摘要 A dubbing apparatus and dubbing method are providing. The dubbing apparatus includes a reproduction drive for reproducing reproduction of a tape recorded by a helical scan system, a recording drive for recording a reproduced signal reproduced by the reproduction drive, a reproduction envelope evaluating unit for evaluating reproduction situations of a reproduced signal corresponding to a signal recorded on the recording drive and a control unit for controlling the number of dubbings conducted by the recording drive 13 and parameters of reproduction conducted by the reproduction drive 11 in response to the reproduction situation evaluated by the reproduction envelope evaluating unit 17. According to these dubbing apparatus and dubbing method, deterioration of image quality of a dubbed image can be relieved even when rectilinearity between reproduced and recorded patterns is shifted upon dubbing.
