Abstract

685,109. Recording-apparatus. STANDARD TELEPHONES & CABLES, Ltd. Oct. 22, 1948, No. 22819/51. Divided out of 685,032, [Group XL (b)]. Class 106 (iv). [Also in Group XL (b)] In a method for recording signals comprising code signal elements of opposite polarities on a magnetizable tape or wire, the elements are recorded without any spacing therebetween and at such strength as to produce magnetic saturation of the recording medium so that a fresh set of signals can be recorded over or upon existing signals without having recourse to a " wipeout " or erasing operation.
