The method is characterized by comprising a step of dubbing the second information recording medium so that the starting points of the second blocks corresponding to the blocks coincide with each other to form a third information recording medium.

Furthermore, the information recording medium producing apparatus according to the present invention is capable of adjusting the running direction of the magnetic recording medium in correspondence to each of the four parallel first to fourth tracks, which are pairs of two adjacent tracks of the information recording medium. a recording signal processing means connected to the first and third or second and fourth heads; and a second or first head. A recording signal processing means and a reproduction signal processing means connected to the fourth or third head via a changeover switch, a reproduction signal processing means connected to the fourth or third head, and an information recording medium via the third or fourth head. a noise generating means connected to the third or fourth head to record noise; The present invention is characterized in that one head is used for recording and reproducing information, and the fourth or third head is used for reproducing information.

(Function) According to the present invention having the above configuration, the second information corresponding to a block that is a part of the first information is recorded on the other track of the information recording medium on which the first information is recorded. It is possible to easily record the first information in the direction opposite to the temporal flow direction of the first information so as to correspond to the corresponding block. By reproducing the first and second information, and reversing to another track when the block consisting of them is completed, the second and first information corresponding to the first and second information are reproduced.

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

FIG. 1 is an explanatory diagram conceptually showing a recording surface of a cassette tape, which is an information recording medium according to a first embodiment of the present invention. In the figure, 1 is a cassette tape according to this embodiment;
2 is the A track, and 3 is the B track. A track 2
Music, which is continuous information, is recorded.

In this embodiment, this music is the first information. B
In track 3, each block consists of an arbitrary period that is a part of the music! A-171...I-I-A
-4# Explanations corresponding to IA-4 are recorded. In this embodiment, this explanation is the second information. At this time, each block in which explanations are recorded on B track 3 ■6-1"6-2"ll-3# 111-
4”!1-Is are the blocks I to which these correspond, respectively.
A-1" The temporal positional relationship is almost the same as IA-8, and the direction opposite to the direction of the temporal flow of music is the normal flow direction of information during playback. Therefore,
The starting point of each block 'A-1 to IA-1i and each block■
, -1 to ■8-5 end points are also each block 'A-'
i to the end point of IA-15 and each block 1. -8～■e-s
coincides with the starting point.

The starting point of block IA-, ~'A4 here is the position where the middle of the music corresponding to each explanation begins, and the same block!
, ~■ The end point of A-1i is the position where the middle of the music corresponding to each explanation ends.

Furthermore, blocks l8-1 to 1. The starting point and ending point of -5 are the starting and ending positions of each explanation. Furthermore, the term "the end point and the start point and the start point and the end point match" does not mean a match in a strict sense, but by reversing the first information block I-T and the second information block Oy corresponding thereto. This means that a relationship is maintained such that both i to ■ can be matched and reproduced (the same applies hereinafter).

In the information recording medium produced by the production method described below, there may be cases where the end point and the starting point and the starting point and the ending point are not separated by + or 1 - in a strict sense, but this may pose a practical hindrance in view of the operation and effect of the present invention. A “deviation” of no degree is considered a “match”.

In this way, AI rack 2 has blocks 1A-1 to ■
The music, which is the first information, is recorded continuously without being interrupted by A-5, but the commentary, which is the second information, is recorded in the adjacent blocks I-,-I on the B track 3.
are recorded discontinuously with spaces in between.

The suffix added to 1 in Figure 1 corresponds to blocks with matching numbers, and the suffix added to the right side of the figure 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 explanations recorded in the proboscis blocks Ia-t to Ia-s and these blocks l8-1 to Ia-s can be read by performing the following operations. 1. It is possible to alternately listen to the middle of the music recorded in blocks IA-1 to IA-5 corresponding to blocks IA-5 and IA-5, respectively.

For example, block 1. After asking for the explanation of -2, write the music of block r corresponding to that ' part v! If you want to go to 1, B
Blocked by playing track 3! , -2, and when the commentary is finished, operate the reverse key to switch to the reproduction of A track 2. This results in block I
The music is played from the starting point of A-2, and the music corresponding to the explanation of block ■&-2 can be heard.

At this time, if you operate the reverse key again at the end of block IA-12, you can listen to the explanation of block-2 again.

Another block! 6-1” After listening to the explanations of 6-3 to I a-5, draw the blocks corresponding to each part ■A-111A-
If you want to listen to music from 3 to IA-G, you can perform 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.

Next, a second embodiment of the present invention, which is a method for creating the recording surface of the cassette tape 1 shown in FIG. 1, will be explained in detail.

1) As shown in FIG. 2(a), a tape l on which music, which is the first information, is recorded is played back by a tape recorder 11, and while listening to this, the operator can make a sound through the microphone 12 at any position. The tape recorder 13 records the explanation, which is the second information, on the virgin tape, and at the start of the playback of the tape 6 and the end of the explanation, the control device 14 is operated to record the tape recorder 15 for a certain period of time (for example, 1 A short period of about seconds) is set to playback mode, and the noise tape N0 on which noise is continuously recorded is played back as shown in FIG. . At this time, the tape recorder 11°1
6, this state continues once playback and recording start. Then, reproduction and recording by the tape recorders 11 and 16 are simultaneously started.

On the other hand, the tape recorder 13 has a fiVOR function, in which when a sound or voice of a certain intensity or higher is input during recording, the tape automatically rotates and recording begins, and when the recording is interrupted, it automatically stops.

As a result, as shown in FIG. 3(b), it indicates the end point of blocks IA-1 to IA-1 corresponding to the portion marked with Ha on the tape I on which music, which is the first information, is recorded. Noise (shown as a block with a black dot in the figure; the same applies below)
As shown in FIG. 3 (cl. tape formed through the space part of
■,, are created.

Among these, noise tape N is blocks IA-1 to 'A-.
4 is recorded as temporal position information, but the present invention is not limited to this. For example, the point at which the explanation ends corresponds to the time position on tape IA,
Of course, it may be stored in a readable storage means such as a PU.

Furthermore, the method for creating the tape Ie11 is not limited to the above method. That is, the music that is the first information may be broadcast via a sound source such as a radio (in this case, while listening to the music broadcast, the tape I□
All you have to do is create .

2) As shown in Figure 2 [bl], the tape recorder 13
rewind and playback mode, and tape recorder 17 in recording mode, each block 18-8~ of the tape 'at
Dubbing is performed so that I and -6 are arranged in reverse order.

To comment further, drive the tape recorder 13 in rewind playback mode, listen to the playback sound at this time, and record the tape I.
The space section name tape I61 is rewound from the rear of the last block of 6□ (l6-5 in the figure) to the front of the same block ■a-s. After that, the tape recorder 13 is set to playback mode.
Turn the tape recorder 17 into recording mode and drive both simultaneously.While listening to the playback sound, tape Ill is dubbed onto a virgin tape, and when the end of block IB5 is passed, drive the tape recorder 13.17. Make it stop.

By the same operation as above, the space part name tape I61 from the rear of block 8-5 to the front of block IB-4 is rewound, and then by the same operation as above, block 1.
Dubbing -4.

Similar operations are repeated for blocks lll-3 to l6-8.

As a result, the tape I8 created by the tape recorder 17
2, as shown in FIG. 3(e), blocks 1-4 to ■
a-s are reversely arranged, and the adjacent block Ie
It has an arbitrary space part in l-1 to --, rR.

3) As shown in Figure 2 (el), the tape recorder 16
While running the noise tape N4 in the opposite direction and listening to the reproduced sound, the tape recorder 17 plays back the tape I8°.
This tape 112 is dubbed onto a virgin tape using the tape recorder 1B.

To further comment, when the tape recorder 16 is set to the playback mode and the noise tape N1 is run in the reverse direction, at the same time the tape recorder 18 is set to the record mode and the virgin tape is run while the playback sound of the noise tape N is interrupted and the block' When the noise corresponding to the end point of A-5 is confirmed, the tape recorder 17 records the tape! , 2 starts playing.

As a result, the block ■ will be dubbed on the virgin tape. At this time, while monitoring the playback sound of the tape recorder 17, the drive of the tape recorder 17 is interrupted when it is confirmed that the block (2) has ended. Next, block! When the noise corresponding to the end point of A-4 is confirmed, the tape recorder 17 starts playing tape I, and +12 block 1. - Stop dubbing when the end of step 4 is confirmed.

Repeat the same operation below and block ■, -3 to ■8-
Dubbing 1.

At this time, the noise tape N and the virgin tape continue to run after once running.

Note that existing cassette tape recorders cannot play the tape at standard speed while running the tape in the reverse direction, so it is necessary to modify the cassette tape recorder so that it can play the tape in the reverse direction, or to use an open-reel tape recorder. A tape recorder must be used. Furthermore, while providing information that traces the end positions of blocks "A-1" to "■A-5" on tape (6) in reverse, by other methods, for example,
The timing of reproduction of the tape I by the tape recorder 17 may be controlled by reading out the end point position information stored in the PU in reverse temporal order.

As a result, the tape 18 created by the tape recorder 18
3, as shown in FIG.
are arranged in reverse order, and adjacent blocks l6-8~
(2) The interval between 8-5 is equal to the interval between corresponding adjacent blocks I to (2) on tape IA.

Strictly speaking, this interval may vary depending on the width of the noise on the noise tape N, but tape! If the width of the space portion in is made approximately equal to the width of the noise, and reproduction of the tape 17 is interrupted at the point where the noise breaks in this step, it can be regarded as equidistant in practical terms. In addition, to avoid such operations (but to reduce the width of the noise, and to aid understanding in the figure, extremely large convergence is used for blocks A-1 to I and 1 to ■). ) and the width of the space in the tape 18□ is made smaller (
4) As shown in Figure 2(d), if the tape recorder 18
While playing back tape I, this played sound is dubbed onto the other track (B track) of tape [A] using Cheap Record 11.

To comment further, tape IA is started with the reference point behind block I on tape IA, for example, the point corresponding to the end point of the noise corresponding to the end point of block A-5.
is inverted and *ta is recorded on the tape recorder 11. That is, the reference point of tape 1 is made to coincide with the reference point of tape '&3. Then tape on tape recorder 18! 83 and recording on the tape recorder 11 to another track of the tape 1 is started at the same time.

As a result, as shown in FIG. 3 (gl), a tape IAe similar to that in FIG. 1 is created.

In the above embodiment, the information recording medium was explained as a cassette tape, but any information recording medium that realizes the first embodiment can be used to record continuous information and other information corresponding to a portion thereof using the same method. It can be created to correspond by reversing the flow of information.

A third embodiment of the present invention is a tape "93" shown in FIG. 3 (fl).

Once this tape I is created, tape I can be easily created by combining it with the first information to be broadcast.

To comment further, in step 1) of the method of the embodiment, tape IBL and noise tape N1 are created based on the first information broadcast, and tape I is created by going through steps 2) and 3). If so, record the first rebroadcast information on tape IA, and dub tape ■83 onto other tracks of tape ■ in the same manner as in step 4) to create tape IA&. can. Namely, the tape in this case! . 3 can be an independent product as a tape for making tape ■All.

Therefore, the method for creating the tape 1113, namely 1) to 3)
A manufacturing method including the steps described above can also be a method of another example, which is a fourth example of the present invention.

Here, the types of first information, second information, and noise information necessary to create an information recording medium created by an embodiment apparatus described later 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

yuki, awe, tsuki, and kaze, and if these are illustrated according to the above definition, they will be as shown in FIG. 4.

On the other hand, the noise information is for each block IA-L~ of the first information.
This information indicates the position of the end point of IA-s.
And when expressed in correspondence with the second information, H, NnE,
HnNE, EnNH, ENnH. However, since noise information is essentially meaningless information, H-
There is no need to distinguish between the case of 4E and the case of E←H,
Therefore, HNnE-HnNH, EnNE=ENnH, and these are illustrated as shown in FIG.

Next, using the mold defined as described above, a method according to the fifth embodiment of the present invention and a sixth method for realizing the method according to the present invention will be described.
