Description

- - ;;: -,., l LU. ., v: .i

The invention relates to the accumulation of fformalacin and, in turn, to devices for controlling the MariiBt multislot tract of the Zane-Vos pO1 chain.

It is known a device for controlling the cable channel of the magnetic aaimcpvrs ronzvedevn, which contains a power unit, is known | 1and connected to the inner lj. The device is known to have a relative; but simple construction.

The disadvantage of the known device is the fact that the error of the result of the control of the internal magnetic channel of the magnetic recording system is repeated.

It is also known a device for ksdatro-, l of a multichannel magnetic ea "recording-reproduction path", which contains the input needle of the start mode, connected to the first trigger, the output of which is connected to the test switchboard. fishing, connected to the inputs of the recording unit, the delay line connected to the input of the second trigger, the output of which is connected to the logical element And, under

connected to the input of the counter, and block. playback 2. This device provides relatively high accuracy of the result of monitoring the multichannel path of the magnetic recording-recording.

The drawback of the device is the considerable complexity of the process control of the multichannel magnetic recording path-, reproducing ..

The purpose of the invention is to control the process of controlling the multi-canal tract by the magnetic one. Record-play.

Claims (2)

This is due to the fact that a pulse driver connected between the output of the first trigger and the input of the delay line OR logical element connected between the outputs of the playback unit and the logical element AND, the decoder, the input KOToporq is connected to the device for controlling the multi-channel magnetic recording-reproduction path. to the counter, and the output - to the first and second triggers, additional 781968 meters, connected to the input bus of the start-up mode, additional logic gates And, connected to the output of the second th flip-flop, and inverters, the inputs Drpopnitelnyh counters soy dineny with additional logical elomentami And 6dna part kot6 | ryh pBdsoed not to block exits vosprbizbepeni directly, and the other - through inverters. Hia's drawing shows one of the possibilities of the proposed device for an integrated multi-channel channel of the Nagyit recording-reproducing circuit. The device contains an input show 1 of the start mode, connected to the trigger 2, the output of KttTopWO is connected to a switch 3 test signals, which are connected to 4 watches; ; ye y y | fdvannym with your schoolchip exposure to magnetic recording media 5. The output of the first trigger 2 is connected through the driver to the input of the line 7 delay. A second delay line 7 is connected to the input of the second trigger 8, the output of which is a logic element And 9, The output of a logic element And & poik ychey to the input of the counter 10 connected to the input bus BUS mode 1 start. The id counter is connected to the input of the decoder 11, the output of which is connected to and second triggers 2 and 8. Device; it contains a taiga oriental OR 12, connected between the 13 playback and logical terminals and 9. In this case, the playback unit 6 Shontnrova with 1m 3} 3 &} co-operation with the magnetic field of the cipher set 5, additional counters 14, connected to the input bus of the start mode 1, additional logic elements I 15 connected to the trigger output of the trigger 87 and with the Kc of the trigger circuit 15, connected to the output of the trigger 87 and with the KChkda trigger bus, and 15 connected to the output of the trigger trigger 87. The counter 14 is connected to the AO of the Gymic elements of I 1E, one part of which is connected to the outputs of the Id block of the direct playback), and the other is through inverters 16, co-linear with L (OR 12). The device also includes between the output 1 mv of the switch of the signal source 3 and the otcoM record 4, the impulse received via the code bus 1 of the start mode clears the readings of the counter 10 and additional (coders 14, and also sets the first trigger 2 to switches the test signals 3. In this case, the pulse formed by the pulse shaper 6, after a delay in the delay line 7, sets the second trigger 8 to the state that ensures opening the AND 9 logic element and the additional AND 15 logic elements. which are counted by the Yun counter, is used for the reliability of data logs. From the readings of counter 10, as well as additional counters 14, one can judge not only the reliability of magnetic recording-reproduction, but also the number of piping pulses and traps when playing false pulses. The use of the invention makes it possible to significantly simplify the sagging of the monitoring of the multichannel magnetic recording-reproduction path. Claims. A device for controlling the multiplex Hoixi magnetic recording-reproduction path, which contains an input bus of start mode connected to the first trigger, the output of which is connected to the test switch s, connected to the inputs of the recording unit, a delay line connected to the input of the second tjSjHTepa, the output of which is connected to the logical element And connected to the input of the counter, and the unit rec | Ozvedvenv, characterized in that, with the control of the control process, it introduced the impuser connected between the output of the first trg and the logical input element OR, the logical element OR, I and I, the decoder, the input of which is connected to the counter, and the output to the first and second triggers, additionally counters connected to the input bus of the start mode, are additional I logic elements connected to the output of the second trigger, and inverters inputs For more counters coupled to additional elements logicheskimn And, one part of which is connected to the outputs of the reproducing unit directly, and the other - Th Res inverters.
