Abstract

811,160. Magnetic sound records. TOCHIHARA, S. May 25, 1956 [May 28, 1955], No. 16262/56. Class 40 (2). A sound record comprises a carrier sheet 1 having on one side a surface adapted to receive visual information. 2 and on the other side a magnetic sound recording film 3, the latter being surrounded by margins 4 free of magnetic film. Holes, notches or other means 5 are provided in the margins 4 for fixing the sheet in a sound recorder. The sheet may be of paper, plastic, cloth, glass, &c. In use the recorded sheet is fixed and the reproducing head is moved to scan the recorded zone while the operator observes the indication 2 on the recorded sheet.
