Изобретение относитс к области нрнборостроенн I может быть нспользовано при нсслсдованнн лентопрот жных механпз.мов аппаратов магнитной записи.The invention relates to the field of artificial boring, and can be used in connection with tape recorders of magnetic recording apparatus.
Известные устройства дл исс тсдовани влн нп перпендикул рных колебаний магнитной ленты на точность записи-воспроизведенп электрических сигналов, содержащие блоки воспроизведени , коррел тор, магнитную головку, выполненную с несколькимп воздушп 11мп каналами, соединенными с обидим компрессором, недостаточно точны.The known devices for investigating the perpendicular vibrations of a magnetic tape on the accuracy of recording-reproduced electrical signals containing playback units, a correlator, a magnetic head made with several air ducts connected to an offended compressor are not accurate enough.
Дл повышени точпости результатов псследоваппй предлагаемое устройство снабжено датчиком давлени и соединенным с ним последовательно функциональным блоком, включенными между точкой соединени дроссел с воздушным каналом магнитной головки и вторым входом иснользуе.мого в схеме коррел тора, блок воспроизведени которого подключен к обмотке этой же магнитной головки .To improve the results of the results, the proposed device is equipped with a pressure sensor and a function block connected in series with it connected between the point of connection of the throttle with the air channel of the magnetic head and the second input of the correlator whose playback unit is connected to the winding of the same magnetic head.
На чертеже приведена схема описываемого устройства.The drawing shows a diagram of the described device.
Магнитна лента / перемещаетс мимо магнитной головки 2, выполненной с воздушным каналом 3. Обмотка головки через блок воспроизведени 4 подключена к одному из входов коррел тора 5, воздушный канал головки через датчик давлен1 6 и функциональный блок 7 подключен к другому входу коррел тора. Воздушный канал магнитной головки св зан также через дроссель 8 и блок реверсировани 9 с компрессором 10.The magnetic tape / moves past the magnetic head 2 made with the air channel 3. The head winding through the playback unit 4 is connected to one of the inputs of the correlator 5, the air channel of the head through the pressure sensor 6 and the functional unit 7 is connected to the other input of the correlator. The air channel of the magnetic head is also connected via the choke 8 and the reversing unit 9 to the compressor 10.
Если в ; звестных устройствах перпендикул рные колебани магнитной ленты нос т случайный характер и их систематичность практически невозможно учесть, то в предложенном устройстве можно искусственно вводить предыскажени . Зна их величину и направление , можно с достаточной степенью точности проводить исследовани , анализ и измерени как отдельных перпендикул рных колебаний магнитной ленты, так и совокупность ее колебаний.If in ; known devices perpendicular vibrations of the magnetic tape are random in nature and their systematicity is almost impossible to take into account, then in the proposed device it is possible to artificially introduce pre-emphasis. Knowing their magnitude and direction, it is possible with a sufficient degree of accuracy to conduct research, analysis and measurements of both individual perpendicular vibrations of a magnetic tape, and the totality of its vibrations.
