Description

ве опорного сигнала. Усиленный результативный сигнал подаетс  на привод 1,стабилизиру  скорость вращени  диска ВГ. На формирователь 5 с зажима 7 также приходит телевизионный сигнал, синхроимпульсы которого используютс  дл  получени  сигнала временной ошибки. Коммутатор 6 в режиме записи информации соедин ет формирователь 5 с усилителем 4, и тогда усиленный сигнал временной ошибки также поступает на привод 1, вли   на скорость врашени  диска ВГ в тесной св зи с изменением положени  синхроимпульса записываемого сигнала. Записываема  информаци  в результате практически не подвергаетс  воздействию искажений, возникаюш ,их при изменении временного положени  синхроимпульсов.the reference signal. The amplified resultant signal is applied to actuator 1, stabilizing the rotational speed of the VG disk. A television signal also arrives at shaper 5 from terminal 7, the sync pulses of which are used to obtain a time error signal. The switch 6, in the information recording mode, connects the driver 5 to the amplifier 4, and then the amplified time error signal also goes to the drive 1, affecting the speed of rotation of the VG disk in close connection with a change in the position of the sync pulse of the recorded signal. As a result, the recorded information is practically not affected by the distortions that occur when changing the time position of the clock pulses.

Схема описываемого устройства достаточно проста и позвол ет уменьшить вли ние накапливающейс  временной ошибки на качество записываемой информации.The circuit of the described device is quite simple and allows reducing the effect of the accumulating time error on the quality of the recorded information.
