自从1941年发明了电视机以来,人们就想把节目记录、保存和编集起来。1956年美国制成了第一部实用磁带录像机,随后日本统治了录像机工业。录像机是现代高技术的综合产物,它体现了一个国家的工业技术水平。例如它的磁头工作间隙只有0.6μm,相当于红光波长,只能用光学显微镜测量。目前,家用磁带录像机有:Beta、VHS、YHS-C和8mm几种系列。
Since the television was invented in 1941, people wanted to record, save and compile programs. In 1956, the United States made its first practical videotape recorder, after which Japan ruled the videocassette industry. VCR is a comprehensive product of modern high technology, which reflects a country’s industrial technology. For example, its head working gap is only 0.6μm, equivalent to the red wavelength, can only be measured with an optical microscope. Currently, home video tape recorders are: Beta, VHS, YHS-C and 8mm several series.
