Description

The invention relates to instrumentation and can be used in devices designed to record information on a magnetic drum-type media. 5

According to the main author. St. No. 706877, there is known a device for recording information on a drum-type magnetic medium containing an input clip, a recording amplifier to which a magnetic recording head is connected * 0, and playback amplifiers, to the input of each of which a separate magnetic playback head is connected.

The presence of 15 signal-end indicators and a switch connected in series; * connected between the input of the recording and output amplifier ”! all playback amplifiers, as well as an adder connected between the output 20 of the switch and the input of the same recording amplifier, as well as the connection of the second input of the adder with the input terminal allows the device to be made more broad-functional. | * 1J. 25

However, the accuracy of the recorded information with current requirements for such a process is not high enough.

, The purpose of the invention is to increase the accuracy of ₃₀ {nos.ti recorded information.

This goal is achieved by the fact that a pulse generator, a magnetic erase head ^ ^35, an erase amplifier and a signal presence indicator, a time relay, a trigger and a key are connected in series to it, a pulse eraser is introduced into the device for recording information on a magnetic carrier of a drum type, and the cry is set between the output of the adder and the input of the recording amplifier, the erase amplifier is connected to the trigger output, a pulse generator is connected between the output of the signal presence indicator and a separate input of the switch, the second trigger input and it is connected to the input of the pulse generator, and the input of the signal availability indicator is connected to the input terminal.

The drawing shows a structural diagram of the proposed device ..

The input terminal 1 is connected to the recording magnetic head 2 through the adder 3, the key 4 and the recording amplifier 5 connected in series ^{. The} same terminal ⁵⁵ is connected via the signal presence indicator 6 to the pulse generator 7, trigger 8 and turnip 9 at the same time, and the trigger output 8 through an erase amplifier 10 is connected to an erase magnetic head 11. The magnetic recording heads 2, erasing 11 and playback 12 are located around the carrier 13 of the drum THnaj, while the heads 12 are connected through the respective playback amplifiers 14 to the switch 15, to which the signal end indicator 16 is also connected.

When a signal to be recorded arrives at the input terminal, this signal, for example, a radio pulse, overturns trigger 8 and starts the time relay 9 with generator 7. The key is opened and the input signal is recorded on carrier 13. After the signal ends, pointer 16 is activated and the pulse is sent to a commutator, but at the same time an impulse comes from the generator 7, which causes the carrier ^ to rotate by the required angle, which is determined by the number of playback heads and their location around the carrier circumference relative to tionary head 2 records. That is, the pulse from the pointer 16 causes the switch to create an output signal reproduced by the head 12 to which the previously recorded signal came last. After a time equal to one revolution of the medium, the time relay is activated and its impulse again overturns the trigger, thereby stopping the recording process. Recording of the incoming information similarly takes place: the input signal is recorded on the medium, and the rest of its track is filled with the signal reproduced by the corresponding head 12. In this case, signals are sent to the output bus 17, which cyclically repeat the input signal.

When using the invention, the standard deviation of the frequency of the output signal from the frequency of the input decreases by more than an order of magnitude, which in some cases eliminates duplication and, in turn, makes the device itself less energy-intensive.
