Description

I

The invention relates to accumulated information, namely, devices for multi-track magnetic recording and information playback.

A flexing device for multi-track magnetic recording and reproducing information containing recording and reproducing units, a control unit and tape drive mechanism and operating mode switch connected to its outputs. The known device has a relatively simple design, but does not ensure the continuity of the multi-track magnetic recording and reproducing information. .

It is also known a device for multi-track magnetic recording and reproducing information, containing recording and reproducing apparatuses, each of which consists of a recording unit and a reproducing unit, the input and output of which are connected to a recorder of recorded and reproduced information.

from the control unit and from the operation modes connected to its outputs of the switchboard, the memory unit, the tape mechanism, the tape meter footage counter, and the first, second, and third emf. I. This device allows to ensure the continuity of the multi-track magnetic. recording and playback 2.

The disadvantage of this device is the considerable complexity of its maintenance.

The purpose of the invention is to simplify the service of a device for multi-track magnetic recording and reproduction of information.

Claims (2)

The goal is achieved due to the fact that a descriptive command and a fourth AND element, the outputs of which are connected to a control unit connected to the output of the first And element of another recording and playback apparatus, are inserted into each recording and playback apparatus, an additional memory unit connected to the output the second element And one of the inputs of the imager of the recorded and reproduced information, and the backing line, and, in each recording and reproducing device, a delay line and a memory block are connected between the inputs And element and the outputs of the command decoder, connected to the outputs of the tape meter of the tape, to the input of the first element And, to the input of the second element And, the output of which is connected to an additional memory block of another recording and playback device, and to the input of the third element And, the output of which is connected to a switch of operating modes, connected by outputs to a control unit of a remote recording and playback apparatus. The drawing schematically shows the proposed device option. The device contains recording and reproduction apparatus I, each of which consists of a recording unit 2 and a playback unit 3, the input and output of which are connected to the recorder 4 of recorded and reproduced information. Each recording and reproducing I device also consists of a control unit 5 and 6 operating modes connected to its outputs, a memory unit 7, a tape recorder 8, a tape meter counter 9 and the first, second and third elements 10 12. ..1 Each recording and replaying I device contains a decoder for 13 commands and a quarter 1 AND 14 element, the outputs of which are connected, to the control unit 5, an additional memory block 15 connected to the output of the second AND II element and one of the inputs of the imager 4 recorded and reproduced information, and a delay line 16. In this case, the control unit 5 is connected to the output of the first AND element of another recording and reproduction apparatus 1. In each recording and reproducing apparatus 1, delay 16 and memory block 7 are connected between the inputs of the fourth element 14 and the outputs of the decoder 13 commands. The decoder 13 commands connected to the outputs of the counter 9 footage of the magnetic tape, to the input of the first element And 1O, to the input of the second element And 11 and to the input of the third element And 12, Bi-lhod which is connected to the switch in the operating modes, connect. P), with inputs to control unit 5 294 of another recording and reproduction apparatus I. In this case, the output of the second element I I I connection with the additional block 15 of the memory of another recording and reproduction apparatus 1. Tape mechanism, g 8, operate in the modes of working stroke, fast forward, rewind and stop, the inclusion of which is provided by supplying the appropriate commands from the control blocks 5. In this case, the decoder 13 commands, depending on the reserve of the magnetic tape on the tape drivers, 8, generates the signals necessary for the joint operation of the two recording and reproduction apparatus I. The use of the invention greatly simplifies the maintenance of the device for multi-track magnetic recording and information playback. Claims An apparatus for multi-track magnetic recording and reproducing information comprising recording and reproducing apparatuses each. of which consists of a recording unit and a playback unit, the input and output of which are connected to the recorder of recorded and reproduced information, from the control unit and from the operating mode switch connected to its output, a memory unit, a tape mechanism, a tape meter and the first one, the second and third elements are And, in contrast to the fact that, in order to simplify the maintenance of the device, a command aeumlipator and a fourth And element are entered into each recording and playback apparatus, and their outputs are connected to a control unit connected to the output of the first And other element of the recording and playback apparatus, an additional memory block connected to the output of the second And element and one of the shaper inputs of the recorded and reproduced information, and a delay line, each delay recording and reproducing unit and a delay LINE and a memory unit is connected between the inputs of the fourth And element and the outputs of the command decoder connected to the outputs of the tape meter footage}, 1, to the input of the first And element, to the input of the second element And, the output of which is connected to an additional memory block of another device.
