Title: Improvements in or relating to magnetic record member
IPC: G11B11/10
Filed: 1953-03-16
Abstract: 774,487. Television. ARMOUR RESEARCH FOUNDATION OF ILLINOIS INSTITUTE OF TECHNOLOGY. March 16, 1953 [April 11, 1952], No. 13217/54. Divided out of 774,485. Drawings to Specification. Class 40 (3). A magnetic tape carries video information in transverse lines of magnetization, the field of each line being offset from but merging with the field of the next adjacent line in the longitudinal direction, the lines extending right across the tape or being in two or more groups of lines each occupying part of the width of the tape. This is achieved by so adjusting the speed of the tape when recording and the thickness of the lamination of the recording transducer that the field of one line as it is recorded on the tape modifies the field of the preceding line. The advantage is that a signal will be picked up even if the playback head scans between the lines of magnetization. An audio round track may run along one side of the tape. The lines of magnetization may be straight or curved and there may be three groups of lines spaced across the width of the tape. The tape may have sprocket holes for synchronizing the speed of the tape with the recorded signal. The recorded fields of each line also overlap one another in the transverse direction. Specification 774,486 is referred to.
