CONSTITUTION:The first audio information, which are English, for example, is recorded to the first sound track 12 of an information recording medium 11 and the second audio information, which is correspondent translation, is recorded to a second sound track 13 respectively. Namely, the second audio information is recorded to the second sound track 13 in the reverse direction of the time flowing direction of the first audio information so that the time position relation can be coincident to the correspondent block of the first audio information. Thus, the information recording medium can be easily obtained.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an information recording medium, such as translation of first information, etc. If the first information is recorded in the opposite direction, the first information is played back by an audio tape recorder with an auto-reverse function, and then the second information is played back by reversing the playback track, the first information This is useful when creating an information recording medium on which second information corresponding to the second information is reproduced.

<Prior Art> For example, it is convenient to listen to an explanation corresponding to a portion of music recorded on a cassette tape.

It would be convenient if the user could hear second information that corresponds to a portion of the continuous first information.

In this case, the first information can be English news, and the second information can be a Japanese translation or commentary corresponding to a part of the English news, and these two types of information are useful when combined as described above. There are many pieces of information in one set.

Therefore, the inventor of the present invention previously proposed an information recording medium in which information corresponding to a portion of continuous information is recorded (see Japanese Patent Application No. 62-28299). This information recording medium has the following configuration.

FIG. 16 is an explanatory diagram conceptually showing the recording surface of a cassette tape when the information recording medium is implemented as a cassette tape. In the figure, 1 is a cassette tape, 2 is an A track, and 3 is a B track. Music, which is continuous information, is recorded on A track 2. In the example, this music is the first information. B track 3 includes each block A-1 consisting of an arbitrary period that is a part of the music.
, 'A-fj IA-3'IA-4' ” Explanations corresponding to A-15 are recorded. In this example,
This explanation is the second information. At this time, B track 3
Each block with an explanation recorded in--1# ■a-
su Ie-s.

I and I are the blocks I to which these correspond, respectively.
~I, the temporal positional relationship is almost the same, and the direction opposite to the temporal flow direction of the music is the normal flow direction of information during playback. Therefore, each block I
Starting points of A-1 to IA-8 and each block 1. -3~l6-
6, and the end points of each block IA-1 to ■A-6 and each block ■3-8 to 1. -2 almost coincides with the starting point.

The starting point of block lA (IA-1~!1-1 is the position where the middle of the music corresponding to each commentary begins, and the end point of the same block!) is the position where the middle of the music corresponding to each commentary ends. It's the location.

Furthermore, block! . (lI!-1~■.-1 start point and end point are the positions where each explanation starts and ends.

In this way, in the A track 2, music, which is the first information, is recorded continuously without being interrupted by the block lA, but in the B track 3, the commentary, which is the second information, is recorded in the adjacent block. They are recorded discontinuously through spaces between 13. Just block! If the number of , increases and the space becomes smaller, the second information can also be effectively regarded as continuous information.

The suffix added to 1 in Figure 16 corresponds to blocks with matching numbers, and the suffix added to the right side of the figure for I means that information is recorded from the left to the right, and the suffix is added to the left side. The dotted lines indicate that information is recorded from the right side to the left side.

Therefore, music is normally reproduced when the cassette tape 1 moves to the left in the figure relative to the magnetic head, and when the cassette tape 1 moves to the right in the figure relative to the magnetic head.

Such a cassette tape 1 is a cassette tape recorder having an auto-reverse function, and the block 1. -1~1. -1 and the middle of the music recorded in blocks A-1 to IA-4 corresponding to blocks I&-3 to Ia-s, respectively, can be listened to alternately.

For example, block! After listening to the explanation of , -3, if you want to listen to the music of block ■, -3 corresponding to that part, play the B track 3 to block! , -2, and when the explanation is finished, operate the reverse key to select A.
Switch to playback of track 2. This results in block IA
The music is played from the starting point of -2, and the music corresponding to the explanation of block I can be heard.

At this time, if the reverse key is operated again at the end of block IA-1, the explanation of blocks 'b-Q can be heard again.

Other blocks l6-1. 'After listening to the explanation of 6-3~■,-5, select the blocks I, 1~■A- corresponding to each part.
If you want to listen to music No. 6, you can do the same operation as above.

Of course, it is also possible to operate the auto-reverse key while listening to music, and this is useful when searching for explanations that correspond to the middle of the music, and also when listening to music. This is useful when the operator remembers whether a position has an explanation.

In the above example, a combination of the first information, which is music, and the second information, which is a commentary corresponding to the music, has been described, but there is no particular limitation on this combination. It is sufficient if the first information is continuous information and the second information is information consisting of a plurality of mutually independent blocks corresponding to a portion of the first information. For example, the case where the first information is English news and the second information is an explanation or translation of the English news, the first information is the audio of a foreign movie, and the second information is the translation, etc. can be cited as the other side. Can be done.

<Problems to be solved by the invention> As mentioned above, it would be convenient to have an information recording medium that combines the first information and the second information, as shown in FIG. It would be more convenient if there were an information recording medium such as a source and a mother tape that can easily create such an information recording medium.

In view of the above problems, an object of the present invention is to provide an information recording medium that is useful when creating an information recording medium having first information and second information as shown in FIG. shall be.

Means for Solving the Problems> The configuration of the present invention to achieve the above object includes translation of a block consisting of an arbitrary section that is a part of the first information, etc.
The second information, which is the information corresponding to this block, is
in the opposite direction to the temporal flow direction of the first information so that the starting point of the block formed from the second information corresponds to the ending point of the first information block. The recorded information and the video information on the video track are
In addition, in an information recording medium in which first audio information corresponding to the video information is recorded in a first audio track, translation of a block consisting of an arbitrary section that is a part of the first audio information, etc. The corresponding second audio information is recorded on the second audio track so that the temporal positional relationship matches the corresponding block, and in a direction opposite to the temporal flow direction of the first audio information. It is characterized by

Function> In the present invention having the above configuration, the direction of the temporal flow of the first information is adjusted so that the starting point position of the block formed by the second information matches the ending point position of the block of the first information. If the information recording medium on which the second information is recorded in the reverse direction is played back and broadcast as the 11 audio of a multiplex broadcasting television digital camera system, for example, it will be possible to play back the information recording medium on which the second information has been recorded in the reverse direction. By recording the reproduced sound of the information recording medium on the audio track of
6. An information recording medium, which is a videotape, recorded in the form shown in FIG. 6 is obtained.

Furthermore, an information recording medium such as a video tape as described above is played back, and the main audio and sub audio are recorded as A of one audio tape.
The information recording medium shown in FIG. 16 can be easily obtained by recording on each of the eight tracks.

Example of implementation Embodiments of the present invention will be described in detail below based on the drawings.

First, the types of first information, second information, and noise information necessary to create the information recording medium according to this embodiment are defined.

When the first and second information is reproduced, the flow direction of the information that is normally reproduced as information is from left to right.H
(Head) - E (End), E when the direction is from right to left
(end)←H (head), and each block of first and second information is the first and second block along the direction from H to E.
When the information of
,3. -n, the same applies hereinafter), and when they are arranged in opposite directions, they are represented as nA and nB. and H, E and An.

By combining Bn, nA, and nB, the first and second information blocks are arranged as HAnE, HnAE, EnAH
.

EAnH, HBnE, HnBE, EnBH, E
Expressed as BnH.

That is, each block IA-1 of the first information shown in FIG.
~'A-6 for example 5TAR, 5NOW, RAIN,
MOON.

Assuming the English audio information WIND (in reality, each block consists of a - sentence or a group of sentences, but here we will consider it in terms of words for simplicity), these are the corresponding translations. Each block Ia of the second information
-t～■a-a is hoshi, yuki, awe,
tsuki, kaze, and if these are illustrated according to the above definitions, the result will be as shown in FIG.

On the other hand, the noise information is for each block 'A-1~ of the first information.
This information indicates the position of the end point of IA-15, and when expressed in correspondence with the first and second information, HNnE,
HnNE, EnNH, ENnH. However, since noise information is essentially meaningless information, there is no need to distinguish between the case of H4H and the case of E←H. Therefore, HNnE - EnNH, HnNE = ENnH, and if these are illustrated, the third The result will be as shown in the figure.

The first embodiment of the present invention can be expressed as follows using the types defined above.

As shown in FIG. 1, on the first audio track 12 of the video tape 11, which is the information recording medium according to the present embodiment, first audio information in English, for example, is recorded as type 1 (AnE) and as second audio information. For example, second audio information, which is a translation corresponding to each of the English words, is recorded as type EnBH together with the video signal of the video track 14. That is, the second audio information is the same as the first one. The second audio track 13 consists of blocks in which audio information corresponding to each block is recorded, such as a translation of each block that is a part of the audio information of The second audio information is recorded in the opposite direction to the temporal flow direction of the first audio information so that the positional relationship matches.As a result of (B), the beginning of each block of the first information ( (left end in the figure) and end (right end in the figure) and the end and start end of each block of second information almost coincide. If we consider that a foreign movie with Japanese lines is recorded, this would be a suitable example.

When such a videotape 11 is played back by a playback device compatible with audio multiplexing, the first information is played back as the main audio type HAnE, and the second information is played back as the sub audio type EnBH. Therefore, by simultaneously recording both the main and sub-audio onto an audio tape, the cassette tape 1 shown in FIG. 16 can be easily created.

The second embodiment of the present invention can be expressed as follows using the types defined as shown in FIG.

That is, as shown in FIG. 2, in this embodiment, second information is recorded as a type EnBH on an information recording medium, for example, a magnetic tape 15. That is, the magnetic tape 15 is arranged so that the starting point position of the block formed of the second information corresponds to each block of the first information almost coincides with the ending point position of the block of the first information. The second information is recorded in a direction opposite to the temporal flow of the first information.

If such a magnetic tape 15 is reproduced and broadcast as sub-audio in a multiplex broadcast television system, for example, a video on which first information has been recorded in advance on the first audio track 12 (see FIG. 1) will be produced as the main audio. The second information of type EnBH can be easily recorded on the second audio track 13 (see FIG. 1) of the tape 11 (see FIG. 1). As a result,
First and second audio tracks 12 of videotape 11.
11, first and second information are recorded as HAnE and EnBH.

In addition, when listening to the first or second information and then hearing the second or first information, it is sufficient that the end point of the block of information on the negative side and the start point of the other information block almost match. ,
That is, when only reproducing in one direction from one side to the other is performed, it is sufficient that the end point of one block of information and the start point of the other block of information almost coincide, and the information recording medium of the present invention It is fine as long as this condition is satisfied at the minimum, but there are cases where the image information is heard while reversing from one side to the other and then reversing from the other side to the other, that is, circulating the first information and the second information. Considering the large number of information, it is convenient to form the information so that not only the end point of one piece of information coincides with the starting point of the other piece of information, but also the end point of the other piece of information almost coincides with the starting point of one piece of information. In this way, the type EnB
This can be easily achieved when creating H (described in detail later).

Next, an example of a method for producing the videotape 11 shown in FIG. 1 will be explained together with an apparatus for producing it.

2) As shown in FIG. 8, the magnetic head 22 moves the track 2. The operator plays back the HAnE recorded in the HAnE, listens to this playback sound through headphones 31, checks the end point of each block of HAnE, and when the operator confirms, turns on the switch 33 for a certain period of time to turn off the noise generator. The generated noise is recorded on the cassette tape 1 via the magnetic head 23. As a result, as shown in FIG. 9, the 81st track 3-8 of the cassette tape 1 has the type HNn shown in FIG.
E is recorded. In this type 1 (NnE), noise is recorded as a mark representing the end position of each block of HAnE. At this time, the switch 32 selects the contact 32b on the playback side.

3) As shown in FIG. 11, the cassette tape 1 is reversed, and as shown in FIG.
The ENnH recorded on track 3-1 is played back, and the operator listens to this playback sound through headphones 31 and confirms the presence of noise (most strictly speaking, it is the point at which the noise ends). If the time for recording the noise is selected appropriately, it is not necessary to make them correspond so strictly), so that each block corresponding to the first audio information of the second audio information falls within the interval of each corresponding block of HAnE, That is, 1
(The operator reads the information of each block of nBE into the microphone 30 and records it on the cassette tape 1 via the magnetic head 21. In other words, each block of HnBE shown in FIG. It is read aloud at the same time as the noise indicating the position is confirmed.As a result, as shown in FIG. 11, the type HnBE shown in FIG. 3 is recorded on the cassette tape B, ) Rack 3-1. At this time,
Since the cassette tape 1 shown in FIG. 9 is reversed,
The B2 track 3-Q and B1 track 3-4 have E
This means that AnH and ENnH are recorded. Therefore, if the cassette tape 1 shown in FIG. 11 is reversed again, HAnE will be on track 2-2, HNnE will be on rack 3-1, and E will be on track 3 of B2.
