Abstract

861,129. Magnetic recording apparatus. LEVIN, S. June 4, 1957, No. 17724/57. Addition to 769,761. Class 40 (2). The apparatus and method for recording signals on a stress-sensitive magnetic medium according to the parent Specification are modified by the use, in place of or in conjunction with the magnetic field, of an electric conditioning field in a conductive magnetic tape the required magnetization is induced by the current derived from a steady field, while in a ceramic ferrite or other non-conductive tape it is induced by the local currents arising from an alternating or pulsating field.
