Description

, ..1. - - ; Изобретение относитс  к приборостроению и может найти применение в накопител х на магнитной ленте (НМЛ). Известен способ многодорожечной записи и воспроизведени  кодовой информации , при котором на отдельную дорожку записывают .сигналы синхронизации и одновременно на остальные дорожки информационные сигналыс последующим одновременным воспроизведением сигналов синхронизации и информационных сигналов 1. В виду того, что дорожки в магнитной головке (МГ) при ее изготовлении смешаютс  относительно друг друга и магнитна  лента при своем движении может иметь перекос, сигналы синхронизации и информационные сигналы при воспроизведении с магнитной ленты поступают в приемное устройство не одновременно. Это снижает надежность воспроизведени  информации.;./: Наиболее близким к изобретению по технической сущности  вл етс  способ многодорожечной записи и воспроизведени  цифровой информации, при котором на одну дорожку записывают синхроимпульсы и одновременно на другие дорожки - информационные сигналы с последующим одновре-. менным воспроизведением синхроимпульсов и информационных сигналов с передачей последних в приемное устройство (2. Целью изобретени   вл етс  повышение надежности воспроизведени  информации. Достигаетс  это тем, что сигнал синхронизации после воспроизведени  формируют по заднему фронту синхроимпульса и одновременно формируют сигнал запрета на передачу информационных сигналов в приемное устройство, затем формируют по переднему фронту последующего синхроимпульса сигнал разрец1ени  и передают информационные сигналы в приемное устройство .Сущность предлагаемого способа состоит в том, что поскольку временной интервал сигнала (информационного или синхроимпульса ) в 4-5 раз больше временного смещени  сигналов относительно друг друга, можло использовать конечное врем  сигнала синхронизации, т. е. его задний фронт, по которому можно формировать сигнал информации с информационных каналов. , ..one. - -; This invention relates to instrumentation engineering and can be used in magnetic tape storage devices (NML). There is a method of multi-track recording and reproduction of code information, in which synchronization signals are recorded onto a separate track and information signals are simultaneously recorded on the other tracks with subsequent simultaneous playback of synchronization signals and information signals 1. In view of the fact that the tracks in the magnetic head (MG) during its manufacture mixed relative to each other and the magnetic tape during its movement can be skewed, synchronization signals and information signals when playing with the ma The rotary tape does not enter the receiving device at the same time. This reduces the reliability of information reproduction.; ./: The closest to the invention according to its technical essence is a method of multi-track recording and reproduction of digital information, in which sync pulses are recorded on one track and information signals simultaneously on other tracks, followed by simultaneous. Reproducing clock pulses and information signals with the latter being transmitted to a receiving device (2. The purpose of the invention is to increase the reliability of information reproduction. It is achieved by creating a synchronization signal after playback on the falling edge of the clock pulse and simultaneously generating a signal to prohibit the transmission of information signals to the receiving device , then form the resolution signal on the leading edge of the subsequent clock pulse and transmit information signals to the receiver at device. The essence of the proposed method is that since the time interval of the signal (information or sync pulse) is 4-5 times longer than the time shift of the signals relative to each other, the final time of the synchronization signal, i.e. its trailing edge, can be used to form a signal of information from information channels.
