Abstract
Various types of a-c magnetic erase heads of the ring-shaped type are described. After a brief mathematical treatment of the magnetic flux density required for erasing, there are given the measurements of the amount of erasure obtained with various heads used both singly and in cascade. Also included are curves showing the rise in temperature on part of two heads as a function of the 70-kc erase-current through the head.
