Description
Известны устройства поперечной строчной магнитной записи, в которых процесс записи и последующее за ним воспроизведение производитс вращающимс диском с магнитными головками дл переприема телеграмм.Transverse horizontal magnetic recording devices are known in which the recording process and the subsequent reproduction are performed by a rotating disk with magnetic heads to re-receive telegrams.
Описываемое устройство обеспечивает получение высокого переходного затухани .The described device provides high transient attenuation.
Это достигаетс тем, что в описываемом устройстве примен етс электронный коммутатор.This is achieved by using an electronic switch in the device described.
Коммутатор включен между усилителем записи и усилителем воспроизведени и попеременно подключает воспроизвод щий и записывающий каналы к соответствующим головкам. Поэтому воспроизведение производитс в течение коротких отрезков времени, а в промежутках между ними осуществл етс запись.A switch is connected between the recording amplifier and the playback amplifier, and alternately connects the recording and recording channels to the respective heads. Therefore, playback is performed for short periods of time, and in the intervals between them is recorded.
На чертеже приведена блок-схема предлагаемого устройства.The drawing shows a block diagram of the proposed device.
Записывающий сигнал 1 попадает в головку записи 2 только при наличии положительного управл ющего импульса от электронного коммутатора 3 на входе управл емого усилител записи 4. В это врем усилитель воспроизведени 5 выключен запирающим устройствбм 6, на которое воздействует импульс от электронного коммутатора 5. После прекращени действи импульса на входе усилител записи 4 последний запираетс , а усилитель воспроизведени -5 подключаетс к воспроизвод щей головке.The recording signal 1 enters the recording head 2 only if there is a positive control pulse from the electronic switch 3 at the input of the controlled recording amplifier 4. At this time, the playback amplifier 5 is turned off by the locking device 6, which is affected by the pulse from the electronic switch 5. the pulse at the input of recording amplifier 4 is locked, and the playback amplifier -5 is connected to the playback head.
Таким образом, усилитель записи 4 и усилитель воспроизведени 5 включаютс попеременно, чем обеспечиваетс высокое переходное затухание между каналами записи и воспроизведени .Thus, the recording amplifier 4 and the playback amplifier 5 are switched on alternately, which ensures a high crosstalk between the recording and playback channels.
Однако частотный, диапазон описанного устройства сравнительно ограничен и зависит от частоты коммутирующих импульсов.However, the frequency, range of the described device is relatively limited and depends on the frequency of the switching pulses.
Предмет изобретени Subject invention
Устройство поперечной строчной магнитной записи и воспроизведени одним .вращающимс диском с магнитными головками, преимущественно дл .переприема фототелеграмм, о.тл и ч а ю щеес тем, что, с целью повьгщени переходного затухани , между записывающей и воспроизвод щей головками при одновременном процессе записи и воспроизведени в нем, между усилителем записи и усилителем воспроизведени включен коммутатор, попеременно подключающий воспроизвод щий и записывающий каналы.A transverse horizontal magnetic recording and reproducing device with a single rotating disk with magnetic heads, mainly for transcending phototelegrams, ots and hrs, which, in order to increase the transient attenuation, between recording and reproducing heads during simultaneous recording and recording playback in it, between the recording amplifier and the playback amplifier, a switch is switched on, alternately connecting playback and recording channels.
