Abstract

PURPOSE:To equalize the recording time mode of a recording side to the recording time mode of the recorded tape of a reproducing side by detecting the recording time mode of the recorded tape by a reproducing device and matching the recording time mode of a recording device with the recording time mode of the recorded tape according to the detection signal. CONSTITUTION:The recording-side deck includes the same elements 2a-2l with 1a-1l and the same SWs 4-6 with SWs 1-SW 3. The Sws 4 and 5, however, are set on sides REC in dubbing and editing mode. An SW 7 is a manual/automatic changeover switch for the recording time mode of the recording-side deck during dubbing and editing and this switch is placed normally at its automatic side; and the recording time mode control signal 1m is sent to the capstan motor control part 2j of the recording side during the dubbing and editing, so that the recording side and reproducing side perform recording operation in the same recording time mode. Thus, the recording time mode control signal 1m of the reproducing side is sent to the recording-side deck R to set the recording time mode of the recording-side deck R to the same mode with the reproducing-side deck automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording and reproducing apparatus used for dubbing and editing video tapes.

2. Description of the Related Art In recent years, many magnetic recording and reproducing devices equipped with dubbing and editing capabilities have been produced. Dubbing and editing with a home video tape recorder (hereinafter referred to as a VTR) is performed by connecting two VTRs. At this time, the reproducing VTR automatically determines the recording time mode of the tape, but the recording VTR must manually set the recording time.

Problems to be Solved by the Invention However, in the conventional configuration in which the recording time mode on the recording side is manually set as described above, the recorded tape is played back once, the recording time mode is confirmed, and then the recording time on the recording side is set manually. It is necessary to set the mode, and the operability is poor. Furthermore, if this operation is forgotten, the recording time mode of the recorded tape on the playback side may be different from the recording time mode setting on the recording side.

In particular, when the playback side is in the long-time mode and the recording side is in the standard mode, there is a problem that there is not enough tape on the recording side.

In view of the above problems, the present invention provides a magnetic recording/reproduction device in which the recording time mode on the recording side automatically becomes the same as the recording time mode of the recorded tape on the reproduction side without manually setting the recording time mode on the reproduction side. The purpose is to provide.

Means for Solving the Problems The magnetic recording and reproducing apparatus of the present invention is configured such that a recorded tape reproduced by the reproducing apparatus is recorded on the tape by the recording apparatus, and the reproducing apparatus is configured to record the recorded tape in the recording time mode of the recorded tape. The present invention is characterized in that the recording time mode of the recording device is adjusted to the recording open mode of the recorded tape in response to this detection signal.

Effect: With this configuration, the recording time mode on the recording side automatically becomes the same as the recording time mode of the recorded tape on the playback side, which eliminates the need to set the recording time mode on the recording side and makes it the same as the playback side. If a longer or longer tape is used on the recording side, the problem of running out of tape on the recording side can be solved.

Embodiment Hereinafter, an embodiment of the magnetic recording/reproducing apparatus of the present invention will be described with reference to the drawings. The drawing shows a block diagram of essential parts of the present invention. In the figure, P is the deck on the playback side, 18
1g and SW1 to SW3, R is the recording side deck, 2a to 2ρ and SW4. It is composed of SW7. From the playback side, 1a is a control head that reads and writes control signals.

SWl is a Pa/RFC selector switch that is provided so that recording and playback can be performed with the playback deck alone.
RFC) side, the waveform of the vertical synchronizing pulse generation circuit 1C is shaped by the waveform shaping circuit 1b, and a control signal is written by the control head 1a. During dubbing/editing, the control pulse is on the playback (PB) side, and the control pulse read by the control head 1a is amplified by the amplifier 1d, the waveform is shaped by the waveform shaping circuit 1e, and the signal is sent to the recording time mode determining section 1f. Further, the capstan FG signal obtained from the capstan frequency generator 1Q is amplified by an amplifier 1h, and waveform-shaped by a waveform shaping circuit 11.
Sent to f. The recording time mode determination unit 1f uses the control signal output from the waveform shaping circuit 1e and the waveform shaping circuit 11.
The recording time mode is determined by comparing it with the output capstan FG signal, and a recording time mode ll11tIII signal is output. SW2 is a PB/RFC changeover switch similar to SWl, and when using RFC, it can be used from the outside, and when using PB, it can be used from the outside.
The capstan motor control unit 1 receives the recording time mode control signal from the recording time mode determination unit 1f.
I am switching to send it to . The capstan motor control unit 1j detects the rotation of the capstan using the capstan FG signal output from the waveform shaping circuit 11 according to the recording time mode &iJ m 'M@, and controls the motor drive circuit 1 of 1.
Rotate the capstan motor 1g with l1IJill.
It's happening. SW3 is the SP/LP changeover switch, and SW2
This is so that the recording time mode can be manually set when the deck is on the RFC side (when the playback deck is used alone as a recorder).

The recording side decks are 1a to 2Ω, respectively.
It is the same as 1Q, and SW4 to SW6 are also the same as SW1 to SW3. However, SW4 and SW5 are on the RFC side during dubbing/editing. SW7 is dubbing Ii
This is the manual/automatic selector switch for the recording time mode on the recording deck during recording. Normally, this switch is set to automatic, but when dubbing or editing, the recording time mode control signal 1 on the playback side is used.
m is sent to the capstan motor v control section 2j on the recording side, so that the recording side also records in the same recording time mode as the reproducing side. If you want to manually set the recording time mode on the recording side, switch to the manual side. If you want to record on the recording side alone, even if switch SW7 is set to automatic,
It is necessary to be able to set the recording time mode using the changeover switch SW6. Further, during dubbing/editing, the changeover switch SW7 may be omitted if everything is matched to the recording time mode on the playback side. Selector switch SW1. SW2.
SW4. SW5 is also not necessary if the reproduction side is used only for reproduction and the recording side is used only for recording.

In this way, the recording time mode ti1m signal 1m on the playback side
By sending this to the recording deck R, the recording time mode of the recording deck R can be automatically set to the same mode as that of the reproducing deck P without having to manually set the recording time mode of the recording deck R.

Effects of the Invention As described above, the magnetic recording and reproducing apparatus of the present invention is configured so that the recorded tape reproduced by the reproducing apparatus is recorded on the tape by the recording apparatus, and the recording time mode of the recorded tape is set by the reproducing apparatus. Since the recording device's recording open mode is configured to match the recording time mode of the recorded tape in response to this detection signal, there is no need to set the recording time mode on the recording side when dubbing or editing, and playback is possible. It is possible to record in the same recording time mode as the recorded tape on the playback side without checking the recording time mode of the recorded tape on the playback side. As a result, if a tape of the same length or longer than the recorded tape on the playback side is used on the recording side, the entire content of the tape on the playback side can be recorded.
