Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an optional method for separately recording the OK part of the recording excluding the NG part by inputting an OK or NG signal for the content at the time of recording and reading out the OK or NG signal at the time of playback. Regarding the extraction recording device, for example, recordings recorded on tape in a studio can be edited immediately in a single process without rewinding the tape, making quick editing possible without lowering the S/N ratio. It is an excellent recording device that provides good sound quality.

To describe an example of the implementation of the present invention, as shown in FIG. While recording, move it to the left in the 2' direction and wind it up.
If the recording is OK after one section, press the silent OK button 6 on the panel 5 of the control box to silence the specific frequency.
The OK signal 7 is recorded on the second track B by the head 8. This silent OK signal can be reproduced from track B, but the signal cannot be reproduced from audio track A.

Continue to record the next recorded content 9 on the first track A, and if OK, send the silent OK signal 10 to the second track.
Record on track B. After that, if there is a problem with the talent during the recording, press the NG button 11 to send an OK signal to track B.
An NG signal 12 of a frequency different from that of the NG signal 12 is recorded. Then, the tape 2 stops running. In other words, OK
Recording 9 between signal 10 and NG signal 12 is NG. Next, when the start button 13 is pressed and a start signal 14 is recorded on the second track B, the tape 2 runs again and the next recorded content 15 is recorded on the track A. If the process is OK, the silent OK signal 16 is input, and if the process is NG, the NG signal 17 is input and the start button 14 is pressed, as described above.
Next, if the user presses the OK button 19 for the content 18, an OK signal 20 will be recorded on both track A and track B.

A start button 13, a silent OK button 6, an OK button 19, an NG button 11, etc. are provided on the panel 5 of the control box, and an amplifier 21 and a controller interface 2 are provided.
When the NG button 11 is pressed as described above, the tape running on the tape deck 1 is stopped and the start button 1 is
When 3 is pressed, the tape on tape deck 1 starts running, and when the OK button or silent OK button 14 is pressed, the tape and tape deck continue to run.

When the end button 23 is pressed, an end mark 24 is placed at the end of the tape 2, and the emergency stop button 2 is pressed.
If you press 5, tape 2 will stop running. These specific mechanisms are not particularly illustrated here because they can be made using known techniques.

The arrangement of these operation buttons on the panel is divided into two groups: stop and progress, and the progress group is further divided into two groups, OK and NG, and this OK group is divided into Start, Silent End, and OK. This allows operations to be performed accurately and quickly.

The various signals mentioned above are recorded using specific different frequencies as shown in FIG. 4, and these are read at the time of editing.

FIG. 2 shows an embodiment of the present invention that performs editing.
The tape 2 recorded in FIG. 1 is loaded onto the tape recorder deck 27 without rewinding, the recording and signal are played back, and the tape recorder deck 28 automatically records the tape 2 on the editing tape 31 running in the direction of the arrow 31'. Record and edit. While continuously rewinding tape 2 in the direction of arrow 2'' with deck 27, check the NG signal and OK.
Signals etc. are sent to the reading deck 28 by the head 8', and recorded contents are sent to the reading deck 28 by the head 3'.

When the head 8' reads the silent OK signal or the OK signal of the tape 2, the tape 31 on the tape deck 28 continues to run, and when the head 8' reads the NG signal or the start signal, the tape 31 stops running. As a result, the OK recording 18 up to the start signal 14 of tape 2 is transferred to 35 of the tape 31, and the recording 15 from the start signal 14 to the silent OK signal 16 is moved to 35 of the tape 31.
The NG part inside is not transferred to the tape 31, and the recording 15 from the silent OK signal 16 to the start signal is recorded.
The OK portion of is transferred to 34 of tape 31. Similarly, from start signal 14 to silent OK signal 10
The NG recordings of 9 up to this point are not transferred to the tape 31, and the recordings of 9 and 4 after the silent OK signal 10 are transferred to 32 of the tape 31. In this way, an edited tape 31 is created in which the NG portions of tape 2 are removed and the OK portions are connected.

Since the OK or NG signals are recorded at different frequencies, the playback head 8 reads and selects the different frequencies. For example, if the OK signal is 440 Hz, the motor 33 rotates and the tape 31 runs to continue recording. When it detects an NG signal frequency of 150 hertz, the drive section of the tape deck 28 stops, and the tape does not run and no recording is made.

The OK signal 20 is input to the editing tape 31 as a sound, and is used to signal that the contents of the entire volume have been edited with only OK, and to signal the start of playback.

These tape start, stop, frequency selection mechanisms, etc. are performed using conventional techniques and will not be illustrated or described here.

FIG. 3 shows the heads 3', 8', and
29 and 30 are shown, and as shown in the figure above, OK is applied prior to the recording content playback head (PH) 3'.
A signal reproducing head (OKPH) 8'' and an NG signal reproducing head (NGPH) 8 are arranged, and from the PH
OKPH is placed 8.5cm ahead, and NGPH is
Since it is placed ahead of OKPH at a position of 9.5 cm, the NG signal is the NG head, and the OK
The signal is read at the OK head before the content.
This causes the RT head 29 shown in the lower part of FIG. 3 to record on the tape 31. PH is a monitor head, and EH head is an erase head, and they are placed 4 cm in front of each other. Also, the deviation from the center of the OKPH head on the sending side to the center of the RH head on the receiving side was 3 cm. This deviation is to correct the deviation of the pinch roll and cap stamp when starting and stopping the tape devices 27 and 28, and eliminate any inconvenience.
The example below is an example of values obtained by experimenting with appropriate spacing.

With the above configuration, the feed tape 2
Deck 27 that sends OK and NG signals
I picked it up and received it with Detsuki 28 and said it was OK.
You can select and record the NGs and arrange the OK parts in an orderly manner. The reason why the NG playback head 8' is placed ahead of the playback head 3' is to prevent NG data from being transferred to the tape 31 at all.

As a result, the recorded and wound tape 2 can be automatically edited into the tape 31 without rewinding it, and the edited tape 31 can be played back and used as is without rewinding.
Editing time can be significantly shortened. Note that the mark 34 on the tape 31 indicates the end of the edited recorded content, and the head 30 can input a specific signal.

In this example, three open-reel tape decks 1, 27, and 28 shown in Figs. 1 and 2 were used, but for example, if you use only two cassette decks, you can record program sources such as broadcasts using one cassette deck. , put an OK signal at the end of the content and an NG signal at the end of the commercial, record it, and after the recording is finished, reverse the cassette deck and play it backwards from the end. This output is input to another cassette deck and through the various processes of the present invention described above, a continuous recording of only the contents from which commercials have been automatically removed is obtained on the tape of the second cassette deck.

In this case, it is optional to set one cassette deck at double speed and the second cassette deck at normal speed.

Since the present invention is as described above, it is possible to automatically edit a recording recorded in a studio with only one playback and recording process without having to rewind it.

It is known that in the case of normal recording, the SN decreases by about 5 DB for each dubbing, and while the normal recording method requires dubbing 5 to 6 times, the present invention reduces the SN by 1 DB.
Being able to edit in one go is an invention that can greatly improve the sound quality. In addition, automatic editing in one go greatly speeds up the work and reduces costs.Also, it can be done completely automatically without requiring any acquisition, and a large amount of uniform quality can be produced. This invention has great effects.

The above is an example of implementation, and various other modifications are possible, but all or part of these, the sending position, the receiving device, the device that combines these, the recording/reproducing method, and the recording medium are all included in the present invention. It is.
