Time-Base Errors and Their Correction in Magnetic Television Recorders
1961
During the recording process in a magnetic TV-recording system, the time relationships of the various parts of the signal waveform are transferred to the recording medium in elements of space. This operation, and the inverse, which occurs on reproduction, may cause undesirable time-displacement errors in the reproduced picture. The factors influencing these errors are outlined and discussed. Methods of reducing the errors and of increasing the time stability of the output signals by electromechanical and electronic means are described.
