Abstract

756,172. Magnetic sound recording or reproducing heads. BRITISH THOMSONHOUSTON CO., Ltd. Nov. 5, 1954 [Nov. 12, 1953], No. 31402/53. Class 40(2) A magnetic sound recording or reproducing head for film sound apparatus, particularly a multiple track head is mounted to pivot freely about an axis which is parallel with the direction of travel of a film 4 having a magnetic sound track or tracks past the non-magnetic gap or gaps, not shown, in the head; the mounting permits the head to follow any twisting movements which may occur in the film while ensuring that the gap(s) remain in contact with the sound track(s). As shown the mounting comprises an ear 2 projecting at one side of the head 1 which ear is freely pivotally mounted in a supporting rod 3 rigidly mounted on the recording or reproducing apparatus.
