目前,已研制出一种使用磁光盘的可擦除视频磁盘记录器,并证实它可写、读和擦除视频信号。在这种试验记录器上,在录放数字视频信号的实时内,可获得高于100Mbits/sec 的比特率。视频信号编码采用3:1:0单元编码系统。该系统包括误差校正码和音频信号调制脉冲码。视频信号被分成4个信通,两个单面磁盘上分别记录2路信号。记录时间为10分钟,存取时间小于0.5秒。本文叙述磁光盘的两种用途:较短广播节目的传输存贮、动态画面和计算机制图的存贮。由于磁光盘存贮器具有可擦除特性和较短
Currently, an erasable video disk recorder using a magneto-optical disk has been developed and confirmed that it can write, read and erase video signals. In this test recorder, in the real-time recording and playback of digital video signals, bit rates higher than 100Mbits / sec are available. Video signal encoding using 3: 1: 0 cell encoding system. The system includes an error correction code and an audio signal modulation pulse code. Video signal is divided into 4 letters, two single-sided disk were recorded 2 signals. Record time is 10 minutes, access time is less than 0.5 seconds. This article describes two uses of magneto-optical disks: transmission storage of shorter broadcast programs, storage of motion pictures and computer graphics. Since magneto-optical disk storage has erasable characteristics and is short
