Conventionally, in a recording device using a rotating magnetic recording medium, when recording a large number of still images, the first
As shown in the figure, recording is performed concentrically on a so-called magnetic disk MD, and for convenience of use, for example, A, B, C, etc. are recorded from the outside.
Each track is recorded with a code such as 1, 2, 3, etc. This can be done by mechanically detecting and displaying the position of the recording magnetic head H, as shown in Figure 2a, or by using an electric circuit linked to the feeding mechanism of the magnetic head H, as shown in Figure 2b. Therefore, the position of the head H is detected and the track on which the head H is located is displayed.
しかしながら、かかる従来方式にあつてはテレ
ビジヨン放送画像等の既製画面を録画するときは
余り支障ないがカメラを用いて録画するときには
その都度毎にカメラのフアインダーから目を離し

用上極めて不便であつた。
However, with this conventional method, there is not much trouble when recording ready-made screens such as television broadcast images, but when recording with a camera, it is necessary to take your eyes off the camera's viewfinder and check the track number each time. This was extremely inconvenient in practice.
そこでこの考案は以上のような点に鑑みてなさ

を目的とする。
Therefore, this idea was made in consideration of the above points. For example, it is possible to check the track number while looking at the subject through the camera's viewfinder, and it is also possible to record the track number at the same time as the image signal from the camera. By doing so, it is an object of the present invention to provide an extremely good recording device that can simplify and reliably eliminate the above-mentioned conventional drawbacks.
またトラツク番号と一緒に、日時等、画像信号

に使い勝手を向上させることを目的とする。 It is also intended to further improve usability by recording and displaying data related to the image signal, such as date and time, along with the track number.
この考案は上記の事情に対処すべくなされたも

This idea was made to deal with the above situation, and the date and time etc. can be added to the truck number signal as necessary.
Signals related to the image to be recorded are added to form a track number information signal, the information is displayed on the camera section, and the information signal is recorded on the rotating magnetic recording medium at the same time as the image signal from the camera. In this way, the above objectives are achieved.
以下図面を参照してこの考案の一実施例につき

An embodiment of this invention will be described in detail below with reference to the drawings.

て日時等の他のデータも文字発生回路１２により
発生させて、トラツク番号信号と同時に情報信号
として記録かつ表示することも容易にできるから
この方式は極めて有用である。 That is, as shown in Figure 3, the magnetic disk
A track number signal obtained from a track number detector 11 which detects the track number from the MD through the head H feeding mechanism is supplied to a character generating circuit 12. Then, the numerical image signal of the track number generated here is applied to the recording amplifier circuit 13 together with the video signal supplied from the camera, and is recorded from there on the magnetic disk MD via the head H.
The reproduced signal from the head H is led out to a predetermined section via the regenerative amplifier 14, and in other words, it is reproduced on the viewfinder of the camera section for monitoring as shown in Figure 5a. In this case, the track number TN displayed at the upper right corner of the screen can be viewed at the same time as the object image O. However, this method has the advantage that the track number can be displayed on the screen even when a magnetic disk reproducing device that does not have a track number display function is used. Furthermore, this system is extremely useful since it is possible to easily generate other data such as date and time in addition to the track number by the character generating circuit 12, and record and display it as an information signal at the same time as the track number signal.

同時に監視するためのものである。 FIG. 4 shows another embodiment, in which a signal from the track number detector 11 similar to that described above is converted into a pulse signal by a track signal circuit 22, and its pulse signal is applied to the video input signal. The pulse signal is applied during the ranking period, and is subsequently recorded through the recording amplifier 13 in the same manner as in the previous example. During reproduction, a track signal separator 25 separates a track number signal from the reproduced signal that has passed through the regenerative amplifier 14, and displays this on a track number display 26 using a display element such as a liquid crystal or a light emitting diode. However, in the case of this method, the track number TN can be displayed off-screen without displaying any distracting numbers on the screen, as shown in Figure 5b, and it is easier to implement than the previous method, especially when the track number is needed during playback. The frame can be automatically selected from the signals from the track signal separator 25, which is extremely useful. That is, in this case, the means for inputting the track number signal may be used to compare this track number signal with the reproduced track number signal, and the position of the head H may be controlled based on the comparison output. The track number display 27 in the figure is for monitoring the display of the track number and the recorded image at the same time.
なお、この実施例の場合も、トラツク信号回路
２２で、日時等の信号を発生させてトラツク番号
と一緒に記録し、同時にそれらを表示することが
できる。 In this embodiment as well, the track signal circuit 22 can generate signals such as date and time, record them together with the track number, and display them at the same time.
この考案によればトラツク番号および日時等の
情報を表示するのに電気信号を用いているので、
使用ケーブル長にも制限がなく、特に３回線、４
回線の構成ではケーブル芯線を増す必要もなく、
簡便且つ安価に実施し得るという利点を有してい

およびその近傍のみに限らずカメラ外部でもよい
如く任意な位置をとり得るものである。
According to this invention, electrical signals are used to display information such as truck number and date and time.
There is no limit to the length of the cable used, especially for 3 lines and 4 lines.
There is no need to increase the number of cable cores in the line configuration.
It has the advantage of being simple and inexpensive to implement. In this case, the track number, date and time, etc. can be inserted into the recording screen, and the display position is not limited to within and near the camera screen, but can also be displayed at any arbitrary position, such as outside the camera.

ツクをランダムに自由に選択できるものである。 Furthermore, in addition to the above-mentioned effects, this invention also has the effect of making it easier to position the head during image reproduction. That is, in this type of recording, the interval between recording bands is usually about 50 μm, and it is not easy to position the head on a desired track. However, according to the invention of the present application, since the head position, that is, the track number, is displayed, it is possible to easily select and reproduce the desired track. In addition, during recording, the track to be recorded can be freely selected at random.
また記録されているトラツク番号を再生して目
的のトラツクを自動的に選択することもできる。 It is also possible to automatically select a desired track by reproducing recorded track numbers.
さらにまた、日時等のデータも記録されるため
再生時に極めて便利である。 Furthermore, data such as date and time are also recorded, which is extremely convenient during playback.
