Abstract

PURPOSE: To accurately detect a data heading signal and prevent the increase in the recording density, by recording data starting signals at a data level within one horizontal scanning interval just after a vertical synchronizing interval.
CONSTITUTION: The data starting signals N1WN2 are recorded at the data level in the same pattern within one horizontal scanning interval CiWCi+1. Control signals L1, L2 are recorded between the data starting signals N1WN2. In a reproducing system, the signal N1 is counted by a counter 7 to set a flip-flop 8 and the final bit of the signal N2 is counted 9 to set a flip-flop 10 so that the writing to a shift registers 5 is finished and the writing to a shift register 12 is started. When a predetermined number of bits are written in the register 12, the contents of the resistors 5, 12 are collated 14 with each other. If the contents coincide with each other, a flip- flop 16 is set to send out required information through a gate 17. Thus, the data starting signals can be stably supplied.
