Multiple- Track Magnetic Heads

The object of this investigation was to devise an economical construction method for multiple-track magnetic heads used in recording on 35mm perforated magnetic film, particularly when such (reproducing) devices are used in a theater for the stereophonic presentation of motion pictures. Two methods of construction were employed. The head built by one method shows somewhat more crosstalk reduction, but the head built by the other method is less expensive to manufacture and also shows a number of other superior features. Both magnetic heads are entirely satisfactory for the purpose intended, in regard to frequency response as well as to sensitivity and crosstalk.
