Изобретение огносигс к автоматике и измерительной технике, а именно к способам измерени параметров движени носителей информации электростатической записи, и может быть использовано дл контрол качества функционировани прецизионных узлов развертки носител .The invention of fire detection in automation and measurement technology, in particular, in methods for measuring the motion parameters of electrostatic recording media, can be used to control the quality of the performance of precision media scan nodes.
Известны различные способы измерени неравномерности скорости движени ленточного носител , на которых основана работа устройств. Сущность этих способов заключаетс в записи на носитель импульсного тестового сигнала, воспроизведени его, вычитании из воспроизведенного опорного сигнала, по результату которого суд т о неравномерности скорости р.. 2 и СзЗ .Various methods are known for measuring the uneven speed of movement of the tape carrier on which the operation of the devices is based. The essence of these methods consists in recording a pulsed test signal on a carrier, reproducing it, subtracting from a reproduced reference signal, the result of which determines the unevenness of the speed p. 2 and C3.
Недостаток данных способов заключаетс в том, что на точность измерени вли ет деформаци носител в эаае головки воспроизведенн ,Наиболее близким по технической сущности к предлагаемому вл етс способ, основанный на записи на носитель тесгового сигнала, считывании и преобразовании его в электрический контрольный сигнал . В этом способе осуществл ют запись на носитель тестового гармсжическо- го сигнала, считывают (воспроизвод т) его, преобразуют фазу воспроизведенного сигнала и определ ют разность фаз воспроизведенного и опорного сигналов, по которой суд т о неравномерности скорости движени носител 4.The disadvantage of these methods is that the accuracy of the measurement is influenced by the deformation of the carrier in reproduction of the head. The closest in technical essence to the present invention is a method based on recording the test signal on the carrier, reading it and converting it into an electrical control signal. In this method, a test of a test signal is recorded on the carrier, it is read (reproduced), the phase of the reproduced signal is converted, and the phase difference between the reproduced and reference signals is determined, which determines the uneven speed of the carrier 4.
Недостатком известного способа вл етс то, что на точность измерени вли ют колебани продольного нат жени (деформаци носител ) в зоне щелей магнитной головки, а также имеющий место перекос носител .The disadvantage of the known method is that the accuracy of the measurement is influenced by fluctuations of the longitudinal tension (deformation of the carrier) in the region of the slits of the magnetic head, as well as the misalignment of the carrier.
Цель наобретени - повыиюнне точности измерени .The purpose of the acquisition is to improve measurement accuracy.
