Abstract

PURPOSE:To fill up a blank part generated between recorded parts at the editing of a tape without generating a free running problem by executing insertion recording including a control signal. CONSTITUTION:In the insert mode, insertion recording including a control signal is executed on a tape having the shown blank part 2. Consequently, the shown tape can be obtained. In the figure, the part 8 is an inserted video signal, sound signal, queue signal, or time code signal part and the part 9 is an inserted control signal part. The reproduction of the tape prevents a TV screen from disturbance even when the part 8 is reproduced since the control signal is included.

Conventional structure and problems Conventionally, the only editing modes were the normal recording mode, assemble mode, and insert mode, which is a recording mode using any combination of video signals, audio 1η, time code signals, and cue signals. Ta. In the normal recording mode and the assemble mode, recording is performed using the full-width erase head, so even if you try to fill in the blank area (2) shown in Figure 1 and record, if you stop recording, you will see Figure 2. It will look like this. That is, (4) is the part recorded in m11''1モ recording mode or assemble mode, (
6) is the part that has already been recorded, (5) is the blank part created by the full width erase head, (1) (3)
is the recorded part. The size Al of this blank portion (5) is determined by the tape running speed and the mechanical distance between the head drum and the full width erasing head. Therefore, the blank portion (5) cannot be eliminated.

Also, if you try to fill in the blank part (2) using the insert mode with the tape shown in FIG. 1, the result will be as shown in FIG. 3. In Figure 3, the blank part (8
) has recorded an arbitrary video (+) -υ-, but since control +1- control information cannot be recorded in insert mode, the part that has already been recorded (1) (3
) has the control signal (1), but there is no control information in the part (8). When playing back a tape recorded in this way, there is no running standard for the capstan in part (8), so the tape runs in free run.
