ABSTRACT:
An apparatus for generating a recording time code signal having a time code data signal generator and a time code signal forming circuit which is supplied with a time code data signal from the time code data signal generator and produces a recording time code signal consisting of bi-phase coded signals, in which the above recording time code signal is corresponded to an information signal and then recorded on a recording medium continuously at word unit. In this case, the polarity of a specific bit signal of a fixed binary bit or value in the above recording time code signal of word unit is discriminated, and a changing circuit is provided in the time code signal forming circuit which changing circuit changes the above fixed binary bit in accordance with the polarity of the specific bit signal. Thus, a recording time code signal of word unit, which has a constant polarity of bit signals after the above specific bit signal, is derived from the time code signal forming circuit.
