BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording and reproducing apparatus having a rotary head type audio recording function.

0002

2. Description of the Related Art In a conventional magnetic recording and reproducing apparatus having a high-fidelity audio recording function, as shown in FIG. Although it has a recording and reproducing circuit 21, switching between recording and reproducing modes of these two audio recording methods is controlled by a common recording and reproducing switching signal 9.

0003

[Problem to be Solved by the Invention] In such conventional technology, since the recording and playback switching control signals for the rotary head system and the fixed head system are common, the two-channel audio reproduction signal obtained from the rotary head It has been impossible to record a mixed signal of this and an external audio signal using an audio recording circuit with a fixed head.

The present invention solves the above problems and, in addition to conventional applications, adds an external audio signal to a high-fidelity audio signal reproduced from a rotating head, and reproduces the sound on a longitudinal audio track using a fixed head. The purpose of the present invention is to provide a magnetic recording/reproducing device capable of recording data on a magnetic field.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a rotating head-based signal processing means, a fixed head-based signal processing means, and a first sound reproduced by the rotating head-based signal processing means. A first mode in which a third signal generating means for mixing the signal and a second external audio signal to obtain a third audio signal, and a rotary head system and a fixed head system signal processing means are both in a recording or reproducing state. (normal mode) to the first
A mode switching means is provided for switching to a second mode (special mode) in which only the fixed head signal processing means records a third audio signal in the reproduction state of the mode.

[0006]

[Operation] With the above-described configuration, the present invention controls recording and playback using a common control signal for both the rotary head and the fixed head in the normal mode, and in the special mode, that is, the reproduced audio signal from the rotary head and the external audio signal. Only when it is necessary to mix and record with a fixed head, the recording/reproducing circuit using a rotating head uses the conventional switching signal, and the recording/reproducing circuit using a fixed head is forced to the recording system and the mixed signal is fixed. Record by head.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a magnetic recording/reproducing apparatus according to an embodiment of the present invention. Here, a recording/reproducing fixed head 1, a fixed head reproducing amplifier 2, a recording/reproducing switch 3,
A circuit equipped with a recording amplifier 4 is an audio recording/reproducing circuit using a fixed head, and a rotating recording/reproducing head (1) 11, (2) 1
2. The circuit provided with the rotary head recording/reproducing signal processing circuit 13 is an audio recording/reproducing circuit using the rotary head. Also,
Of the three switches in the figure, number 3 is a fixed head recording/reproducing switch, which is switched to the A side during recording and to the B side during playback. In addition, 5 is a fixed head circuit recording signal changeover switch, which is set to D in normal mode and C in special mode.
Switch to the side. Further, 17 is a normal/special mode changeover switch, which is connected to F in the special mode and to E in the normal mode. A recording mode signal 18 is connected to the F side of the switch 17, which is a control signal for putting the fixed head recording/reproducing circuit into a recording state.

In normal mode operation, the fixed head system and the rotary head system recording/reproducing circuit perform the same operation. That is, the changeover switch 17 supplies the recording/reproduction switching signal 9 to the rotary head recording/reproduction signal processing circuit 13 and also to the recording/reproduction switch 3 for the fixed head system. Therefore, both the rotating head system and the fixed head system operate in the same mode.

On the other hand, in the special mode, switch 1
7 is switched to the F side, the recording/reproducing switch 3 is brought into contact with the A side, and the fixed head system enters the recording mode regardless of the recording/reproducing switching signal 9. In this case, when the switching signal 9 is in the reproducing state, the rotary head system is in the reproducing state, and the fixed head system is in the recording state. At this time, the rotating head system signal processing circuit 1
The signals 19 and 20 reproduced at 3 are mixed with the external signal 10 that has passed through the amplifier 15 in the recording signal mixer 16, and are then amplified by the recording amplifier 4 via the fixed head circuit recording signal changeover switch 5 and then fixed to the fixed head circuit for recording and reproduction. It is supplied to the head 1.

As described above, according to the magnetic recording/reproducing apparatus of the embodiment of the present invention, the rotary head system signal processing circuit and the fixed head system signal processing circuit are each independently controlled, and the reproduction output of the rotary head system and the external signal are controlled independently. The sound is arranged so that it can be recorded on a fixed head by mixing it with other signals (your voice, music, etc.) with the high-fidelity rotating head and recording it on a fixed track. Can be recorded.

[Effects of the Invention] As is clear from the above embodiments, according to the present invention, while playing back video and high-fidelity audio (accompaniment), you can mix and record your own singing with high-fidelity audio (accompaniment) using a microphone. It is possible to provide a magnetic recording and reproducing device that allows users to enjoy a video karaoke function and also to be used as an LL system for language practice.
