目前盒式录像带的最短记录波长是1.2～1μm。下面将要介绍金属粉涂敷的磁带(MV型)和蒸渡磁带(VV型)。这些磁带当记录波长为1μm时,与目前的磁带相比,MV型的输出是+12dB,VV型输出是+23dB,可用作高密度记录。
At present, the shortest recording wavelength of the video tape is 1.2 to 1 μm. The metal powder coated tapes (MV type) and steaming tapes (VV type) will be described below. These tapes have an output of + 12dB for the MV type and + 23dB for the VV type when compared with current tapes at a recording wavelength of 1μm and can be used for high-density recording.
