2.中容量光学贮存系统的发展许多计算机用户和商业应用不需要上述应用的大容量,一般12in～14in直径的单个光盘即能满足要求。早期商业发展的光存系统多为自动文档存贮之类的应用,比特误差率要求较低。1981年,东芝首先在美国全国计算机学会上展示了它研制的Tosfile 2000型光学贮存器系统,一张30cm直径的光盘可以存贮10000页数字化文件。1982年,改进型Tosfile 2100型光存系统上市,成为世界上第一个首先商品化的光存贮系统,单面光盘可贮存A_4格式文件10000页,比特误差率10~(-4)(文件贮存应用的下限)。自1981年以来Tosfile已销售了300
2. The development of medium capacity optical storage system Many computer users and commercial applications do not need the large capacity of the above applications, the general 12in ~ 14in diameter single disc that can meet the requirements. Early commercial development of optical storage systems are mostly automatic document storage and the like, the bit error rate requirements are lower. In 1981, Toshiba first demonstrated its Tosfile 2000 optical storage system developed by the National Computer Society of America. A 30cm diameter optical disc can store up to 10,000 pages of digitized files. In 1982, the improved Tosfile 2100 optical storage system was launched and became the first commercially available optical storage system in the world. A single-sided optical disc can store 10000 A_4 format files with a bit error rate of 10 ~ (-4) (file Lower limit of storage application). Tosfile has sold 300 since 1981
