Attorney, Agent or Firm:
A dual video signal simultaneous recording system for a VCR in which two different source video signals are simultaneously recorded on one video tape. The system includes two additional video heads on the head drum each kept within angles of 90.degree. relative to the existing heads. A second video signal is fed to the additional video heads while keeping a predetermined delay period of time interval relative to a first video signal fed to the existing video heads. The system includes a first record system, synchronous separators, a gate array, an analog/digital converter, switches, field memories, a digital/analog converter, and a second record system. The system is also characterized in that the gate array outputs switching control signals, memory control signals, and conversion control signals derived from a head switching signal, a record signal, and synchronous signals. Furthermore, the azimuth angles of the additional video heads are different than the azimuth angles of the existing heads, so that two different source video signals input simultaneously can be recorded on one video tape by one video recorder and player. |

DETAILED DESCRIPTION Therefore, an object of the present invention is to provide a dual video signal simultaneous recording apparatus which is capable of recording simultaneously two different source video signals on one video tape.
The above object of the present invention is attained by such a manner that two more video heads are additionally arranged which are spaced at intervals of 90.
degree.
angles relative to the existing video heads so as to be able to trace the portion which is not yet recorded with a video signal among the track of video tape using a standard mode, and another video signal is supplied to said additionally arranged video heads with a predetermined delay time relative to the video signal supplied to the existing video heads.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter.
However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
