Abstract

(57) [Summary] [Purpose] The object is to provide an image signal recording and reproducing device that allows the content of recorded image signals to be confirmed without rewinding the magnetic tape. [Structure] An image signal recording and reproducing apparatus that records an image signal on a magnetic tape and reproduces the image signal recorded on the magnetic tape includes a recording drum equipped with a recording magnetic head and a reproducing magnetic head. loading the same magnetic tape onto the recording drum and the reproducing drum, recording image signals on the magnetic tape with the recording drum, and recording on the magnetic tape with the reproducing drum; The system is configured to reproduce the image signal that has been generated.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention records an image signal on a magnetic tape, and the image recorded on the magnetic tape. The present invention relates to an image signal recording and reproducing device that reproduces signals.

0002

[Conventional technology]

Conventional image signal recording and reproducing devices check the contents of image signals recorded on magnetic tape. To do this, after recording has finished, rewind the magnetic tape to the position where recording of the image signal started. However, this was done by putting the device in a regeneration state and performing a regeneration operation.

0003

[Problem that the invention is trying to solve]

However, conventional image signal recording and reproducing devices wind magnetic tape as described above. If you do not return it, you will not be able to check the contents of the recorded image signal, which will complicate the operation. , it is not possible to instantly check the contents of the recorded image signal, making it very inconvenient to use. It was a good thing.

0004 This invention allows you to check the contents of recorded image signals without rewinding the magnetic tape. The purpose of the present invention is to provide an image signal recording and reproducing device that can perform the following functions.

[0005]

[Means to solve the problem]

The image signal recording and reproducing device of the present invention records an image signal on a magnetic tape, and A device that reproduces image signals recorded on a disc and is equipped with a recording magnetic head. and a reproducing drum equipped with a reproducing magnetic head. The same magnetic tape is loaded on the recording drum and the playback drum, and An image signal is recorded on a magnetic tape by a drum, and the image signal is transferred to the magnetic tape by a playback drum. It is configured to reproduce image signals recorded on a tape.

[0006]

[Effect] According to the above configuration, the contents of the recorded image signal can be read without rewinding the magnetic tape. You will be able to check.

[0007]

【Example】

Hereinafter, the present invention will be explained using examples of the present invention.

[0008] FIG. 1 is a block diagram of an image signal recording and reproducing apparatus as an embodiment of the present invention.

[0009] In FIG. 1, when a tape cassette 6 with a magnetic tape 7 is loaded into the device, , prior to the recording operation, the magnetic tape 7 in the tape cassette 6 is loaded with tape. The tape is pulled out from inside the tape cassette 6 by the tape cassette 6 and has the magnetic heads 4 and 5. It is wound around a recording drum 3 having magnetic heads 10 and a reproducing drum 9 having magnetic heads 10 and 11. As a result, the magnetic tape 7 is loaded.

0010 Then, by operating an operation unit (not shown), image signals are recorded on the magnetic tape. When the simultaneous recording and playback mode is specified, in which the content of the issue is simultaneously monitored while being recorded, the magnetic The tape 7 is run in the direction of A in the figure by a capstan and a pinch roller (not shown). At the same time, the recording drum 3 and the reproducing drum 9 are rotated, and the image signal input terminal The image signal input from the child 1 is processed into a signal for recording in the recording signal processing circuit 2. After being processed, it is supplied to the magnetic heads 4 and 5 attached to the recording drum 3. The data is recorded on a helical track (not shown) on the magnetic tape 7.

[0011] As shown in the figure, the magnetic tape 7 is wound around a reproduction drum 9. The magnetic heads 10 and 11 attached to the raw drum 9 cause the magnetic tape to be The image signal recorded on the helical track on 7 is reproduced, and the reproduced signal processing circuit 1 2 and is supplied to the recording signal processing circuit 2 in the reproduction signal processing circuit 12. After signal processing that is opposite to the processing performed by The content of the image signal recorded on the magnetic tape by supplying it to a monitor device, etc. You will be able to record and check at the same time.

0012 Note that there is no need to check the contents of image signals recorded on magnetic tape at the same time as recording. (not shown) when playing back a magnetic tape on which image signals have already been recorded. By operating the operation panel and instructing the recording mode or playback mode, Drum 3 and recording signal processing circuit 2, or reproduction drum 9 and reproduction signal processing circuit It is also possible to perform normal recording or reproducing operations using the respective channels 12. Ru.

[0013] As explained above, according to the configuration shown in this embodiment, the magnetic tape can be rewound. It becomes possible to check the contents of the recorded image signal without having to do so.

[0014]

[Effect of the idea]

As explained above, according to the present invention, it is possible to record without rewinding the magnetic tape. It is possible to provide an image signal recording and reproducing device that can check the contents of an image signal. It will look like this.
