Jan. 1947 SOUND RECORDING ON COATED PAPER TAPE 49 MR. KELLOGG: Can you give us an idea of what percentage, either by weight or as metal, and how much plastic it contains after it is dried out? MR. HOWELL: The material is metallic in nature and naturally the magnetic density in the coating will depend on how much of the metal you use. You necessarily have to use a certain amount of bonding material to keep it together and make it adhere to the paper — not more than 10 per cent, ordinarily, if you use a properly chosen material. MR. KELLOGG: Is that by volume or weight? MR. HOWELL: By volume.
