Description

ней стенки корпуса 1, обеспечива  тем самым возможность контрол  нат жени  пассика в процессе эксплуатации и, периодического контрол  в процессе хранени  кассеты без ее вскрыти .the walls of the housing 1 therewith, thereby ensuring the possibility of controlling the tension of the belt during operation and periodically monitoring during storage of the cartridge without opening it.

Контроль за нат жением пассика может быть осуществлен путем взаимодействи  динамометра или измерител  нат жени  магнитной ленты с пассиком 6.The tension control of the belt can be carried out by the interaction of a dynamometer or a tension meter of the magnetic tape with the belt 6.

Обеспечение контрол  за нат жением пассика позвол ет предотвратить использование кассеты, коэффициент упругости пассика которой выходит за пределы допустимых величин, что позвол ет , в конечном счете, повысить достоверность записиФормула изобретени Providing control over the tension of the belt makes it possible to prevent the use of a cassette, the elastic coefficient of which has gone beyond the limits of permissible values, which ultimately improves the reliability of the recording.

Двухшпулька  рулонна  кассета,содержаща  ведущий и направл ющие ролики с двум  рулонами магнитной ленты на катушках, охваченные пассиком и расположенные в корпусе кассеты, выполненном с пазами на передней стенке , и крышку, отличающа с  тем, что, с целью повышени  достоверности записи, корпус выполнен с углублением на задней стенке в форме трапеции и двум  окнами в этом углублении .A two-bobbin roll cassette containing leading and guide rollers with two rolls of magnetic tape on reels, covered by a belt and located in a cassette case made with grooves on the front wall, and a cover, characterized in that with a hollow on the back wall in the shape of a trapezoid and two windows in this hollow.
