For example, the present invention is suitably applied to consumer electronic devices such as a video tape recorder for recording and reproducing programs.

B. Summary of the Invention According to the present invention, erasure permission or erasure prohibition is set for each program of a program recorded on the downstream side by using erasure permission information or erasure prohibition information recorded at the head of the tape of the tape-shaped recording medium. When the information that specifies the deletion permission is obtained, the program is easily deleted by generating new information that specifies the deletion permission or deletion prohibition based on the recording prohibition / permission information obtained from the cassette. The permission or erasure prohibition state can be controlled.

C Conventional Techniques When recording a plurality of programs on a video tape extending in the longitudinal direction, a conventional consumer video tape recorder records a cue signal at the beginning of each program.
For example, when the user wants to play a desired program from a recorded tape, the video tape recorder is set to the search mode once, the video tape is fast-forwarded to a position where the cue signal can be reproduced, and then temporarily switched to the playback mode. It is designed to check whether the program is desired to be watched.

D Problems to be Solved by the Invention By the way, in this type of video tape recorder,
A nail for preventing erroneous erasure is provided on the housing of the video cassette, and by breaking the nail, control is performed such that a video recording operation is prohibited for the video cassette.

Therefore, even if the video cassette in which the nail for preventing erroneous erasure is broken is loaded into the video tape recorder to execute the recording mode, the video tape recorder does not start the recording operation.

However, once the nail for preventing erroneous erasure is folded and the erasure is prohibited once, when the video cassette is again set to the erasure permission state, complicated work such as sticking an adhesive tape or the like instead of the folded nail is required. In addition, the video cassette in which the nail for preventing erroneous erasure is not broken cannot be put into the erasure prohibiting state while being loaded in the video tape recorder main body.

The present invention has been made in view of the above points, and it is an object of the present invention to propose a recording / reproducing apparatus capable of designating an erasure permission or an erasure prohibition state preferentially with respect to an erroneous erasure prevention nail state. It is.

In step SP26, the CPU 8 executes the program information D _PRX (the sixth
The category code data recorded in item B6 of FIG. 7 can be rewritten.

Further, the CPU 8 can rewrite the title data recorded in the item B12 of the program information D _PRX (FIG. 6) in step SP27.

After rewriting the data of the "password" item to the "title" item in steps SP23 to SP27 in this way, when the "end" item is specified in step SP28, the CPU 8 ends the processing of the management database and proceeds to step SP29. Then, the process returns to the management database processing loop shown in FIG. 7 to enter the processing of step SP8.

On the other hand, if the user clicks the "cancel reservation" item in the command standby state in which the management data list is displayed in step SP21 of FIG. 8, the CPU 8 proceeds to step SP21.
In SP30, all program reservations recorded in the management data list are canceled.

Also, when the user clicks on the "auto play" item,
The CPU 8 determines the volume information D _VMX (step 5) in step SP31.
The reproduction order data of the item A13 shown in the figure) is reproduced in a fixed order and rewritten as necessary.

When the user clicks the "manual reservation" item, the CPU 8 sequentially accepts manual settings for a predetermined number of programs in step SP32 and inputs them as management data.

When the processing of steps SP30, SP31 and SP32 ends, the CP
U8 returns to the management database processing loop (FIG. 7) through the above-mentioned steps SP28 and SP29.

When the user clicks the "program information confirmation" item in the command standby state for displaying the management data list in step SP21 of FIG. 8, the CPU 8 enters the processing of step SP33 and displays the display screen in step SP34. Switch the display of step SP35 or SP36 or SP3
7, or SP38, the recorded contents of the "recording permitted" item, the "watch flag" item, the "category" item, and the "title" item of the volume information D _VMX (FIG. 5) and the program information D _PRX (FIG. 6) Becomes a display mode in which can be confirmed or rewritten.

In the case of this embodiment, a predetermined picture display, that is, a character is used as the data of the “recording permission” item, the “seen flag” item, the “category” item, and the “title” item, so that the display area is relatively small. Thus, information recorded on a plurality of reserved programs can be confirmed and changed.

When the processing of steps SP35 to SP38 is completed, the CP
U8 returns to the management database processing loop (FIG. 7) via steps SP28 and SP29.

Further, in the command standby letter displaying the management data list (step SP21), the user sets “management data reservation”.
When you click on an item, the CPU 8 executes the management data subroutine.
It enters the RT3 and executes a management data reservation processing procedure RT31 for switching the reservation mode as shown in FIG. 9, which constitutes a part of the processing procedure.

At this time, the CPU 8 allows the user to select the timer reservation mode in step SP41.

In the case of this embodiment, as a specification item list that can be presented to let the user specify and select the specification item of the management data,
As shown in FIG. 11, a word specification item list table TBL consisting of word input items representing the specification item using natural language, and the specification item is represented using graphic elements such as Roman letters, numbers, symbols, etc. as usual. A graphic specification item list, which is a graphic input item, is prepared. At step SP41, the CPU 8 allows the user to select and specify either a word input or a graphic input as a reservation screen to be used.

As a result, when the word input is selected, the CPU 8 executes the step.
The process proceeds to SP42, where the word designation item list TBL is displayed on the display screen, and the data corresponding to the word entry item designated by the user is loaded into the register 44.

Conversely, if graphic input is selected, CP
U8 proceeds to step SP43 to display a graphic specification item list on the display screen, and fetches data corresponding to the graphic input item specified and operated by the user into the register 44.

Thus, when the user's designation input operation is completed, the CPU 8 ends the management data reservation input processing and returns to the processing loop of the management database in FIG.

At this time, the CPU 8 subsequently displays a “register” item, a “change” item, and an “inquiry” item on the display screen, and proceeds to step SP51,
In SP52 and SP53, the user clicks on the "registration" item, "change" item, or "inquiry" item to enter a process of executing this.

Here, in processing the clicked item, the CPU 8 can display the calendar reservation table, the weekly reservation table, and the daily reservation table in steps SP54, SP55, and SP56, respectively, according to the user's selection. The start time and / or end time of the reserved program is written on a calendar reservation table, a one-week reservation table, or a one-day reservation table.

When such processing is completed, the CPU 8 terminates the processing program of the management database in the above-mentioned step SP28,
Step SP29 to the management database processing loop (7th
Return to figure).

The above steps are performed in the initial command standby state shown in FIG.
In SP6, the management data is recorded, changed, and confirmed on the videotape by clicking the "management database" item. In the initial command standby state, other specified items, that is, the "system setting" item Or, when the user clicks the item of “preference setting” or the item of “timer reservation”, the CPU 8 executes a process of setting operating conditions of each unit of the video tape recorder 1.

That is, when the user clicks "system setting" in step SP61 of FIG. 7, the "current time" item, the "sleep timer" item, and the "recording mode" are displayed on the display screen.
Item, "Noise Elimination" item, "BS Online" item,
The “Auto-set” item, the “Preset” item and the “Line input” item are displayed, and these items are changed to steps SP62, SP63, SP64, SP65, SP66, SP67, SP
By clicking at 68 or SP69, the operating conditions of each part of the system can be set. When the setting processing is completed, the CPU 8 ends the system setting processing loop and proceeds to the above-mentioned step SP10.

On the other hand, when the CPU 8 clicks the “Preference setting” item in step SP71, the “screen display” item, “management database” item, “user set” item, “character” item, and “timer reservation” item are displayed on the display screen. "item,
The "user level" item, the "message" item and the "voice" item are displayed on the display screen, and these items are step SP72, SP73, SP74, SP75, SP76, SP77, SP, respectively.
When clicked at 78 or SP79, the CPU 8 executes the processing of each item, and when the processing is completed, proceeds to the above-mentioned step SP10.

Further, in the initial command standby state, when the user clicks the “timer reservation” item in the subsequent step SP81, the CPU 8 displays the “registration” item, the “change” item, and the “inquiry” item on the display screen, and the user Step SP82, SP83
Alternatively, when each item is clicked in SP84, the “calendar reservation table” item, “one week reservation table” item, and “one day reservation table” item are displayed on the display screen. Subsequently, when the user specifies one of them, the CPU 8 executes steps SP85 and SP85.
At 86 or SP87, a calendar reservation table, a one-week reservation table, or a one-day reservation table is displayed, and a program is reserved using the reservation table.

When the CPU 8 finishes the processing of the timer reservation processing loop, it proceeds to the above-mentioned step SP10.

By executing the input information processing program RT0 in FIG. 7 in this way, the CPU 8 can reliably control the video tape recorder main body 3 based on the input data input by the user.

(G5) disposed in the management database audio tiger poke recording region F _AVA or management database video tiger poke recording region F _AVV management data D _AV recorded in the Boriyumu information D _VMX items A9 recording permission / inhibition processing operations videotape 36 If the “recording prohibition flag” of the “various flags” is designated as a recording prohibition state by the user, the CPU 8 sets the state of the erroneous erasure prevention nail provided on the housing of the video cassette 35. , The video tape 36 of the video cassette 35 can be controlled to be in the erase-prohibited state.

That is, when the user performs the recording or the recording reservation operation of the video tape recorder 1, the control data processing CPU 8 detects the state of the nail for preventing erroneous erasure of the loaded video cassette 35 through the mechanism control CPU 11, and First
Execute the recording permission / prohibition processing routine RT71 shown in FIG.
It is determined whether or not recording is allowed.

That is, this recording permission / prohibition processing routine RT71
8 shows the recording permission prohibition processing operation in the input information processing and management database setting processing shown in FIG. 8 and FIG. 8, and in step SP140, step SP35 shown in FIG.
By executing the processing operation includes reads the management data D _AV recorded on the video tape 36 from the Boriyumu information D _VMX of the management data D _AV in the "flags", "recording inhibit flag Is in a prohibited state.

If a positive result is obtained here, this means that the program must not be newly recorded on the video tape 36 (that is, the program recorded on the video tape 36 must not be deleted). In the following step SP141, the CPU 8 executes the video tape recorder main body 3
Is controlled to be in the recording prohibition state, and in step SP144, the process proceeds to step SP28 shown in FIG. 8 to end the processing routine.

On the other hand, if a negative result is obtained in step SP140, this means that the program may be newly recorded on the video tape 36 (that is, the program recorded on the video tape 36 may be deleted). At this time, the CPU 8 proceeds to step SP142 to change the state of the nail for preventing erroneous erasure provided on the casing of the video cassette 35 into the erase-inhibited state (that is, the state where the nail is broken). )
Or the erase permission state (ie, the state in which the nail is not broken). If it is determined that the erasure is prohibited, the CPU 8 proceeds to step SP141 to record the video tape recorder main body 3. Control to the prohibited state.

On the other hand, if it is determined that the erase
Moves to the next step SP143, and controls the video tape recorder main body 3 to be in the recording permission state.
Then, the processing operation is terminated by moving to the processing of step SP28 shown in FIG.

Thus CPU8 If the state of the recording inhibit flag of the management data D _AV recorded on the video tape 36 is a recording disabled state, the state of the pawl for erroneous erasure prevention provided on the housing of the video cassette 35 Irrespective of this, the video tape recorder main body 3 can be controlled to the recording prohibited state.

Here, the CPU 8 executes the recording permission / prohibition determination processing routine RT81 shown in FIG. 13 when determining the state of the recording prohibition flag in step SP140.

That is, the CPU 8 reads out the management data D _AV recorded on the video tape 36 of the video cassette 35 loaded in the video tape recorder main body 3 in step SP150,
"Recording inhibit flag" included in the "flags" from the Boriyumu information D _VMX of the management data D _AV determines whether summer prohibited state at next step SP151.

If a positive result is obtained here, this means that the program recorded on the video tape 36 must not be erased (that is, the program must not be newly recorded on the video tape 36). In the following step SP152, the CPU 8 sets the "recording permission" internal flag of the video tape recorder main body 3 provided for each program recorded on the video tape 36 to "recording permission" as an initial state. The state is switched from the state to the “recording prohibited” state, and the display screen 4A is displayed in the next step SP153.
And the record prohibition state is indicated by a pictorial display on 6A.

On the other hand, if a negative result is obtained, this means that the program may be newly recorded in the area where the program is recorded on the video tape 36 (that is, the program recorded on the video tape 36 is deleted). The CPU 8 jumps to the next step SP152 and skips step S152.
In P153, a pictorial display indicating the recording permission state is displayed on the display screens 4A and 6A.

Thus, the CPU 8 displays on the display screens 4A and 6A whether or not all the programs recorded on the video tape 36 of the loaded video cassette 35 can be erased, and when the erasure is prohibited, Even if the user attempts to record a new program on the video tape 36, this is not executed.

Thus, the CPU 8 moves to step SP154 and returns to step SP140 of the above-described recording permission / prohibition processing routine RT71.

Therefore, the user operates the management data D _AV of the video tape 36 of the loaded video cassette 35 on the display screens 4A and 6A.
It is possible to confirm whether the recording is in the recording permission state or the recording prohibition state, and in the recording permission state, the program can be newly recorded.

According to the above configuration, the management data D is given priority over the state of the nail for preventing erroneous erasure provided on the housing of the video cassette 35.
By you to specify by connexion recording disabled state (ie erased disabled state) in _AV, management data D _AV by can record prohibition specified with recording reservation or the like other operations, to further improve the usability of the user In addition, erroneous erasure can be reliably prevented.

(G6) Other Embodiments (1) In the above embodiment, when the recording prohibition flag is in the recording permission state, the state of the nail for preventing erroneous erasure provided on the housing of the video cassette 35 is checked. However, the present invention is not limited to these, and recording permission or recording prohibition may be designated only by the state of the recording prohibition flag as necessary.

In this case, the recording permission / prohibition processing routine RT shown in FIG.
By executing step 91, it is possible to select a processing mode that takes account of the nail for preventing erroneous erasure or a processing mode that depends only on the state of the recording prohibition flag.

That is, the control management data processing CPU 8 selects the recording permission or prohibition only in the processing mode 1 in consideration of the nail for preventing erroneous erasure or the state of the recording prohibition flag only in step SP160 of the recording permission / prohibition processing routine RT91. Mode 2 is selected according to the user's instruction.

Here, when the processing mode 1 is selected, the CPU 8 executes the above steps in the following steps SP161, SP162, SP163, and SP164.
After performing the same processing as the processing of SP140, SP141, SP142, and SP143 to control the video tape recorder main body 3 to the recording permission or recording prohibition state, the processing routine RT91 is ended in step SP165.

On the other hand, if the processing mode 2 is selected in the above-mentioned step SP160, the CPU 8 moves to the step SP166 and executes the same processing as the above-mentioned step SP140 to determine whether the state of the recording inhibition flag is the recording inhibition state. Judge whether or not
If an affirmative result is obtained, the process proceeds to step SP162 to control the video tape recorder main body 3 to the recording prohibition state, and then, in step SP165, the process proceeds to step SP28 shown in FIG. 8 to terminate the processing routine RT91.

On the other hand, if a negative result is obtained, the CPU 8 shifts to the above-mentioned step SP164 to control the video tape recorder main body 3 to be in the recording permission state, and then, at step SP165, the eighth step.
The processing routine RT91 ends by moving to the processing of step SP28 shown in the figure.

Therefore, when the processing mode 2 is selected, the CPU 8 controls the video tape recorder main body 3 only by the state of the recording prohibition flag, not by the state of the nail for preventing erroneous erasure provided on the casing of the video cassette 35. It can be controlled to a recording permission (that is, erasing permission) or a recording prohibition (that is, erasing prohibition) state. For example, the nail for preventing erroneous erasure of the video cassette 35 is broken, and the video cassette 35 is in an erasing prohibition state. Even in the state, the video cassette 35 of the video cassette
By changing the recording inhibit flag of the management data D _AV recorded in the recording enabled state 36, the video tape
36 programs can be recorded.

(2) In the above-described embodiment, the case where the status of the recording prohibition flag is visually displayed has been described. However, the present invention is not limited to this, and the status may be indicated by voice or the like.

(3) In the above-described embodiment, the management data D _AV is configured so that the volume information block D _VM and the program information block D _PR are written in that order from the head position of the recording track. Various changes may be made, such as changing the order of the arrangement or, if necessary, mixing the pieces in a finely divided manner.

(4) In the above-described embodiment, the case where the present invention is applied to a video tape recorder has been described. Alternatively, other various recording / reproduction such as a case where an audio signal is recorded like a so-called boombox. The present invention can be applied to the device in the same manner as described above.

H Effects of the Invention As described above, according to the present invention, information for designating erasure permission or erasure prohibition is recorded for each recorded program at the beginning of the tape of the tape-shaped recording medium. By simply reproducing the head of the tape of the recording medium, a program to be deleted or a program that should not be deleted can be more easily notified to the operator,
When the information for specifying the erasure permission is obtained, the information for newly specifying the erasure permission or the erasure prohibition is generated based on the recording prohibition / permission information obtained from the cassette. It can be used effectively.
