Abstract

PURPOSE: To realize a low cost for the device which records and reproduces several synchronous signal information on a track, by securing the amplitudelike addition for the time information.
CONSTITUTION: Three different types of synchronous signals (a), (b) and (c) supplied from input terminals 1, 2 and 3 each are controlled through amplitude level adjustment 4, 5 and 6 respectively, and then added together at adder circuit 7 to be recorded on recording medium 9 such as the magnetic sheet or the like via record process circuit 8. The signal supplied from medium 9 is reproduced at reproduction process circuit 10 to obtain reproduced signal waveform (e). Waveform (e) is then set by DC level setters 11, 12 and 13 so that the levels of (e1), (e2) and (e3) may turn to the Schmitt levels of Schmitt circuits 14, 15 and 16. Accordingly, signal waveforms (f), (g) and (h) corresponding to (e1), (e2) and (e3) of waveform (e), i.e. reproduced signal waveforms (a), (b) and (c) are obtained at output terminals 17, 18 and 19 each. In such constitution, the process system of the synchronous signal can be simplified, thus realizing a low cost.
