A magnetic recording / reproducing apparatus (10A) whose recording / reproducing system is controlled by the controller (1) by being supplied, and which receives a control switching signal from the controller (1). 12A) and a second control for guiding the control signal input via a separate path to the control bus (15A) Signal input terminal (1
7A), an output terminal (16A) connected to at least a second control signal input terminal (17B) of another magnetic recording / reproducing apparatus (10B), and a control switching signal input from the controller (1). , A switching means (13A) for selectively switching the supply of the control signal to the control bus (15A) and the sending of the control signal to the output terminal (16A).

[Action]

In the magnetic recording / reproducing apparatus according to the present invention, first, the control switching signal from the controller (1) is input to the control switching signal input terminal (12A), so that the switching means (13) selectively switches. Then, it is selected whether the control signal from the controller (1) is supplied to the control bus (15A) or directly sent to the output terminal (16).

When supply to the control bus (15) is selected by the switching means (13), a control signal from the controller (1) is transmitted via the control bus (15) in the magnetic recording / reproducing apparatus (10A). It will be supplied to the recording / reproducing system. As a result, the recording / reproducing system of the magnetic recording / reproducing apparatus (10A) is controlled by the controller (1).

On the other hand, when the switching means (13) selects, for example, transmission to the output terminal (16), the control signal from the controller (1) is directly transmitted through the output terminal (16) to another magnetic recording / reproducing device ( A control signal is supplied to the recording / reproducing system via the control bus (15B) in 10B). As a result, the recording / reproducing system of the other magnetic recording / reproducing apparatus (10B) is controlled by the controller (1).

As described above, in the magnetic recording / reproducing apparatus according to the present invention, when a plurality of the magnetic recording / reproducing apparatuses (10) are installed and each magnetic recording / reproducing apparatus (10) is operated, one controller (1) is used to operate them. It is possible to control a plurality of magnetic recording / reproducing devices (10), and it is possible to significantly reduce the number of controllers (1), which was conventionally required for the number of magnetic recording / reproducing devices (10).

Therefore, when a plurality of magnetic recording / reproducing devices (10) are connected to construct one magnetic recording / reproducing system, a controller (1) for controlling the plurality of magnetic recording / reproducing devices (10) is installed. It is possible to use only one unit, the configuration of the above system is simplified, and it is advantageous in terms of cost. Moreover, since only one controller (1) is required, it is possible to operate a plurality of magnetic recording / reproducing devices (10) through one controller (1).
It is possible to improve operability.

(74) is a copy (COPY) button, (75) is a program edit (PGM EDIT) button, (76) is an edit button, (77) is a program play button, and (78) is a display section.

Next, the dubbing operation will be described. There are two possible automatic actions. First, when the preparation button (73) of the controller (1) is pressed, the A deck (10A) is in the reproduction state and the B deck (10B) is in the recording / standby state under the control of the controller (1). Next, when you press the copy button (74), the A deck (10A) will play the track at the first address of the disc (25A) and the B deck (10B).
Is the A deck (10
Record the playback signal from A). This operation is repeated until the track at the final address, for example, 50, is repeated, and when all recording is completed, it automatically switches to the stop mode, and the READY button (73)
Press again to end the operation.

Secondly, when the prepare button (73) of the controller (1) is pressed, the A deck (10A) is in the reproducing state and the B deck (10B) is in the recording / standby state under the control of the controller (1) as described above. When the lamp above the program play button (77) lights up and there is already a program play input, the program edit button (7
5) Press. Then, the A deck (10A) plays the track at the first address of the program, and the B deck (10B) records the playback signals from the A deck (10A) sequentially from the track when the program edit button (75) is pressed. To do. Then, when all recording is completed, the mode automatically changes to the stop mode and the operation is ended by pressing the preparation button (73) again.

Regarding the manual operation, the following two can be mainly considered. First, press the button (3) of the controller (1) to select the A deck (10A), and press the play button (52 ') of the controller (1) to play the A deck (10A) from any address. Put in a state. Next, the button (4) of the controller (1) is pressed to select the B deck (10B), and the dubbing input button (66 ') of the controller (1) is pressed.
Furthermore, the standby button (56 ') of the controller (1),
Then, press the record button (55 ') to put the B deck (10B) in the record state.

The second is to push the button (3) of the controller (1) to select the A deck (10A), and then press the plus / minus button (5
4 '), (53') or 10 key (70) and goats button (7
Use 1) to set the head to an arbitrary address. Next, press the button (4) of the controller (1) to push the B deck (10
Select B) and press the plus / minus buttons (54 '), (5
Use the 3 ') or 10 key (70) and goats button (71) to set the head to any address. Then, press the preparation button (73) of the controller (1). Then, the A deck (10A) is in a playback state at a preset location, and the B deck (10B) is in a recording / standby state at a preset location. Then, when the edit button (76) of the controller (1) is pressed, the B deck (10B) enters the recording state.

The following various modes are conceivable as operations that can be controlled by selecting the decks (10A) and (10B).
First, as a simple operation, if the A deck (10A) is in the playback mode and the B deck (10B) is in the playback mode, the A deck (10A) is in the recording / erasing mode and the B deck (1
0B) is also the recording / erasing mode, A deck (10A)
It is conceivable that the B deck (10B) is set to the reproduction mode while the recording / erasure mode is set to.

Also, as a program creation operation, while the A deck (10A) is set to the reproduction mode, the B deck (10B) records an image according to the program of the controller (1) or the program of the disc contained in the B deck (10B). When playing back, while the A deck (10A) is in the recording / erasing mode, the B deck (10B) records an image according to the program of the controller (1), or the B deck (10B).
It is possible to play the program of the disc in B).

It should be noted that the same can be said when the A deck (10A) and the B deck (10B) are exchanged in the above-described simple operation and program creating operation.

Further, when the A deck (10A) and the B deck (10B) are being controlled by the controller (1), the track number of the disc inserted in the A deck (10A) is the display section (78) of the controller (1). ) Is displayed below the track (TRACK) and the track number of the disc inserted in the B deck (10B) is displayed below the track sub (TRACK SUB) on the display (78) of the controller (1). To be done.
