RECORDING SIGNAL CHECKING METHOD FOR VTR

摘要

The method for confirming the record state as automatic rewinding and replaying the just recorded scene comprises steps; (a) checking the after check recording (ACR) pulse; (b) recording and counting for certain time; (c) stopping the record mode after certain time; (d) rewinding the tape and decreasing the counted value with the rotation pulse of a reel sensor (20); (e) stopping the rewind and replaying the tape when the count value comes to zero; (f) analysing the envelope line of the video signal at which the recording mode is continued if the analysis result is well but stop mode is performed and abnormal state is informed through a display (60) if the analysis result is not good.
