ABSTRACT:
A video tape recorder (VTR) adapted for use in editing tapes so that a second signal may be recorded on the tape to accurately and closely follow a first signal recorded thereon is provided with a record review mode where a portion of the first recorded signal immediately preceding the changeover, or edit, point may be reviewed prior to recording the second signal. The VTR is of the type which, upon being placed in a pause mode, automatically rewinds the tape by a length corresponding to a first predetermined number of control signals. In the VTR according to the present invention, upon entering the review mode, the tape is automatically rewound for a second length and then played back for a third length corresponding to but slightly less than the sum of the first and second lengths. Thereafter, the VTR automatically reenters the pause mode to be rewound again by the first predetermined length.
