Description

The invention relates to the field * of magnetic recording, and in particular to devices for multi-channel magnetic recording and playback.

A device for multichannel magnetic recording and playback, containing a recording path. playback on magnetic ones [1].

The known device has a relatively simple design and does not allow recording a sufficiently large amount of information.

linen, however

A device for multichannel magnetic recording and playback is also known, which contains information buses connected to a control unit connected to the inputs and outputs of the recording and reproducing paths on magnetic tapes, each of which is made with indication of the indication of recording tracks connected to the switch, a control unit and a button NEW KEY G23.

This device provides a record of a relatively large amount of information. The disadvantage of this device is the significant complexity of its maintenance.

The purpose of the invention is to reduce the complexity of the maintenance of the device for multi-channel magnetic recording and playback.

This is achieved due to the fact that a ring counter is introduced into the device for multichannel magnetic recording and reproduction, the input of which is connected to the button key, an analog switch, the inputs of which are connected to the recording and playback paths on magnetic tapes, and the outputs to the control unit, indicators of the selected paths, indicators of the number of recording tracks and indicator of parameter estimation. At the same time, the outputs of the ring counter are connected to an analog switch and to a switch connected by outputs to the indicators of 20 selected paths and to the indicators of the numbers of the recording tracks, and the indicator for evaluating the parameter is connected to the output of the control unit,

The drawing shows one of the possible variants of the proposed device for multichannel magnetic recording and playback.

The proposed device contains information bus 1 connected to the control unit 2. The control unit 2 is connected ϋ with the inputs and outputs of the recording and reproducing paths 3 on magnetic tapes 4 installed in a common tape drive mechanism '5.

Each path 3 recording-playback on magnetic tape 4 is made with _ outputs b indication of the recording tracks ⁵ connected to the switch 7, The proposed device also contains a ring counter 8, the input of which is connected to the key key '9 path selection, and an analog switch 10, input which are connected to the tracks 3 recording-play. information on magnetic tapes 4. The outputs of the ring counter 8 are connected to the switch 7, connected by 15 outputs with indicators 11 of the selected paths and with indicators 12 track numbers e-recording. The outputs of the ring counter 8 are connected, in addition, 'to the analog switch 107' 20 whose outputs are connected to the control unit 13. To the output of the control unit 13 is connected an indicator 14 for evaluating the parameter. In this case, the indicators 1 of the selected paths, the indicators 12 of the numbers of the recording tracks and the indicator 14 of the parameter estimation are made in the form of incandescent lamps.

In the proposed device, according to the signal from the button key 9, the ring counter 8 is set to the state 30 corresponding to one of the recording and reproducing paths 3 on magnetic tapes 4. The signals from the outputs of the ring counter 8 are connected to the analog switch 10 35 and to switch 7. The latter leads to the fact that the switch 7 excites one of the indicators 11 of the selected paths and one of the indicators 12 of the numbers of the recording tracks, and analog. the switch 10 acts on the control unit 13. The control unit 13 excites a parameter estimation indicator 14 if the parameter value is above normal.
