density of the order of several thousand characters/sq cm. (Author)
