VIDEO TAPE RECORDER ROTATING MAGNETIC HEAD ASSEMBLY

摘要

Use: in the art for a magnetic recording reproducing videofonogramm under conditions disadvantageous tnoj po- fur conditions and for diagnosing channel VTR recording in real time. SUMMARY OF THE INVENTION: In block administered source and receiver optical radiation, polarizer, analyzer and one-nomodovye optical fibers without distorting the polarization, whose number corresponds to the number of video heads which are covered by the magnetic circuit go winding heads on the rotary drum and stacked under a contactless current collector, rotor motor and an electro-optical sensor of its angular position on the axis of rotation of the engine shaft, one ends of which exit at the end of the shaft and optically conjugated to fixedly arranged floor Rizat ohm and the radiation source, and the other to the opposite end of the shaft and aligned with the housing fixed to the analyzer and a radiation receiver connected to the pre-amplifier and shaper of reproduced video signals. 3 yl. . fe
