A METHOD FOR COATING MADDIDA MAGNETIC MEMORY DRUMS,

Abstract

A technique was developed for applying a smooth coating of a magnetic dispersion to an aluminum drum used as a magnetic memory for a maddida unit. The finished unit is free from flaws such as 'alligatoring' and has a coating thick enough to give a 0.7 volt a.c. electrical output when the recording is made with a 300 turn winding recording head and a 50 ma. d.c. input current.
