BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing device.

[0002]

2. Description of the Related Art In a conventional magnetic recording / reproducing apparatus, 1
January 989 Electronic Store PP. 54-55 As described in Denpa Shimbun, when the television program currently being viewed becomes unviewable for some reason and there is a need to immediately record the rest of the television program, the recording operation of the recording is performed. The end time is set to the present time or a specific time from the recording operation end time registration to the recording operation end time.

[0003]

In the above-mentioned conventional magnetic recording / reproducing apparatus, the reason why the necessity of recording immediately and leaving the place is overly emphasized is that the recording operation is completed from the present time to the end of the recording operation. The time from the time registration to the end time of the recording operation is set using a stepwise specific time, such as every 30 minutes, prepared in advance so as to avoid troublesome time calculation. There was such a problem.

1) Even if the recording time after registration of the present time or the recording operation end time is 35 minutes, for example, 30
If you can only set every minute, you must set it to 60 minutes. Therefore, an unnecessary recording portion of 25 minutes is generated on the recording tape.

2) According to 1), when there is reserved recording after the recording is completed, in some cases, the remaining amount of the recording tape is small, so that all or part of the unrecorded recording occurs.

3) In order to prevent the phenomenon of 2), it becomes necessary to replace the magnetic recording tape after the recording is completed, and the user completely leaves the magnetic recording / reproducing device after the recording operation end time is registered. I can't do that.

As described above, the prior art does not consider the supply amount of the magnetic recording tape for the reserved recording after the end of the recording operation. An object of the present invention is to set a recording operation end time at which the recording ends during the recording operation, thereby eliminating unnecessary recording portions on the magnetic recording tape, and suppressing the phenomenon described in 2) and 3) above. It is to provide a recording / reproducing apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1 as a known example, FIG. 2 which is a conventional method in a recording operation ending procedure of a home video tape recorder (hereinafter abbreviated as VTR) is an embodiment of claim 1 according to the present invention. explain. A block diagram of the hardware of the present invention is shown in FIG. Originally, in order to make a reservation for the end of the recording operation being performed by the VTR at the current time, the procedure shown in FIG. 2 is performed, and the information storage unit 2 connected to the operation control computer 1 that controls the operation of the VTR is required. It is necessary to input various information using the information input device 3 including keys. Here, a conventional recording operation end time reservation procedure during recording at the current time will be described below. The numbers at the beginning of the following explanations match the numbers of the respective procedure items in FIG.

1 Recording operation end reservation mode: The VTR is switched from the normal operation state to the recording operation end reservation mode in order to initially set the recording operation end reservation. At this time, the display 4 for displaying the operating state of the VTR, which is generally formed on the entire surface of the VTR, is in the state shown in FIG. 4, and the operation item to be performed next is for the recording operation end reservation setting person. For indicating, it is in a blinking state or the like. Here, the recording completion time display section 9 is in a blinking state.

2 Recording operation end time setting ... The end time of the recording operation of the recorded program being recorded at the current time is selected by inputting the time from the current time to the end time from a specific time which is determined stepwise. For example, the current time and end time are 21
Hours 10 minutes, 21:45 and the specific time is 30, 60,
If it is desired to end the recording operation at the desired end time when the time is 90 or 120 minutes, the specific time is at least 60.
More than a minute. Therefore, here, 60 minutes is selected by using some information input means such as a key. Here, the display 4 is in the state shown in FIG. When 120 minutes is selected, the presence of a: (colon) between "hour" and "minute" in the recording end time display section 9 is difficult for the user to understand, so it is deleted here. .

3 Recording operation end time registration: The recording operation end time information set in the above item 2 is registered by some information input means including a key. The display 4 becomes the state of FIG. 6 and the blinking of the recording completion time display portion 9 stops. This completes the recording operation end time reservation procedure, and the recording operation of the recorded program being recorded at the current time ends at the registered recording operation end time. The method described in the recording operation end time reservation procedure is not limited to this. here,
Only the general recording operation end time reservation procedure was used. next,
Consider a case in which the reservation recording registration after the recording operation of the recorded program already recorded at the current time is completed before the current time. Here, the reserved recording start time and the reserved recording end time are respectively 1:00, 2:15, that is, 75 minutes of the reserved recording time. In this case, when continuously recording from the head of the magnetic recording tape to the magnetic recording tape capable of recording the recorded program and the reserved recording at the standard speed for 120 minutes at the current time, the recording target at the current time is recorded. Since the recording time of the recorded program is 60 minutes as described above, if the recording speed is the standard speed, an unrecorded portion of 15 minutes will occur. Therefore, in order to completely record the reserved recording at the standard speed, the setting in the conventional recording operation end time reservation procedure item 2 is set to 30 minutes, or the recording operation of the recorded program being recorded at the current time ends. Later, it was necessary to replace the magnetic recording tape. What is particularly problematic here is that the user cannot completely set the VT after setting the recording operation end time.
It is impossible to leave R. This is very inconvenient for a user who originally has been unable to watch a television program or the like that he has been watching until now, and needs to record the rest on the VTR and leave the place. .

The above problem is solved by an embodiment of the present invention shown in FIG. Hereinafter, FIG. 1 will be described. still,
The numbers at the beginning of the following explanations match the numbers of the respective procedure items in Fig. 1. Since the procedure of item 1 is the same as that of item 1 of FIG. 2, the description is omitted here.

2 Setting end time of recording operation: The end time of the recording operation of the recorded program being recorded at the current time is set.
The end time of 21:45 is set by some information input means including a key. Here, the display 4 is as shown in FIG. Also, in the recording completion time display section 9: (colon)
Is used for time display.

3 Recording operation end time registration: The recording operation end time information set in the above item 2 is registered by some information input means including a key. The display 4 is in the state shown in FIG. 8 and the blinking of the recording completion time display section 9 is stopped.

As described above, according to the present invention, the setting of the end time does not select and input the time from the current time to the end time from the specific time which is determined stepwise, but the end time itself is set and registered. Therefore, it is possible to prevent the unnecessary recording portion from being generated on the magnetic recording tape, and the supply capability of the magnetic recording tape for later reserved recording is improved. In this case, when the recorded program and the reserved recording which are being recorded at the current time are continuously recorded from the head of the magnetic recording tape to the magnetic recording tape capable of recording 120 minutes at the standard speed, if the recording speed is the standard speed. A recording time of 110 minutes is sufficient, and the occurrence of unrecorded portions as in the conventional case can be suppressed to a low level. Although there are changes in the recording operation end time setting method, display, etc., in implementing the present invention, most of the present invention is easily entrusted to the software of the operation control computer 1 in the VTR. It is feasible.

[0018]

As described above, according to the present invention, since the recording operation of the recorded program being recorded at the current time is completed by registering an arbitrary recording operation end time, the magnetic recording tape. This has the effect of eliminating the unnecessary recording section above. As a result, the supply capacity of the magnetic recording tape for the reserved recording after the recording operation of the recorded program being recorded at the current time registered before the current time is improved, and the necessity of replacing the magnetic recording tape is reduced. The user can completely leave the magnetic recording / reproducing apparatus after the recording operation end time of the recorded program being recorded at the current time is reserved.
