A New Wire Recorder Head Design
T. H. Long · Transactions of the American Institute of Electrical Engineers · 1946
Certain defects inherent in the usual design of wire recorder heads are pointed out. Some defects are of a practical nature and one is based on theoretical considerations. An improved design is proposed on which a limited amount of experience has been obtained. A natural modificaton of this design permits level-winding across the record-playback head, thus distributing the war and resulting in a head that is virtually self cleaning.
