Many years ago, the magnetic tape were used instead of CD, DVD and flash drives in the Soviet electronic computers for accumulation and storage an information. The reels could be used for next Soviet computers: Minsk-32, SM-4, ES-1030/1035/1040/1050/1036/1045/... and others series Soviet ES EVM. The series of modules for reading the tape was produced in next line: ES-5002, ES-5012, ES-5017, ES-551, ES-5025, ES-5525. The modules were used for reading the magnetic tapes as the peripheral equipment for the CPU electronic computer USSR and had a large weigh about 400-500 kg (every module).
