Изобретение относитс к области приборостроени , а именно к магнитной записи.The invention relates to the field of instrumentation, namely magnetic recording.
Известны способы контрол синхронности транспортировани сигналоносителей, основанные на оценке качества изображени при печати или перезаписи материала, на измерении детонаций полученных сигналограмм, методом Лауфера и т. д.Methods are known for controlling the synchronization of the transport of signal carriers, based on an assessment of the quality of the image when printing or rewriting material, measuring the detonations of the received waveforms, using the Laufer method, etc.

Это отношение может быть заменено разностью величин, соответствующих отклонению сравниваемых величин от единицы: ZVVIn order to increase the operability of the measurements and to realize the possibility of estimating the resulting transport error of the waveforms, a method by which a conclusion is obtained based on a mathematical approximation for calculating the ratio of values slightly different from one is obtained. This ratio can be replaced by the difference of the values corresponding to the deviation of the compared values from the unit: ZVV
Z,-переменна составл юща отношени скоростей.Z, is the variable velocity component.
Сущность способа контрол синхронности транспортировани сигналоносителей состоит в воспроизведении сигнала с двух контрольных сигналограмм, последующем преобразовании сигнала, например частотном детектировании , при котором определ ютс текущие значени переменных составл ющих скоростей транспортировани , и сравнении мгновенных значений переменной составл ющей скоростей двух сигналоносителей. Таким образом, сравниваютс мгновенные значени скоростей сигналоносителей, определенные соответствующими электронными методами.The essence of the method of controlling the synchronization of transportation of signal carriers is to reproduce the signal from two control signals, subsequent signal conversion, such as frequency detection, which determines the current values of the variable components of the transport speeds, and compares the instantaneous values of the variable component of the speeds of the two signal carriers. Thus, the instantaneous values of the velocities of the carriers determined by the corresponding electronic methods are compared.
Предмет изобретени р ют, как разность относительных колебаний их мгновенных скоростей, а последующую обработку сигналов воспроизведени осуществл ют на заключительном этапе.The subject matter of the invention is the difference in relative fluctuations of their instantaneous speeds, and the subsequent processing of the playback signals is carried out at the final stage.
