Abstract

A data recording system for use in video tape recorders selects one of a plurality of data including position information of a magnetic tape on and from which a video signal is recorded and reproduced by the video tape recorder, and controls the duty cycle of control pulses in accordance with the selected data when recording the control pulses in a control track of the magnetic tape. The data recording system is arranged to add dummy bits to a data block including the control pulses and to change the number of the dummy bits at a predetermined period. The dummy bits are added at the tailing end of the data block following the time code, and the first bit of the dummy bits represents the number of the dummy bits and is disposed in a predetermined position related to the leading bit of the data block. This arrangement corrects the time deviation of the time codes without skipping the contents of the time code data.
