Description

The invention relates to instrumentation, and in particular to devices for ⁴ magnetic recordings, which can be used to rewrite programs in a selected period of time.

A device for magnetic recording is known, which is made with an elongated drive shaft and with elongated axes of the podkatushnikov, which allows you to simultaneously conduct two magnetic tapes [ΐ} and С2] in the path of the magnetic recording apparatus.

The disadvantage of this device is the relatively high spurious oscillations of the magnetic tape, the most remote from the base of the mechanism, which leads to distortion of the recorded and reproduced information. An attempt to untie the movement paths of a few 20 improves the output parameters of the recorded and reproduced information, but does not allow at the same time one of the paths to work in standby mode:

both magnetic tapes either stand or move.

Closest to the invention is a magnetic recording device comprising a magnetic drum, an input terminal, an amplifier and a head for recording information from a magnetic drum, an amplifier and a head for reproducing information from a magnetic drum, a tape drive with an electronic control circuit having Stop and Start inputs ” as well as an amplifier and recording head of information on the SzK magnetic tape.

This device allows you to record information of any short duration, but there is an increased consumption of magnetic tape.

The aim of the invention is to reduce the consumption of magnetic tape.

This goal is achieved by the fact that in the device for magnetic recording, co3 960931 holding a magnetic drum, serially connected input clamp, amplifier and recording head information on a magnetic drum, amplifier and playback head, with magnetic s drum, tape drive mechanism with an electronic control circuit having entrances Stop and.

When a signal to be recorded arrives, block 3, _{50 is} triggered; a pulse arises at its output, which, through input 15, enters circuit 12, triggers a tape drive and a time relay. The latter at the output will generate a voltage that will be delayed relative to the input pulse for the time necessary to accelerate the magnetic tape.

At the same time, i.e. the lifetime of the voltage at the output of the relay 9 turns out to be open and the key 8, which allows the signal recorded on the magnetic drum to be played back by head 6 and through the amplifier 7 and key 8 to the recording amplifier 10, head 11 and then to magnetic tape 16. As soon as the relay closes , the shaper 14 will work and its impulse (s) will stop the tape drive mechanism. When the next signal arrives, the process repeats.

Saving the amount of expendable media, namely magnetic tape, reducing the operating time of the tape mechanism can also reduce energy consumption.

A magnetic recording device is known that is made with an elongated drive shaft and with elongated axles of sub-bobbins, which allows simultaneously The path of the magnetic recording apparatus is two magnetic tapes t ll and c2. The disadvantage of such a device is the relatively high parasitic oscillations of the magnetic tape furthest from the base of the mechanism, which leads to a distortion of the recorded and reproducible information. An attempt to distribute the motion paths somewhat improves the output parameters of the recorded and reproducible information, but at the same time does not allow one of the paths to operate in the standby mode: both magnetic tapes are either standing or moving. ; Closest to the invention is a magnetic recording device comprising a magnetic drum, an input terminal, an amplifier and an information recording head on a magnetic drum, an amplifier and a voice information reproduction from a magnetic drum connected in series, a tape drive mechanism with an electronic control circuit having inputs Stop and A start, as well as an amplifier and a head for recording information on a Cz magnetic tape.
