Abstract

PURPOSE:To obtain a good facility by providing the output terminal and input terminal of a track feed instructing signal, connecting the input terminal at a reproducer side and the output terminal at a recorder, side, and automatically performing the track feeding at the reproducer side as well when the track feeding at the recorder side is performed. CONSTITUTION:When the recording operation performed with the signal transmitted from a recording instruction switch 11 as a trigger is completed, a magnetic head 4 is moved to the next track automatically and a signal is made to be outputted to a track feed instructing output terminal 13. Also, when a feeding signal is fed to a feed instructing input terminal 14 at reproducing time, one track feeding is made to be executed similar to the time when a signals is fed from a track feeding switch. The dubbing of the magnetic disk being set at the reproducer side only by pushing the recording instruction switch 11 at the recorder side is thus executed and a good facility is obtd.

Description

[Detailed description of the invention] [Field of application] The present invention relates to a magnetic disc sheet-based magnetic disc sheet.
This invention relates to a system that has been devised for ease of use when dubbing is performed using multiple devices.

[Conventional technology]

There are various types of conventional recording/reproducing machines of this type that have output terminals for head feed signals;
Moreover, there is no example of generating a signal satisfying the conditions described in the claims. An example of this type of device is disclosed in Japanese Patent Application Laid-Open No. 60-242570.

[4 points to be solved by the invention] The process of creating the back side of magnetic media using two magnetic recording and reproducing machines, one as a reproducing machine and the other as a recording machine, is generally called dumping. If the recording/playback device is a disk sheet, it is necessary to send the magnetic head one track at a time, so to perform the above dubbing operation, change the track on the playback device and change the screen, then record that screen on the recorder, and then It is necessary to repeat the complicated process of sending the data to the track on the player side, and then sending it to the track on the player side.

The object of the present invention is to propose an easy-to-use dubbing system that allows this work to be performed in a simple manner.

[Means for solving problems]

In order to achieve the above purpose, an output terminal and an input terminal for the track advance instruction signal are provided, and the input terminal on the player side and the output terminal on the recorder side are connected. This is achieved by providing a control system in which track feed on the machine side is also carried out automatically, thereby reducing the complexity of the operation by half.

[Effect]

When the recording operation triggered by the signal from the recording instruction switch is completed, the magnetic head is automatically moved to the next track and a signal is output to the track advance instruction output terminal. Also, in this life, when the above-mentioned feed signal is applied to the feed instruction input terminal, one track feed is performed in the same way as when a signal is applied from the track feed switch, so that all you have to do is press the record instruction switch on the recorder side. Dubbing is performed on the d&ki disc set in the player.

[Embodiment] An embodiment of the present invention will be described below with reference to FIG. 1 showing its configuration and FIG. 2 showing a connection method during dubbing.

In FIG. 1, numeral 1 denotes a recording/signal input terminal for video signals, etc., 2 a recording circuit, 3 a recording/reproducing switch, 4 a magnetic recording/reproducing head, and 5 a reproducing circuit.

Reference numeral 6 indicates an output terminal for the reproduced signal. 7 is a disk-shaped magnetic sheet on which No. 1d is recorded, and a plurality of concentric circles 41
A B-air track is formed, and the 1M1-air playback head 4 writes and reads signals. 8 is a drive block consisting of a near motor and its control circuit, etc., which rotates the magnetic sheet at a constant speed.

A head feeding block 9 moves the magnetic reproducing head 4 to a designated track position on the magnetic sheet 7, and is composed of a drive source such as a pulse motor and its control circuit. Reference numeral 10 denotes a system control circuit that controls the entire operation of the device, and is composed of a micro-gauger, a logic IC, and the like. 11 is a recording switch, and when a recording instruction signal is sent to the system control circuit 10 by closing it for a short time, the system control circuit 10 switches the recording/reproduction changeover switch 3. A control signal is sent to the drive book 8, etc., and a signal (V) is applied to the input terminal 1 and is recorded on the track of the magnetic sheet 7 that the magnetic reproducing board 4 is in contact with at that time. When the process is completed, the system control circuit 10 sends the head feed block 9.
A one-track movement signal is sent to the magnetic head to move the magnetic head one track, and at the same timing, a 4m signal is also output to the track feed instruction output terminal 14. Reference numeral 12 denotes a playback feed switch, and when a feed instruction signal is applied to the system control circuit 10 by short-time r'ji closing, a control signal is sent from the system control circuit 1G to the head feed block 9, and the magnetic playback switch is activated. 4 moves by one track $-f'. 13 is a track feed instruction input terminal, and when a feed instruction signal is applied to this input terminal, the same output as when a signal is applied from the switch 12 is sent from the system control circuit 10 to the head block? sent to.

Figure 2 shows the magnetic ML recording/reproducing machine 2 configured with two ports as shown in Figure 1.
An example is shown in which the stands are connected so that dubbing is possible, and the parts marked with the same numbers as in FIG. 1 indicate the same functions. The device on the left side of the diagram is in playback mode, the right side is in recording mode, and if this is the connection, l@
From the functions explained in FIG. 1, it can be fully understood that dubbing on the magnetic sheet on the player side is possible by simply pressing the recording switch 11 on the recorder side.

〔Effect of the invention〕

According to the present invention, when dubbing a magnetic disk sheet, the necessary connections are made between the playback machine and the recording machine, and once the dubbing and dubbing sheets are set in both, the recording operation can only be performed on the recording machine side. Dubbing is performed, and the system is much easier to use than conventional systems.
