Claims

[Scope of utility model registration request]

(1) In a video tape recorder in which a recording and reproducing head records log signals on a magnetic tape that has been erased by an erasing head, a recording mode in which the erasing head and recording head are simultaneously operated is used. 1. A video tape recorder comprising means for continuing the operation of said recording/reproducing head for a predetermined period of time even after said erasing head is stopped when transitioning to a mode.

(2) The video recorder according to claim 1, wherein the luminance signal, color signature, and audio signal of the recording current supplied to the recording/reproducing head are kept constant during the predetermined period of time. .

(3) The video tape recorder according to claim 2, which is a registered utility model, characterized in that the constant levels of the luminance signal, color signal, and audio signal are variable.
