Abstract

875,260. Magnetic recording. MERRITT, L. F. Sept. 15, 1959 [Sept. 18, 1958], No. 29835/58. Drawings to Specification. Class 40 (2). A spool carries at one end a white disc engraved with graduations to correspond with the graduations on a tape position indicator on the machine. The disc is of a material such as ivorene, which may be marked with pencil to indicate the positions on the tape at which particular recordings occur, and from which marks previously made may be easily erased.
