Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a recorded information recording medium disc, in particular, the reproduction of simultaneous stereoscopic television video signals, the reproduction of sequential stereoscopic television video signals, and 1. The present invention relates to a recorded information recording medium disc capable of carrying a television picture signal (a television picture signal used for reproducing a television picture (a flat picture television picture) that is not a stereoscopic picture).

(Prior art) In recent years, as high-density recording and reproducing methods using various recording media have been put into practical use, television video signals (hereinafter referred to as TV) have been recorded. Recorded information recording medium discs (video discs) in various formats are now available.

(Problems to be Solved by the Invention) Video discs using various recording and reproducing methods using various recording media that have been put into practical use up to now all record TV video signals that reproduce flat TV images. However, recently, the appearance of video discs recording stereoscopic TV video signals has become eagerly awaited. j By the way, as for the 3D TV system that displays 3D images,
Similar to making the viewer feel a three-dimensional image in a three-dimensional movie, the left and right eyes are made to see an image for the left eye and an image for the right eye, so that the viewer psychologically perceives a three-dimensional image. There are roughly two types of 3D TVs that follow the construction principle of
The method, ie.

- Simultaneous 3D TV systems and sequential 3D TV systems have been known for several decades, but it is well known that 3D TV broadcasting has not yet been put into practical use.

In order to easily obtain compatibility with the currently widely used TV system for reproducing flat images, the TV video signal for the left eye and the TV video signal for the right eye are individually separated. If the frequency bands allocated to broadcasting based on the current TV system are allocated for the broadcasting of TV programs, the actual number of channels allocated to TV broadcasting will be In addition, if a band compression means is applied to the TV video signal for the left eye and the TV video signal for the right eye, the rv system itself is not widely used. TV
This is difficult to implement because it is different from broadcasting, and if a TV video signal for the left eye and a TV video signal for the right eye are sent using the field sequential method, it is difficult to implement because it is different from broadcasting. This is because when reproduced on a machine, it is reproduced as a double image, which makes it unusable, and there are many other problems.

However, the problem of channel allocation that has become a problem in TV broadcasting is not relevant to video discs, and the TV system to be adopted can be determined with great freedom, so video discs can be used as a medium for 3D TV. It was considered meaningful to use it.

However, even if the video disc is for playing back 3D TV video signals, when it is played back by a video disc playback device that is already in widespread use, normal two-dimensional image playback and normal audio playback cannot be achieved. It is natural that it is desirable to be able to do this, and
A TV video signal for the left eye and a TV video signal for the right eye recorded on a video disc are converted into a 3D image by a 3D TV video signal playback device configured to play them simultaneously. It is used so that it can be reproduced,
Or a TV for the left eye recorded on a video disc.
It is also desirable that the present invention be used so that a stereoscopic image can be reproduced by a stereoscopic TV video signal reproducing device that is configured to sequentially reproduce a video signal and a TV video signal for the right eye. Therefore, there was a demand for a video disc that could satisfy each of the above-mentioned conditions.

(Means for Solving the Problems) The present invention provides for

The above points will be specifically explained below with reference to the drawings. Figures 3, 7, and 15.

Indicates the recording position where is recorded.

When the recorded information recording medium disk reproducing machine is brought into a state in which a video signal for planar image reproduction is reproduced from the recorded information recording medium disk of the present invention, the reproducing element performs recording as described later. Based on the first reproducing element displacement control signal read at the position of the square mark on the completed information recording medium disk, when the reproducing element first reaches around the 2-2 line position, the above-mentioned 2- A kick pulse is supplied to the actuator to displace the reproducing element inward by one recording trace interval within the area from the 2nd line position to the Y-Y line position, and the above-mentioned Z-Y line position and the above-mentioned Within the area between the Y-Y line position, the reproducing element is displaced to the inner circumference by one recording trace interval, and the reproducing element reads at the position of the circle mark on the recorded information recording medium disk. based on the second read element displacement control signal 2, both when the read element first thereafter reaches the vertical blanking period position and when it first thereafter reaches the Z-Z position; A kick pulse is supplied to the actuator to displace the reproducing element inward by one recording trace interval, and the reproducing element is displaced inward by one recording trace interval within the vertical blanking period. At the same time, within the area between the above-mentioned Z-Y line position and the above-mentioned Y-Y line position within the vertical blanking period a, the reproducing element is displaced inward by one recording trace interval. operation (Z-Y position so that the reproduction element displacement control signal recorded at the Y-Y position can be read by the reproduction element displaced by one recording trace interval)
(The reproducing device is configured such that the displacement region of the reproducing element is set between the line position and the YY line position.)

Therefore, the trajectory of the reproducing element when reproducing a TV video signal of a flat image from the recorded information recording medium disk of the present invention is shown in FIG. 3 (N=26 recorded information recording medium disk), FIG. 7, and FIG. (N=3 recorded information recording medium disk), FIG. 15 (N=4 recorded information recording medium disk), FIG. 19 and FIG. 23 (N=5 recorded information recording medium disk), It is as shown by the thick line in Fig. 27 (recorded information recording medium disc with N=6).

For example, when a field-sequential stereoscopic TV video signal is reproduced from the recorded information recording medium disc of the present invention, the recorded information read out from the recorded information recording medium disc as described later may be used. Based on the reference rotational phase signal fp3 of the information recording medium disc, kick pulses generated at predetermined timings in the reproducing machine for the recorded information recording medium disc are supplied to the actuators, so that the trajectories of the reproducing elements are changed to the fifth position. Figures (N=2), Figures 9 and 13 (N=3), Figures 17 (N=4), Figures 21 and 25 (N=5), Figure 29 (N=6) It will look like the bold line in each figure.

Furthermore, for example, when reproducing simultaneous stereoscopic TV video signals from the recorded information recording medium disc of the present invention, each of A 2g reproducing element that simultaneously reproduces the respective information signals of the adjacent left-eye video signal recording trace and the right-eye video signal recording trace of one round N field parallels the adjacent recording traces. It is done in such a way that it draws a trajectory that follows the target.

As mentioned above, it is possible to reproduce a video signal of a two-dimensional image from a recorded information recording medium disc, to reproduce a video signal for field-sequential stereoscopic image reproduction, or to reproduce a video signal of an extra-large stereoscopic image. The reproducing element used to reproduce the information signal is:

The reproduction operation is performed by drawing different trajectories depending on the reproduction mode of each member as described above, but regardless of the reproduction mode, the reproduction element that reproduces the information signal It goes without saying that not only the video signals corresponding to each reproduction mode can be obtained satisfactorily, but also the audio signals accompanying the reproduced video signals must be reproduced satisfactorily.

By the way, the reproducing element used to reproduce information and signals from the recorded information recording medium disc is capable of reproducing other recordings during the respective predetermined vertical blanking periods in any reproduction mode as described above. However, the position at which the reproducing element is displaced near the vertical blanking period usually varies depending on the reproducing machine. However, since there is no video signal during the blanking period, even if the position at which the reproduction millet is displaced near the vertical blanking period varies from reproduction machine to reproduction machine as described above, it is difficult to reproduce the image. Although this is not a serious problem, since the audio signal that accompanies the video signal is originally in the form of a continuous signal without interruption on the time axis, the playback element may be displaced between the recording traces. If the positions vary, there is a concern that the reproduced audio signal may be reproduced as discontinuous on the time axis.

Variations in the displacement position between the recording traces of the reproducing element at the Z-Z line position of the disc are due to the reasons described below. Information 1 When reproducing a video signal for flat image reproduction from a recording medium disk, and when reproducing a field sequential TV video signal from a recorded information recording medium disk in which odd-numbered field video signals are recorded in one round. In some cases, the audio signal becomes discontinuous, but in general, the position at which the reproducing element is displaced between recording tracks in a reproducing device usually varies depending on the reproducing device, so it is difficult to record recorded information. Some means is required to ensure that the audio signal reproduced from the medium disc is always in good condition, and in the recorded information recording medium disc of the present invention, the audio signal accompanying the video signal is By using a special mode of editing, the audio signal accompanying the video signal can be reproduced without any problems.

Next, a mode of editing an audio signal accompanying a video signal in the recorded information recording medium disc of the present invention will be explained.

First, let's start with the recorded information recording medium disc of the present invention.

Considering the case of simultaneous reproduction of stereoscopic TV video signals, as will be described later, in this reproduction mode, the two reproduction elements that follow the recording trace of the recorded information recording medium disk are as follows:
In order to reproduce video signals for the left and right eyes in the order of field numbers, the reproducing element is displaced to the adjacent recording trace at the Z-Z line position during reproduction. If an audio signal accompanying the video signal of each field is recorded in the recording trace on the completed information recording medium holiday 11D, the audio signal in this case is reproduced from one of the two reproduction elements. It is only necessary to use the audio signal that has been recorded, even if there are variations in the position at which the reproducing element is displaced in the Z-Z line position during reproduction.

This will not cause any discontinuity in the audio signal, so when the recorded information recording medium disc of the present invention is used to reproduce the video signal of a simultaneous stereoscopic television, the editing point of the audio signal will not be generated. There are no questions about what to do.

Next, considering the reproduction of an audio signal when a stereoscopic TV video signal for field sequential system is reproduced from a recorded information recording medium disc, the trajectory of the reproduction element in this case is shown in Fig. 5 (N22). 9 and 13 (N22 recorded information recording medium disk), 17 (N=4 recorded information recording medium g1), 21 and 25 (N: 5 recorded information recording medium disc), as shown by the thick line in FIG. 29 (N22 recorded information recording medium! 1).

In this way, when reproducing a 3D TV video signal for the field sequential system from a recorded information recording medium disc, the reproducing elements can follow the recording traces in the gID in the recording medium while displacing each in a predetermined pattern. This is required, but if the recorded information recording medium disc used for reproducing 3D TV video signals for the sequential system is one in which even-numbered fields of video signals are recorded during one rotation period. If the audio signal accompanying the video signal of each field is recorded for each field section, then Fig. 5 (N = 2 recorded information recording medium disc) and Fig. 17 (N=4 recorded information recording medium disc),
As is clear from the contents of the above-mentioned figures shown in Fig. 29 (N22 recorded information recording medium disc),
Even when reproducing a field-sequential stereoscopic TV video signal, the position at which the reproducing element is displaced is shifted either forward or backward relative to the Z-Z line position which is the original switching point.

Since the audio signal that is reproduced in this shifted state is the same as the audio signal that should originally be reproduced, a recorded information recording medium disk in which an even field of video signals is recorded in one rotation is 3D T of field sequential method from
When reproducing a V video signal, no problem occurs in the connection of audio signals.

However, it seems that the video signals of an odd number of field periods are recorded in one round period, and the audio signal accompanying the video signal of each field is recorded for each field period. When reproducing a field-sequential stereoscopic TV video signal from a recorded information recording medium disk, the following steps are required: Figures 9 and 13 (N22 recorded information recording medium date II), Figures 21 and 25 (N=
As is clear from the contents of the recorded information (recorded information 1 information recording medium disc) in Section 5, it is clear from the predetermined switching point, that is, which position the reproducing element is displaced relative to the Z-Z line position. It can be seen that even if it shifts slightly to the side, discontinuity occurs in the sound.

Next, considering the reproduction of an audio signal in the case of reproducing a video signal for planar image reproduction from a recorded information recording medium disc, the trajectory of the reproducing element in this case is shown in Fig. 3 (N = 2). Recorded information recording medium disk), Figures 7 and 11 (N22 recorded information recording medium disk)
, FIG. 15 (N=4 recorded information recording medium disk), 1st
Figures 9 and 23 (N=5 recorded information recording medium disc)
, as shown by the thick line in FIG. 27 (N22 recorded information recording medium disc).

If each of the recorded information recording medium discs has an audio signal accompanying the video signal of each field recorded for each field section, the recorded information recording medium disc is When a video signal for planar image reproduction is reproduced from the above, as is clear from the contents of the above-mentioned figures, the position at which the reproduction element is displaced is at a predetermined switching point, that is, Z-Z. It can be seen that if there is even a slight deviation toward the front with respect to the line position, discontinuity occurs in the sound.

When a video signal for reproducing a flat image is generated from a recorded information recording medium disc as described above, the position at which the reproducing element is displaced is at a predetermined switching point, that is, Z-
The sound becomes discontinuous when it deviates from the Z-line position, and the field-sequential 3-dimensional structure of a recorded information recording medium disk in which video signals of odd-numbered field periods are recorded in one rotation. When generating TV signals,
We will specifically explain with reference to the drawings that the sound becomes discontinuous when the displacement position of the reproduction element deviates from a predetermined switching point, that is, the Z-Z line position. First, however, an additional comment should be made regarding the method of representing audio signals employed in this specification and the accompanying drawings.

That is, the audio signal display adopted in this specification and the accompanying drawings is such that the video signal recorded in the field with the field number Ll is displayed as Llg, and the video signal recorded in the field with the field number as R2.
The video signal recorded in the field with field number is L2s, and the video signal recorded in the field with field number R3 is L3.
g, the video signal recorded in the field with field number R4 is L4g, the video signal recorded in the field with field number R1 is Rlg, the video signal recorded in the field with field number R2 is R2s, the field number is The video signal recorded in the field of R3 is
, etc. However, for audio signals accompanying 3D TV video signals, the left-eye video signal of the field with the same field number is used. Since the audio signal accompanying the left eye video signal of the field having the field number with the same number is originally the same, the above-mentioned L is, L
2s, L 3s.

... Rls, R2g, etc., to display audio signals with the same subscripts, but without distinguishing between L and H, 1s, 2s, 3s, etc. It is also said that the audio signal is displayed by adopting a method of expression.

Now, as mentioned above, in order for the playback device to play back video signals according to various playback modes, the playback elements must each draw a predetermined trajectory and follow the recording trace according to each playback mode. At this time, the reproducing element is required to be displaced at a predetermined position on the recorded information recording medium disk by a distance corresponding to a predetermined number of recording trace intervals.

However, when the reproducing element is required to be displaced as described above, the actual position of the reproducing element will naturally vary depending on the reproducing machine used to reproduce the recorded information recording medium disc. It happens.

That is, the displacement of the reproducing element described above is determined by a kick pulse generated within the reproducing machine being supplied to the actuator based on the reproducing element displacement control signal Kl (R2) read by the reproducing element from the recorded information recording medium disc. , the reproducing element reads the recorded information from the recording medium disc. standard. Phase shift signal f23. -1 This is caused by the kick pulse created in the regenerator being supplied to the actuator, but the timing of the displacement of the reproducing element caused by the actuator driven by the kick pulse created in the regenerator depends on the individual Since there is some variation between playback devices, even if the planned position of the displacement of the playback element is said to be the z-Z line position, the actual position of the playback element will be the z-Z line position.
It will vary around the Z-line position.

(a) to (c) in FIG. 31 show f in the recorded information recording medium.
This is a diagram for explaining that when a video signal for planar image reproduction is reproduced from an iD, the connection state of audio signals may become unsatisfactory when the displacement position of a reproduction element varies. , First, as shown in (,) in FIG. 31, the audio signals R4s, L5s, accompanying the video signals of the respective fields R11°R5, R8, R5,
Considering the case where L8s and R5s are recorded in correct correspondence with the field section in which the video signal of each field is recorded, in this case, the position where the reproducing element is displaced is the field switching position (in Figure 31). If there is even a slight deviation toward the section (section with field number R4) up to the point (Z-2 line), the state of the connection of the audio signals will deteriorate.

In other words, the audio signal R4s accompanying the video signal.

The switching position of L 5s, L 8s, and R5s is 31st.
As shown in (a) in the figure, when the Z-Z line position coincides with the field switching position, if the position where the reproducing element is displaced becomes the field R4 side, the reproduced audio signal will be like R4snL8g-+R5g. This is because unnecessary audio signal L8g is mixed in at the time of switching.

However, the audio signals R4s, L5s accompanying the video signal,
Even if the L8s and R5s switching positions match the field switching positions as shown in FIG. 31(a), the position where the reproducing element is displaced is on the field R5 side as shown in FIG. 31(c). In this case, the audio signal to be played is R4
5-+ L5s (L5+= R5g==5s) → R5s
Therefore, unnecessary audio signals are not generated during switching.

So, in order to prevent the above problem from occurring,
As shown in FIG. 31(b), the audio signal L5s accompanying the video signal of field R5 may be recorded at least at the end of field L8 before field R5. .

Therefore, in the recorded information recording medium disc of the present invention, if it is only necessary to solve the problem of the connection of audio signals when playing back a video signal for playing back a two-dimensional image, editing of the audio signal is necessary. Point CS may be provided on the near side of a specific radial position z-z line position on the recorded information recording medium disc. Then, by applying the above-mentioned means, for a recorded information recording medium disc in which an even field video signal is recorded in one round period, a simultaneous stereoscopic TV video signal can be reproduced. Even when using field sequential 3D TV
Whether you are reproducing a video signal or a video signal for flat image reproduction, it is possible to prevent problems in the connection of audio signals. In the case where an odd field video signal is recorded, the reproducing element must be displaced by the interval of two recording traces required when reproducing a field sequential video signal. This causes an inconvenience in the connection of the audio signals, and this point will be explained with reference to (a) to (d) of FIG. 32 as follows.

FIG. 32 is an illustration of the locus of the reproducing element shown in FIG. 9 when reproducing a field sequential video signal from a recorded information recording medium disk in which three fields of video signals are recorded in one revolution. FIG.

When reproducing a field sequential video signal from a recorded information recording medium disk in which three fields of video signals are recorded in one revolution, the reproducing element is shown by the thick solid line in FIG. 9, for example. However, the reproduction element is displaced at the 2-2 line position at intervals of two recording traces.

When reproducing a video signal of the J method field sequentially from a recorded information recording medium disk in which three fields of video signals are recorded in one revolution, the reproducing element is displaced at the planned displacement location at the Z-2 position as shown in Fig. 32. As shown in (,), if the editing point C3 of the audio signal is displaced by exactly two recording trace intervals at the Z-Z line position, then in the example shown, The reproducing element reproduces the video signal of field 3→field R4, and the audio signal accompanying the video signal of each field reproduced accordingly becomes continuous like 3s→4s.

However, if the location where the reproducing element is displaced between the recording traces deviates from the Z-Z line position where the editing point C5 of the audio signal is located, as shown in FIGS. 32(b) and (C), ,
The reproducing element detects the audio signal 6s, which originally does not require reproduction, when switching from the audio signal 3s to 4s, such as the audio signal 3s → 6s → 4s accompanying the video signal of field 3 → field L6 → R4. ((b) in Figure 32), or the audio signal 3s accompanying the video signal of field 3 → field R1 → R4 → 1
The audio signal 68, which is not originally required to be reproduced, such as from s to 4s, appears in the middle of the switching from audio signal 3s to 48 ((e) in Figure 32), and the connection of audio signals is interrupted. make the condition of the item poor.

FIG. 32(d) shows a case where a video signal of a field sequential system is reproduced from a recorded information recording medium disc in which three fields of video signals are recorded in one revolution.

As shown in FIG. 32 (b), there is a planned displacement area of the reproduction element on the near side of the Z-Z line position to prevent the connection of audio signals from becoming discontinuous even if there is variation in the displacement of the reproduction element. By intentionally setting zC, 2
Even if the position of the displacement of the reproducing element which is to be displaced by the recording trace interval varies within the range of variation among the reproducing machines, the displacement of the reproducing bare hand is within the planned displacement area ZC of the reproducing element.
FIG. 3 is a diagram illustrating a solution in which the connection between the reproduced audio signals is maintained in a good condition by making the reproduction within the same area.

That is, in (d) of FIG. 32, C3I is the first line of the audio signal placed at the 2-2 line position corresponding to the end point of the expected displacement area ZC of the reproduction element where the displacement of the reproduction element is set. 1 edit point SCI, and C52
is the second editing point SC2 of the audio signal provided corresponding to the starting point of the expected displacement area zC of the reproducing element, and the audio signal to be recorded in the expected displacement area zc of the reproducing element starts when the reproducing element starts displacement. In the example shown in FIG. In the expected displacement region zc of the element, an audio signal 3s accompanying the video signal with field number L3 is recorded as an audio signal that meets the above-mentioned conditions.

As in the example shown in FIG. 32(d), by setting a planned displacement area ZC of the reproducing element in which an audio signal meeting the above-mentioned conditions is recorded.

The problem of connection of audio signals, which was a problem when reproducing field sequential video signals from a recorded information recording medium disk in which three fields of video signals are recorded in one revolution, can be solved satisfactorily.

That is, if the reproducing element is displaced within the expected displacement region zC of the reproducing element as described above, the audio signal reproduced at that time will be 3s → in the example shown in FIG. 32(d). 4s, and it is clear that the problem of audio signal discontinuity does not occur. Note that the starting point of the above-mentioned displacement planned region zC of the reproducing element may be provided anywhere within one field immediately before the Z-Z line position.

In the recorded information recording medium disc of the present invention, the connection of audio signals is improved in playback modes and during playback operations in which connection of audio signals becomes a problem when the playback element is displaced between recording traces. The conditions that should be provided for the position of the editing point of the audio signal so that the audio signal can be edited have already been made clear from the explanation with reference to FIGS. 31 and 32. The question is whether the position of the editing point of the audio signal is appropriate even when the information signal is being played back from the recorded information recording medium disc in other operating states, so this point should be considered. The result is as follows.

Okay, from the start. Recorded information recording medium □. (1) When reproducing a video signal for reproducing a two-dimensional image, if the reproducing element fails to read the first reproducing element displacement control signal and mistracks, the displacement of the first reproducing element that has failed to be read is Based on the reading result of the second reproducing element displacement control signal that appears after the control signal, an operating state is determined in which the reproducing element returns to the original recording trace with only one field of mistracking (Fig. 4). , FIG. 8, FIG. 12, FIG. 16.

In each of FIGS. 20, 24, and 28, when a video signal for planar image reproduction is being reproduced from a recorded information recording medium disk, the reproduction element performs the first reproduction element displacement control. When mistracking occurs due to failure to read a signal, based on the reading result of the second reproduction element displacement control signal that appears next to the first reproduction element displacement ** signal which was failed to be read, mistracking for ■ field is performed. N=
2, N = 3, N = 4, N = 5, N = 6 recorded information recording medium disks are illustrated and explained, and in each figure, the trajectory indicated by a thick dotted line is If we consider the case where the audio signal is played back from the record trace that would have been followed if mistracking had not been performed, / is the same as the audio signal that should be obtained from the original recording trace, and the audio signal editing points explained in Figures 31 and 32 are included in the recording trace that is traced during mistracking. Since C5, C31, and C52 do not exist, during playback operation when the playback element fails to read the first playback element displacement control signal and mistracks while playing back the video signal for planar image playback. about,
The position of the editing point of the audio signal determined as described above is irrelevant.

In addition, from the recorded information recording medium disk to the simultaneous method three-dimensional T
When a V video signal is played back, it is only necessary to use the audio signal from one of the two recording traces recorded in parallel, so in this case as well, as mentioned above, The position of the edit point of the defined audio signal is irrelevant.

The locus of the reproducing element during the operation is shown superimposed on a single drawing using thick solid lines.

22, 26, and 30, there are recording traces that are not traced by the reproducing element in any of the aforementioned reproduction modes.
Furthermore, it can be seen that the editing points of the audio signal explained with reference to FIG. 31 and FIG. The position of the audio signal editing point CS and the position of the audio signal editing point C52 on the disc are 2-2 on the disc.
As long as it is within one field period immediately before the line position, it can be known that it can be set at any part of that period.

The position of the editing point of the audio signal in the recorded information recording medium disk of the present invention should be set by taking into consideration the various conditions related to the editing point of the audio signal, and is as shown in FIGS. FIG. 30 shows examples of editing points C3, C51, and C52 of the audio signal in each case.

The square mark shown at the intersection of Y-ym and the recording trace near the specific radial position Z-7 line indicating the reference phase of the rotational phase within the blanking period NJa of D is z- 1 is recorded in the first reproducing element displacement control signal for displacing the reproducing element to the recording trace on the inner circumference of the recorded information recording medium disk by l recording trace interval (1 track pitch) near the position of the Z line. It shows the recording position where the
The circle mark shown at the intersection of the Y line and the recording trace is the position of the vertical blanking period that appears next to the vertical blanking period a where the Z-Z line is, and the reproducing element is moved to one recording trace. Displace the recording trace on the inner periphery of the recorded information recording medium disk by an interval, and then displace the reproducing element to the recording trace on the inner periphery by one recording trace interval near the position of the z-7 line that appears next. This shows the recording position where 2 is recorded in the second reproduction element f-displacement control signal. A reproducing machine for a recorded information recording medium disc receives a video signal for reproducing an east image from the recorded information recording S medium disc of the present invention.
As will be described later, in the case where the reproducing element reads 1 in the first reproducing element displacement control signal at the position of the square mark on the recorded information recording medium disc I), the reproducing device , based on the first reading element displacement control signal read above, when the reading element first reaches the vicinity of the z-Z line position, the reproduction element is moved around the 2-2 line as described above. By supplying the actuator with a kick pulse that causes the actuator to be displaced toward the inner circumference by
7. When the line is close to 100 km, perform an operation to displace the reproducing element inward by one recording trace interval, and move the reproducing element to the second position at the position of the circle on the recorded information recording medium disc. When reading 2 in the reproduction element displacement control signal, the reproduction machine determines the time when the reproduction element first reaches the position of the vertical blanking period after that, based on the read second reproduction element displacement control signal. , and thereafter, at the time when the Z-Z line position approaches the first interval, a kick pulse is supplied to the actuator to displace the reproduced element -f inward by one recording trace interval. , +Ij The raw cable f is displaced inward by one recording trace interval within the vertical blanking period a, and also near the Z-7 line position described above within the vertical blanking period a. An operation is performed to displace the reproducing element inward by one recording trace interval. Then, when the reproducing element reads 1 in the first reproducing element displacement control signal and 2 in the second reproducing element displacement control signal when the reproducing element is in the reproducing mode of a video signal for reproducing a planar image, the above-mentioned process is performed in the reproducing device. Among the displacement operations of the reproducing element, the operation of displacing the reproducing element by one recording trace interval near the 2-2 line position is based on the reproduction incomplete-displacement control signal recorded at the Y-Y line position. The region to be displaced (displacement region of the reproducing element) of the reproducing element 1 is set by the configuration of the reproducing device so that the reproducing element /- after being displaced by one recording trace interval is always read. It is required that the In the video signal playback mode for planar image playback described above,
The displacement area of the reproducing element that is displaced by one recording trace interval near the 2-Z line position on the recorded information recording medium disc has its end point, that is, the position where the reproducing element ends being displaced is Y-Y.
It is clear from the above that it must be closer to the Z-Z line position than the line position, but the starting point of the displacement area of the reproduction element described above also takes into consideration the position of the editing point of the audio signal, which will be described later. Therefore, it is necessary to set it near the z-7 line position. By the way, as will be clear from what will be described later, the position of the editing point of the audio signal mentioned above is determined in two cases: when the number of fields of the video signal recorded in one revolution of the recorded information recording medium disk is an odd number; Since the starting point of the displacement area of the reproducing element described above is different depending on the case where the number of fields is an even number and the number of fields of the video signal recorded in one revolution of the recorded information recording medium disk is an odd number and when the number of fields is an even number, Although the playback method may differ depending on the case, it can be commonly used in both cases where the number of fields of the video signal recorded in one revolution of the recorded information recording medium disk is an odd number and an even number. As the displacement area of the element, the displacement area of the reproduction element described above can be defined between the z-Z line position and the Y-Y line position on the recorded information recording medium disc, and in this way, the reproduction element The locus of the reproducing element when a flat image TV video signal is reproduced from the recorded information recording medium disc in the case where the displacement area is determined is shown in Fig. 3 (recorded information recording medium disc with N = 2). , Fig. 7 and Fig. 11 (recorded information recording medium disc with N = 3), Fig. 15 (recorded information recording medium disc with N = 4), Fig. 19 and Fig. 23 (recorded information recording medium disc with N = 5). For each of the cases shown in FIG. 27 (pre-recorded information recording medium disk) and FIG. 27 (pre-recorded information recording medium disk with N=6), the results are as shown by the thick lines in the respective figures.
