Изобретение относитс к области приборостроени и может использоватьс при исследовани х лентопрот жных механизмов.The invention relates to the field of instrumentation and can be used in studies of tape mechanisms.
Известные способы измерени колебаний скорости магнитного носител путем записи периодического сигнала на измерительную сигналограмму с последующим ее воспроизведением и анализом воспроизведенного сигнала не позвол ют измер ть колебани скорости с частотами, соизмеримыми с частотой записанного сигнала.The known methods for measuring the velocity fluctuations of a magnetic carrier by recording a periodic signal on a measuring waveform with its subsequent reproduction and analysis of the reproduced signal do not allow measuring the velocity oscillations with frequencies comparable to the frequency of the recorded signal.
Цель изобретени - расширить диапазон измерений колебаний скорости в сторону высоких частот.The purpose of the invention is to expand the range of measurements of velocity fluctuations towards high frequencies.
Цель достигаетс тем, что на измерительную сигналограмму записывают сигнал пилообразной формы и по отношению посто нной составл ющей к переменной воспроизведенного сигнала суд т о колебани х скорости магнитного носител .The goal is achieved by recording a sawtooth-shaped signal onto the measuring waveform and judging the constant component of the reproduced signal variable to judge the speed fluctuations of the magnetic carrier.
Описываемый способ по сн етс чертежом.The described method is illustrated in the drawing.
Измерительную сигналограмму 1 с остаточным магнитным потоком пилообразной формы воспроизвод т на исследуемом аппарате магнитной записи индукционной головкой 2. На зажимах головки 2 получают напр л ение, мгновенное значение которого пропорционально мгновенной скорости магнитного носител . Полученное напр жение усиливают в усилителе 3 и подают на осциллограф 4, где измер ют переменную и посто нную составл ющие нанр жени , и по их отношению суд т о величине коэффициента неравномерности скорости движени магнитного носител .The measurement waveform 1 with residual flux of a sawtooth shape is reproduced on the magnetic recording apparatus under investigation by an induction head 2. At the head clamps 2 a voltage is obtained, the instantaneous value of which is proportional to the instantaneous speed of the magnetic carrier. The voltage obtained is amplified in the amplifier 3 and fed to the oscilloscope 4, where the variable and constant components of the voltage are measured, and by their ratio the value of the coefficient of uneven speed of movement of the magnetic carrier is judged.
