ABSTRACT:
A video tape recorder capable of recording a normal definition video signal and a high definition video signal having an image quality higher than the normal one in a simulcast for broadcasting an identical program in a conventional broadcasting system and a high definition system. The common video signal is recorded in a conventional analog signal format at a tape feeding speed of the normal mode by an EP mode head defining a tracking width narrower than that of a standard mode head, while the high definition video signal is recorded in a digital form by a high definition video head additionally mounted on a rotary drum. Additionally, a common video signal recorded by a conventional video tape recorder can be reproduced.
