Изобретение относитс к измерительной технике, а именно к способам измерени перекоса движущегос магнитного носител с применением электрических и магнитных методов .The invention relates to a measurement technique, in particular, to methods for measuring the bias of a moving magnetic carrier using electrical and magnetic methods.
Известен способ измерени колебаний скорости по ширине двил ущегос в лентопрот жном механизме носител , включающий запись измерительных сигналов на параллельных дорожках носител , воспроизведение сигналов , устранение паразитной амплитудной модул ции, получение напр жени , пропорционального отклонению частоты воспроизводимого с каждой параллельной дорожки сигпала от среднего значени , и последующее получение разности этих напр жепий.A known method for measuring speed fluctuations across the width of two legs in a tape drive mechanism includes recording measurement signals on parallel tracks of a carrier, reproducing signals, eliminating parasitic amplitude modulation, obtaining a voltage proportional to the deviation of the frequency reproduced from each parallel track of the sigpal from the average value and the subsequent obtaining of the difference of these pressures.
Цель изобретени - повышение точности измерени перекоса носител .The purpose of the invention is to improve the accuracy of measurement of carrier skew.
Это достигаетс тем, что полученную разность напр жений интегрируют.This is achieved by integrating the resulting voltage difference.
На чертеже показана блок-схема устройства дл реализации предлагаемого способа.The drawing shows a block diagram of the device for implementing the proposed method.
Измерительный сигнал, занисанный на параллельных дорожках носител , воспроизводитс блоком 1 магнитных головок и после усилени в блоках 2 и устранени паразитной амплитудной модул ции в блоках 3 поступает на измерители 4 и 5 отклонени частоты измерительных сигналов от среднего значени . С выходов измерителей напр жение, пропорциональное отклонению частоты измерительного сигнала в каждом канале от среднего значени , подаетс в блок 6, где вычисл етс разность папр жений измерителей. Разностное напр жение поступает в блок 7 интегрировани .The measuring signal underestimated on the parallel tracks of the carrier is reproduced by the block 1 of the magnetic heads and, after amplifying in blocks 2 and eliminating parasitic amplitude modulation in blocks 3, is fed to the meters 4 and 5 of the frequency of the measuring signals from the average value. From the outputs of the meters, a voltage proportional to the deviation of the frequency of the measuring signal in each channel from the average value is fed to block 6, where the difference in meter gains is calculated. The differential voltage enters the integration block 7.
Интегрирование разности позвол ет исключить р д ошибок и тем самым повысить точность измерени перекоса.Integrating the difference eliminates a number of errors and thereby improves the accuracy of the skew measurement.
