Abstract

PURPOSE:To attain consecutive recording for a long time by providing 1st and 2nd magnetic recording and reproducing device so as to start the recording on to a 2nd cassette tape after the signal recording to a 1st cassette tape is finished. CONSTITUTION:Two VTRs 8, 13 are connected mutually via connecting means 7 and 15. At the video recording end time or just before the time, a signal to start video recording is sent from a control means 15 of the VTR 8 to a control means 11 of the VTR 13, a recording/reproducing means 10 starts its operation by a command from the means 11 and a television signal 14 is recorded on a cassette tape 9. When the tape is used out on the way of video recording, as soon as the tape traveling is stopped, a signal starting the video recording is sent from the means 15 to the means 11 and the recording on the tape 9 is reproduced. Thus, the video recording of a television program is not finished on its half way and the scheduled video recording on the program is attained to its end.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a magnetic recording/reproducing device that can automatically extend recording time.

BACKGROUND OF THE INVENTION There are two methods for recording television programs on a consumer VTR using cassette tapes. There are two methods: recording starts as soon as you press the record button, and ends when you press the button or when the tape is used up, and timer recording. Timer recording is performed as follows. When the date and time to start recording, time to end recording, channel to record, recording mode, etc. are set and timer recording mode is set, the built-in timer will start recording according to the set recording time using the built-in clock. It determines the start date and time and automatically starts recording the TV program at a predetermined time. Similarly,
When the set recording end time is reached, recording will automatically end.

FIG. 2 shows a method of recording a television program using a conventional magnetic recording/reproducing device.

(For example, "Television Technology" August 1983 issue pp47-53
) A television signal 14 transmitted from a broadcasting station is received by the tuner 6 of the VTR 8. Here, when the recording start button on the operation unit 3 is pressed, the signal 14 received at 6 is converted to a video signal via the signal processing circuit 5, and is recorded on the cassette tape 1 via the recording/playback means 2. .

On the other hand, when performing timer recording, the recording start time, end time, reception channel, etc. are set in advance using the timer recording setting button on the operation unit 3, and the timer recording start switch is set.

When the clock in timer part 4 reaches the recording start time,
The signal 14 being received at 6 begins to be recorded on the cassette tape 1 via 5.2. Furthermore, when the clock in 4 reaches the recording end time, recording stops.

In such a VTR, if the remaining capacity of the tape is shorter than the scheduled recording time, or if the scheduled broadcast time of a television program is delayed, recording ends in the middle of the program.

Problems to be Solved by the Invention In this way, by starting recording without checking the remaining amount of tape, the tape runs out before the program scheduled for recording ends, and recording ends in the middle of the program. It may end. Or, if you try to record a TV program using the timer recording function, but the program is extended for some reason, the program that was scheduled to be recorded is still being broadcast even after the scheduled recording end time. Yes, you cannot record to the end. Further, even if a program earlier than the program scheduled to be recorded is extended, there is a problem in that the scheduled program cannot be recorded to the end.

Means for Solving the Problems Accordingly, the present invention provides a first magnetic recording and reproducing device comprising a first recording and reproducing means for recording and reproducing video signals on a first cassette tape; a second magnetic recording and reproducing device connected to the reproducing device and equipped with a second recording and reproducing means for recording and reproducing video signals on a second cassette tape, the first magnetic recording and reproducing device comprising: The recording and reproducing device includes a first connecting means connected to the second magnetic recording and reproducing device, and a first connecting means that connects the signal to the second cassette tape at the same time as or immediately before the recording of the signal on the first cassette tape ends. a first control means for operating a second magnetic recording and reproducing device to start recording, the second magnetic recording and reproducing device comprising a second connecting means connected to the first connecting means; , a second control means for receiving control information from the control means and controlling the second recording/reproducing means.

Effect: With this configuration, when the remaining tape capacity is low and recording is about to end in the middle of a program, or when the broadcast time is extended, the end time of a program that was attempted to be recorded using a timer is pushed back. Sometimes the recording time can be extended.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

The operation of the magnetic recording and reproducing apparatus according to the present invention will be explained with reference to the drawings.

FIG. 1 shows a method of recording a television program by means of a magnetic recording and reproducing apparatus according to the present invention.

In FIG. 1, the same parts as in FIG. 2 are given the same numbers. Here, two VTRs 8 and 13 are connected to each other via coupling means 7 and 12.

When performing timer recording with the VTR shown in Figure 1, timer recording is set using the button on the operation unit 3, as in the case of Figure 2, and when the clock on the timer section 4 reaches the recording start time, recording starts. Begins. Then, at or just before the recording end time, a signal to start recording is transmitted from the control means 15 of the VTR 8 (7) to the control means 11 of the VTR 13 (7), and the recording and reproducing means 10 starts operating according to a command from the control means 11. Initially, the television signal 14 is recorded on the cassette tape 9. The cassette tape 9 does not need to be of the same type as the cassette tape 1, and may be any tape that can record for a desired extended period of time.

Next, start recording by pressing the record button, and if the tape runs out during recording, at the same time as the tape stops running, a signal to start recording is transmitted from the control means 5 to the control means 11, and the cassette tape is 9 starts recording. However, in this case, some time is required from when it is detected that the tape has stopped running until recording to the cassette tape 9 starts, so it is not possible to record the television signal during that time. . To prevent this, it is necessary to replace the operation section 3 of the VTR 8 with the same operation section as the operation section 3 of the VTR 8.
3, it is possible to press the record button and start recording on the cassette tape 9 before the tape running of the cassette tape 1 stops.

Effects of the Invention As described above, according to the present invention, recording of a television program does not end midway, and a scheduled program can be recorded to the end.

Furthermore, since recording is performed continuously on two cassette tapes, continuous recording can be performed for a longer period of time than when only one cassette tape is used.
