A RECORDING CONFIRMABLE METHOD OF VIDEO TAPE RECORDER

摘要

This invention provides the condition of recording for an user. For this purpose we install two recording heads and two reproducing heads in a head drum. The process is as follows. Two recording heads (A)(B) and two reproducing heads (A')(B') have a constant angle and they are on the head drum. A switch makes a video signal transfer from recording heads to reproducing heads, and the detected signal from a reproducing signal inputs the comparator through two reproducing amps(A'P)(B'P) and a switching circuit(SWP). Therefore the condition of VTR's recording is known by a LED in a comparator. This process is illustrated in Fig.1,2.
