MAGNETIC FILM MEMORY EVAPORATION SYSTEM
Abstract
The system facilitates the deposition of large area magnetic film memories and the observation of wall coercive force during an annealing cycle. It provides for sixteen substrates 1.6 inches wide by up to thirty inches in length to be sequentially coated. Three induction heated sources are employed containing up to one pound of melt in each crucible plus additional resistance heated sources for the evaporation of a chromium underlayer which enhances adhesion of the magnetic film to the substrates.
