That is, 10' is the recording medium, 1)' is the trunk,
12' is the video channel, 13' is the audio L channel,
14' is the audio R channel. In the system of FIG. 4, an information signal is recorded on the video channel 12'.

That is, information is encoded and recorded in the form of an analog video signal in the video signal recording unit excluding horizontal and vertical synchronization signals, burst signals, etc.

An information processing device (hereinafter referred to as information processing device A) that reads an information signal from a recording medium recorded by recording method A reads the information signal from the audio R channel 14 into the information processing device A by a known reading process. Perform the desired processing.

On the other hand, an information processing device that reads information signals from a recording medium recorded by recording method B (under J/I, information is referred to as processing device B) uses a known reading process different from recording method A to read video channel 12. The information signal is read into the information processing device B from ', and the desired processing is performed.

In this way, conventionally, when the information recording method differs, the processing for reading the Jikou U signal also differs, so it is necessary to use an information processing device that has a reading method compatible with each information recording method. there were.

For this reason, in the past, two types of recording media were created in which information signals were recorded using two recording methods, one recording method and one recording method B, so that the information processing apparatus could be either A or B. Furthermore, if possible, two types of information processing devices, A and B, were provided.

Note that in each of the cases of recording method 2 and B, it is not necessary to understand the specific contents of the reading process of the information signals in connection with the invention of the present application, so the explanation thereof will be omitted.

[Problem that the invention seeks to solve]

In the conventional information recording system, even if the recording medium that provides information to the two types of information processing devices A and B is the same as described above, the recording method for the information processing devices A and B is different. In order to be able to provide information using the same method, it was necessary to prepare two types of recording media with recording methods A and B for each piece of information. For this reason,
There are problems in that the cost is twice as high as in the case of manufacturing one type of recording medium, and the efficiency of use of the recording medium is also reduced. Furthermore, having two types of information processing devices, A and B, is extremely inconvenient in terms of cost, usage efficiency, space, etc.

[Purpose of the invention]

The present invention was made in order to eliminate the above-mentioned problems in conventional information recording systems, and is an information recording system that can provide information to both information processing apparatuses A and B at low cost using one type of recording medium. The purpose is to realize the following.
