Description
Изобретение относитс к измерительной технике, а именно к способам измерени поперечных колебаний носител информации электростатической записи , может быть использовано дл определени колебаний ленты-носител в виброизмерительных лаборатори х и научно-исследовательских институтах.The invention relates to a measurement technique, in particular, to methods for measuring transverse oscillations of an information carrier of an electrostatic recording, which can be used to determine oscillations of a carrier tape in vibration measuring laboratories and research institutes.
Известны способы измерени колебаний носител информации, основанные на том, что на магнитную ленту записывают контрольный сигнал и по степени его искажени суд т о колебани х магнитной ленты 1 ,.Methods are known for measuring the oscillations of the information carrier, based on the fact that a control signal is recorded on a magnetic tape and judging by the degree of its distortion it is judged about the oscillations of magnetic tape 1,.
Однако при измерении перпендикул рных колебаний этим способом результаты измерений содержат погрешность .However, when measuring perpendicular oscillations in this way, the measurement results contain an error.
Наиболее близок к предлагаемому способ, заключгиощийс в т( л, что при помощи одной «агнитной головки, котора касаетс .ча:сти дорожки записи, воспроизвод т сигнал, промодулированный по амплитуде поперечными и перпендикул рными колебани ми ленты от головки , при помощи другой головки воспроизвод т сигнал, промодулированный по амплитуде только перпендикул рными колебани ми ленты от головки.Closest to the proposed method, consisting in t (l, which, with the help of a single ferment head, which touches the recording track, reproduces the signal modulated in amplitude by transverse and perpendicular vibrations of the tape from the head, with the help of another head reproduces the signal modulated in amplitude only by perpendicular vibrations of the tape from the head.
Воспроизведенные сигналы усиливают и вычитают один из другого з.The reproduced signals amplify and subtract one from the other.
При измерении колебаний.этим способом необходимы две операции - запись и воспроизведение, что вносит дополнительные погрешности при измерении .When measuring vibrations. In this way, two operations are necessary - recording and reproduction, which introduces additional errors in the measurement.
Цель изобретени - упрощение и повышение точности измерени колебаний .ленточного носител - достигаетс тем что кошсодьный..сигнал записывают на электростатический носитель посредством электроннолучевой трубки с металловолокнистым экраном открытым лучом при посто нном напр жении на катоде, а величину колебаний определ ют по изменению величины тока пробо воздушного промежутка между экраном и носителем.The purpose of the invention is to simplify and improve the accuracy of measuring oscillations of a tape carrier — that is achieved by recording a cathode signal onto an electrostatic carrier by means of an open beam metal fiber screen tube at a cathode constant voltage, and the oscillation magnitude is determined by the change in sample current air gap between the screen and the carrier.
