Abstract
PURPOSE: To prevent the reproduction error of frame synchronizing signal and to ensure to reproduce the frame synchronizing signal, by the control signal, which has a given relation with the frame synchronizing signal and is recorded and reproduced at a separate location from a digital signal.
CONSTITUTION: The frame F of digital signals 3a, 3b is constituted with digital word groups W1, W2, frame synchronizing signals S1, S2 and S3, S4, and the control signal 3c is recorded on a separate track as the digital signals 3a, 3b on a tape, and this control signal is used for the correction of the mechanism of a recorder. This control signal C is produced from a FF circuit 5d which inputs the 1st and n-th outputs of a 2n notation counter 5b inputting the input clock 5a, and the frame synchronizing signals S1, S2 and S3, S4 are produced from the FF circuit 5e which inputs the p-th and (p+q-1)-th outputs of the counter 5b. Further, the reproduction error of the frame synchronizing signals S1, S2 and S3, S4 is avoided for sure reproduction.
