Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus that records information signals in each of a plurality of areas on a recording medium.

[Conventional technology]

Hereinafter, in this specification, an example will be given of a multi-channel digital audio tape recorder that compresses the audio signal in the time axis and records digitally modulated data independently using a rotary head on six channels extending in the longitudinal direction of a magnetic tape. I will explain it to you.

FIG. 7 is a diagram showing part of a tape running system of a conventional digital audio tape recorder of this type. In FIG. 7, 1 is a magnetic tape, and 2 is a rotating cylinder that holds a rotating head 3.4. As a result, the heads 3 and 4 trace the tape 1 diagonally and record audio signals. Then, each time the heads 3 and 4 rotate by 36 degrees, a time-axis compressed audio signal is recorded in each of the six regions formed in the longitudinal direction of the tape 1, so that a total of six channels of audio signals can be recorded. You can get a dedicated tape recorder.

In FIG. 8, CHI to CH6 are respectively head 3 or head 4 in FIG. 7 from A to B, B to C, and C.
This is the area (channel) in which audio signals are recorded during the period when tracing from D to E, E to F, and F to G. Audio signals can be recorded separately in each area, and so-called azimuth overwriting is performed in each area, but the tracks in each area CHI to CH6 do not need to be on the same straight line. In addition, a pilot signal for tracking control is recorded in each area, and a predetermined rotation (fl-+r2→f, →f4) is performed for each area.
), and there is no correlation between the areas.

Also, the area indicated by CHI to CH3 is tape 1 in FIG.
Assuming that recording and reproduction are being performed when the is traveling at a predetermined speed in the direction shown by arrow 7, and recording and reproduction is being performed in the area shown by CH2-CH2 when it is also traveling in the direction shown by arrow 9, then As shown in FIG. 8, the inclination of each track in the area indicated by CHI to CH3 and the inclination of each trunk in the area indicated by CH2 to CH2 are slightly different. However, regarding the difference in relative speed at this time, compared to the difference due to the rotation of heads 3 and 4,
It is assumed that the damage caused by the running of the tape 1 is extremely small and therefore does not pose a problem.

FIG. 9 is a time chart of recording and reproduction of the above-mentioned tape recorder. In the figure, (a) is a phase detection pulse (hereinafter referred to as PC) generated in synchronization with the rotation of cylinder 2, which is 1/6
“High level (H)” and “low level (L)” every 0 seconds
It is a 30Hz rectangular wave that repeats ". Also, (b) is a PG of opposite polarity to PG (a). Here, PG (a) is a HXPG while the head 3 rotates from B to G in Fig. 7. (
b) is assumed to be H while the head 4 similarly rotates from B to G.

Figure 9(C) shows the data reading pulse obtained from PC(a), which is used to sample the audio signal every other field in a period corresponding to one field (1/60 seconds) of the video signal. It is something. FIG. 9(d) shows R
Adding redundant code for error correction using AM etc.
The signal processing period for changing the arrangement is indicated by H. In FIG. 9(e), the data recording period is indicated by H, and the timing at which the recording data obtained by the above-described signal processing is recorded on the tape 1 is indicated.

For example, if we follow the signal flow in time using Figure 9,
Data sampled during the period t1 to t3 (while the head 3 is moving from B to G) is sampled from t3 to t5 (while the head 3 is moving from G to G).
Signal processing is performed at A), and from t5 to t6 (head 3 is
B) is recorded during the period.

That is, the head 3 records in the CHI area in FIG. On the other hand, data sampled while PG(b) is H is signal-processed at the same timing and recorded in the CHI area by the head 4.

FIG. 9(f) shows a PG obtained by shifting the phase of PG(a) by a predetermined phase (here, 36° corresponding to one region).

Hereinafter, a case will be described in which an audio signal is recorded using PG(f) and a PG (not shown) having the opposite characteristics. The data sampled from t2 to t4 in Fig. 9 is from t4 to t4.
During t6, the signal is processed according to the signal shown in FIG. 9(g), and between t6 and t7, it is recorded according to the signal shown in FIG. 9(h).

That is, data is recorded by the head 3 in the area indicated by CH2 in FIG. 8 during the period when the head 3 traces B-C. Similarly, data sampled during the period t4 to t7 is recorded by the head 4 in the area indicated by CH2.

Next, the operation of reproducing the signal recorded in the area indicated by CH2 will be explained.

Reading of data from tape 1 by head 3 is shown in FIG.
t6 to t7 (same for tl to t2) according to the signal shown in h)
t7 to t8 (
From t2 to t3), signal processing opposite to that during recording is performed. That is, error correction and the like are performed during this period, and a reproduced audio signal is output from t8 to t9 (t3 to t6) in accordance with the signal shown in FIG. 9(j). Of course, the reproduction operation by the head 4 is performed with a phase difference of 180 degrees from the above-mentioned operation, and thus a continuous reproduction audio signal is obtained.

Also, regarding other areas CH3 to CH6, PG(a)
Needless to say, the above-mentioned recording/reproducing operation can be performed based on the phase of n×36°, and this does not depend on the running direction of the tape. An example of a data format that has been conventionally used will be explained below. FIG. 2 is a diagram showing an example of the data format recorded in one track of each area in FIG. 8, that is, the format of data containing PCM audio data corresponding to a two-channel audio signal of 1/60 seconds. .

In the data matrix shown in the second λ, the column indicated by 5ync is a synchronization data column, the column indicated by address is an address data column, the columns indicated by P and Q are redundant data columns for error correction, respectively, and the column indicated by CRCC is a well-known 0 CRCC check hood. The data columns DI and D2 include columns for the number of husband and wife membranes, each with 2
This is a data string containing channel audio signal information. On the other hand, b(0) to b(3x-1) indicate each row of this data matrix, and each row is recorded as one data block sequentially from the left side to the right side in the figure. For example, after b (Q) 5 sync column data, the address column data of b (0), and then b (0)
The data is sequentially recorded as P column data. Also b(
After the last column data of 2), 5sync of b(J3+1)
Column data is recorded, and when the final column data of b(3x-1) is recorded, data recording for one track is completed.

Here, in the first column included in Dl, b(0),
b(1), b(x), b(x+1), b(2x), b(
2x+1) six data (IDO to ID5) are data (IDO to ID5) corresponding to additional information other than audio signal information.
(hereinafter referred to as ID data).

Incidentally, the multi-channel digital audio tape recorder as described above can be provided with a function of recording or reproducing by changing channels.

This function is extremely useful as it allows continuous recording for long periods of time.

On the other hand, in order to realize this coffin function, it is necessary to set the recording end point of the track before the change, the channel number after the change, the recording direction of the signal in that channel, the recording start point, and the tape speed at the time of recording. The data required for the change must be recorded in the channel before the change.

Also, as is well known, this heel tape recorder can also be used as a VTR, but in order to distinguish whether the signal recorded on the recording tape is a video signal or an audio signal, it uses a well-known four-frequency system automatic tracking control. A pilot signal having a frequency (f5) different from the four types of pilot signals used in the digital audio signal was frequency-multiplexed only on the digital audio signal.

FIG. 10 shows the frequency arrangement of these pilot signals, and FIG. 11 shows a detection circuit for detecting this pilot signal (f5) from the recording tape.

In FIG. 11, a composite signal reproduced by a head 30 is amplified by a head amplifier 31, and a bandpass filter (BPF) with the center frequency of the pilot signal (,f,) is used.
) 32 and extracts only the signal f5 through a detector (DET
) 33 performs level detection, and if this detection output is larger than the reference voltage Vr,1, the comparator 34 outputs a binary signal H (high).

If the signal f6 is detected while one of the six areas is being reproduced or searched, it can be determined that that area is the area where the digital audio signal is being recorded.

In conventional devices, it is possible to confirm that a multi-channel digital audio signal has been recorded only by using the signal f5. However, it is difficult to search for each recording on a tape with six channels by simply determining whether or not a digital audio signal is recorded.

Therefore, as mentioned above, information regarding channel changes,
It is desirable to write this as ID data at the time of recording.

FIG. 12 is a diagram showing an example of a setting pattern when setting how six programs are automatically recorded using a timer or the like. As shown in FIG. 12(a), it is possible to use six channels with six programs, one program per channel, and this is called a parallel setting pattern. In addition, as shown in 121ffi(b), as long as the first channel can accommodate programs from the first program to the sixth program, they are recorded in order, and if they cannot be accommodated in the first channel, the second program is recorded in program units.
It is also conceivable to move to the channel and record all programs up to the 6th program, and this is called a serial type setting pattern.

Although other patterns may be considered, the following problems occur no matter which setting pattern is used for recording.

That is, in the case of a multi-channel recording/reproducing apparatus, it takes a lot of effort to determine where on the tape the recording end point and the recording start point of a new channel are when switching channels. Therefore, it is conceivable to provide data related to channel change in the ID data to eliminate the above-mentioned inconvenience.

[Problem that the invention seeks to solve]

As mentioned above, in order to write data related to channel change in the ID data, manual operation is required in conventional devices, especially when performing automatic recording using a timer as described above. There was some confusion that it was difficult to record data related to channel changes.

This invention was made to solve this problem of m points, and it is easy to operate and can be written in multiple areas after recording.
An object of the present invention is to provide an information signal recording device that can facilitate searching of recorded information signals.

[Means for solving problems]

For this purpose, the information signal recording device according to the present invention includes first instruction information that instructs the change timing of the recording area, and second instruction information that instructs the recording area after the change according to the first instruction information. a storage means for storing instruction information, and prior to changing the recording area related to the first instruction information, the second instruction information
instruction information is recorded together with the information signal.

[For production]

By configuring as described above, data indicating the recording area after changing the recording area will always be recorded in the recording area before the change, making it easy to search after recording without performing complicated manual operations. Now I can do it.

〔Example〕

FIG. 1 is a diagram showing a schematic configuration of a tape recorder as an embodiment in which the present invention is applied to the above-mentioned multi-channel tape recorder. Figure 7 in Figure 1~
Components similar to those in FIG. 8 are given the same numbers.

PG obtained from the rotation detector 11 of the rotating cylinder 2 is supplied to the cylinder motor control circuit 16, which rotates the cylinder 2 at a predetermined rotational speed and a predetermined rotational phase. 12.
13 are 7 lie wheels 1 with capstan 14.15 respectively
7.18 rotation detectors, the outputs (FG) of which are alternatively supplied to a capstan motor control circuit 20 via a switch 19. The output of the circuit 20 is supplied to each capstan motor via a switch 21 so that the capstan 14 or 15 rotates at a predetermined speed during recording. Switches 19 and 21 are connected to the F side in the figure when the tape is run in the direction shown by arrow 7 (forward direction), and to the R side in the figure when the tape is made to run in the direction shown by arrow 9 (reverse direction).

By manually operating the operation unit 24, operation modes such as recording and reproduction, and areas to be recorded and reproduced are specified. It is also specified whether to record exclusively for audio or whether to record video signals as well using the recording pattern shown in FIG. Further, the track pitch and tape running direction during recording are also specified using this operation section 24.

Furthermore, when it is desired to change the playback channel as described above, the changed trunk number, tape running direction, and track pinch can also be specified using the operating section 24.

These data are supplied to the system controller 25, which controls the capstan motor control circuit 20, the switch 19.21, the area designation circuit 26,
It controls the gate circuit 27, ID signal control circuit 51, etc. Then, the area designation circuit 26 supplies the area designation data to the gate pulse generation circuit 23 to obtain a desired gate pulse.

Incidentally, in the case where a video signal is also recorded, the designated area is naturally CHI.

The control gate pulse of the gate circuit 28 is based on the area designation data, and is applied to the head 3. The aforementioned window pulses are selectively supplied to each of the heads 4.

During recording, the analog audio signal input from the terminal 29 is supplied to the PCM audio signal processing circuit 30, sampled at the above-described timing related to the window pulse, converted into digital data, and then subjected to the above-described signal processing. In addition, the above-mentioned ID data is also generated together with this audio data. The recording audio data obtained in this way is a pilot signal (TPS) for trackinder control that is generated from the high lot signal generation circuit 32 in a rotation of f1 → f2 → f, → f4 for each field.
and other pilot signals, which will be described later, in an adder 33. The output of the adder 33 is appropriately gated by the gate circuit 28 as described above, and written into a desired area by the head 3.4.

During playback, playback signals from the heads 3 and 4 are similarly extracted by the gate circuit 28 using window pulses, and this playback signal is passed through the A-side terminal of the switch 34 to a low-pass filter (
LPF) 35 as well as the PCM audio circuit 30.

Contrary to recording, the PCM audio circuit 30 performs signal processing such as error correction, time axis expansion, and digital-to-analog conversion, and outputs the reproduced analog audio signal to a terminal 36.
Output from

The LPF 35 separates the aforementioned TPS and supplies it to the ATF circuit 37. The ATF (Rackinder control) circuit 37 is a circuit for obtaining a tracking error signal using a well-known four-frequency method, and it combines the reproduced tracking pilot signal and the pilot signal generated by the pilot signal generation circuit 32 with the same rotation as during recording. It is well known that signals are used. However, since a tracking error signal is obtained for each region, this is sampled and held. The tracking error signal thus obtained is supplied to the capstan motor control circuit 2o, which controls the running of the tape 1 during playback via the capstans 14 and 15.
Performs tracking control.

Next, the function of recording and reproducing video signals will be explained.

When the system controller 25 issues a command to record and reproduce a video signal, the area designation circuit 26 is forced to
Specify the HI region and also set the gate circuit 27 to PGK.
Operate accordingly.

The video signal inputted from the terminal 38 is converted into a signal form suitable for recording by the video signal processing circuit 39 and sent to the post-adder 40.
supplied to Then, the adder 40 adds the pilot signal obtained from the pilot signal generation circuit 32, and the signal is added to the pilot signal obtained from the pilot signal generation circuit 32.
~CH6 is recorded. The recording operation of the PCM audio signal at this time is exactly the same as the recording operation described above for CHI.

During playback, video signals picked up by the heads 3 and 4 are converted into continuous signals via a gate circuit 27. This continuous number 15 is supplied to the video signal processing circuit 39, converted into the original signal form, and outputted from the terminal 41. Further, the continuous signal obtained from the gate circuit 27 is transmitted to the switch 34.
It is supplied to the LPF 35 via the V-side terminal of.

The LPF 35 continuously separates pilot signal components and supplies them to the ATF circuit 37. At this time, ATF circuit 3
The tracking error signal obtained from 7 does not need to be sampled and held, and is supplied as is to the capstan motor control circuit 20.

At this time, a PCM audio signal is also reproduced from the CHI area, and an analog audio reproduction signal is obtained from the terminal 36, but tracking control using the output signal of the gate circuit 28 is not performed.

ID0 to ID4 in FIG. 2 will be explained below with reference to FIGS. 3, 4, and 5.

IDO is a mode number indicating in which mode the word is written. Mode 7 is a mode exclusively for multi-channel digital audio recorders. The defined contents of IDI to ID, 1 differ depending on the mode number. ID5 is essential information and is common regardless of the mode. The details are shown in FIG. 5 for each bit and will be explained in detail later.

Next, IDO to ID4 in mode 7 for a multi-channel tape recorder will be explained below with reference to FIG.

In FIG. 3, the Oth to seventh bits of ■DO are used to indicate the mode number "7".

The seventh bit of IDI is a bit in which "0" is recorded during normal recording and "1" is recorded for a predetermined period (0.3 to 1.0 seconds) immediately before changing the recording area. The main points of this embodiment will be explained in detail below.

During normal recording, the seventh bit is "0", and at this time, the Oth bit indicates the running direction of the tape during recording, taking into account so-called reverse recording. Further, the first and second bits indicate the running speed at that time. The third bit is always set to "1". 4th. Fifth. The sixth bit indicates a signal used for searching recorded contents. On the other hand, immediately before changing the recording area, the 7th bit is set to “
1".

The 7th bit is set to 1 before changing the recording area.
This is the period from 0.3 seconds to 0.3 seconds before the end of recording for the area currently being recorded.
When the bit is "1", the 0th bit indicates the running direction of the tape during recording, as in normal recording. Indicates the number of the recording area after changing the first to third bits. The fourth bit is always set to "1". The 5th bit is after changing the recording area.
Indicates the position in the longitudinal direction of the tape where recording begins.

In other words, this is information for identifying whether to start recording from the position immediately before the change, or from one end of the tape.

The sixth bit indicates the running direction of the tape after changing the recording area.

Next, ID2 and ID3 use the year, month, day, day of the week, and hour, minute, and second as necessary, mainly using the seventh bit as a control pit. ID4 indicates the program number or C number ((:apterS(:ut, (generic term for:ue) from 0 to 79.

In addition, Pro〆NO in Figure 4 is the program number, Cut/
NO indicates the cut number, and Frame/No indicates the frame number.

The information indicated by the 8-bit data indicated by Y in FIG. 4 is shown in FIG. Y indicates data of ID5 in each mode of 1 to 7. The Oth bit of this data Y indicates whether this 8-bit data Y itself is valid or invalid. 1st. The second bit indicates the format of the audio signal, such as whether the audio information recorded in the two channels is monaural or stereo. Also the third. The fourth bit provides audio signal information to the first channel and second channel corresponding sections, respectively.

Indicates whether to record information or other information.

Also, the fifth. The 6th bit is the recording start part of the audio signal,
The data becomes "1" at the end of recording, and the seventh bit becomes "1" when it is desired to prevent dubbing.

Next, the recording of such ID data will be briefly explained.

FIG. 6 is a diagram showing a specific example of the PCM audio signal processing circuit in FIG. 1. In FIG. 6, 101 is a terminal to which the input analog audio signal input to the terminal 29 is supplied, and 102 is a terminal to which output data from the ID control circuit 51 is supplied. The parallel data supplied to the terminal 102 is supplied to the ID generation circuit 104, which generates serialized data at a predetermined timing.

On the other hand, an analog audio signal input to the terminal 101 is supplied to an analog-digital converter (A/D) 103. The A/D 103 samples the analog audio signal at a predetermined frequency, quantizes it, and supplies it to the data selector 105 as serial data at a predetermined timing. The data selector 105 selects the ID data generating circuit 10 once per field period at a timing corresponding to the IDI.
4 is supplied to the RAM (random access memory) 107, and at other timings, the output of the A/D 103 is supplied to the R
Supply to AMI 07. The RAM 107 stores the parity word (P) obtained from the error correction circuit (ECC) 106.
, Q), CRCC, etc., address data obtained from the address controller 108, and data obtained from the data selector 105 described above are arranged so as to correspond to the data matrix shown in FIG. From the RAM 107, the time-base compressed data is supplied to the modulation circuit 109 in the order described in 11. Output. The digitally modulated audio signal output from the terminal 111 is supplied to the adder circuit 33 as described above.

Next, the operation during playback will be explained. A digital modulation signal sent to the terminal 112 via the gate circuit 28 is demodulated by the digital demodulator 113 and supplied to the RAM 115.

RAMI 15 performs signal processing that is completely opposite to that of RAM 107. That is, the arrangement is changed based on the address data obtained from the address controller 114 and further on the synchronization data, and error correction is performed in the ECC 116. Also,
Along with this, each data of the D1 column and D2 column obtained is RA
It is output from M115 and supplied to a D/A (digital-to-analog converter) 117 and a data reading circuit 118.

1) /A117 restores the original analog audio signal and outputs it from the terminal 36 in FIG. 6 via the terminal 119. On the other hand, the data reading circuit 118 performs a big amplification on the above-mentioned ID data and supplies it to the ID detection circuit 52. Furthermore, the 9th
It is assumed that the operations of each part of the signal processing circuit shown in the figure are all synchronized by a timing signal generated by the timing controller 110.

The ID detection circuit 52 supplies information as shown in FIGS. 1, 7, and 8 to the system controller 25 for ID data retrieval. According to these data, the system controller 25 controls the area designation circuit 26 and the capstan control circuit 20.

Next, the operation of timer recording in the tape recorder of this embodiment will be explained.

In FIG. 1, the operation unit 24 is used to set a timer recording program. Timer device 60 stores its program contents in memory 61. The stored data items include, for example, a program number, start date and time, end date and time, input number, recording channel number, and a jump flag to be described later. It is conceivable that some of this information may not be directly input as data from the operation unit. In other words, the jump flag is set to H (high) when the recording area is to be changed when the currently recorded program ends; otherwise, the jump flag is set to L (low) when the next program is also to be recorded in the same area. ) is set as 1-bit information, this information may be set manually from the operation unit 24 when setting the timer.
It is also possible to automatically set it using the system controller 25 based on information such as the remaining amount of tape.

In this way, the timer device e60 sends a recording start command, a stop command, etc. to the system controller 25 based on the data stored in the memory 6I.

The system controller 25 receives these commands, controls each part of the tape recorder, and performs timer recording.

Next, if you have read the jump flag of the program that started recording, you can execute the stop operation at the end time and then wait for the next program to run. Also, if the jump flag is H, the jump flag is 1 second before the end time, or from 1 second to 03 seconds before the end time according to the end time data included in the first instruction information of the present invention stored in the memory. At any timing, the information regarding the change of the recording area
Start recording the D data.

The content written in the ID data needs to include at least the recording channel number of the next program included in the second instruction information in the present invention. In addition, of course, each data set in the above-mentioned mode 7 is recorded.

When writing ID data related to this change in the recording area, the system controller 25 first requests the timer device eoKw to read the jump flag, reads it from the memory 61, and confirms that the jump flag is H. . Next, in the same way, what is the recording channel number after changing the recording channel? The system controller 25 reads the data containing at most J>. The read data is converted to match the format shown in FIG. 3 and recorded as ID data together with digital audio data. The system controller 25 mentioned above at this time
The operation is shown in the flowchart of FIG.

In addition, after starting recording of ID data related to changing the recording area, 1
Recording stops after a second, but in this state, instead of waiting for the next program execution, the area designation circuit 26 is activated by the previously read data indicating the changed recording area, and then it waits. .

This is because, in the event that separate recording is performed in the standby state, unrelated to the next program, it is impossible to rewrite only the data, so there will be a discrepancy between the contents of the recorded ID data and the actual recording state. This is because there is a possibility.

Furthermore, 1. Read the data indicating the running direction and starting position of the tape after changing the area, that is, the 5th and 6th bits of mode 7 in the ID data, change the specified area, and move the tape according to the above data. It is desirable to carry out the process and even perform positioning.

This is because the time required for tape transport is uncertain.
Change the specified area and position the tape first.
This is also desirable from the standpoint of accurately determining the recording start timing.

As described above, ID data, which had conventionally been entered manually, can now be automatically recorded during timer recording.

〔Effect of the invention〕

As described above, the present invention is capable of recording a changed recording area before changing the recording area, so that an information signal that allows the user to easily search for recorded information without requiring the user to perform any troublesome operations is provided. An information signal recording device capable of recording can be obtained.
