Abstract
To facilitate the introduction of magnetic recording on 35-mm film, modifications have been engineered for adapting photographic recording and reproducing systems so that they may be used alternatively for either photographic or magnetic recording. Existing transmission systems employed in photographic recording have been modified to include a bias-erase oscillator. Magnetic heads have been added to the film recorders in such a manner still to permit the use of the recorder for photographic recording. Re-recorders have been modified for magnetic only or for alternative magnetic or photographic reproduction. The existing photocell amplifier has been modified for the dual reproducing facilities.
