1 光盘简史由于计算机用的磁介质存在着不能长期保存、存储容量有限,跟不上日益增长的海量存储要求的固有弱点,因此1966年首次提出光存储器概念。但是可重写介质材料难于解决,于是70年代转入介质材料易于解决的只读光盘和一次写光盘的研究。1978年菲利普公司正式推出视盘商品。1983年日本首次开发成功CD-ROM光盘机,1984-1985年这 A Brief History of Optical Discs The concept of optical storage was first proposed in 1966 because of the inherent weakness of computer-based magnetic media, which can not be stored for long periods of time, has limited storage capacity and can not keep up with the ever-increasing demand for mass storage. However, rewritable dielectric material is difficult to solve, so the 70s into the media material easy to solve the CD-ROM and write a CD-ROM research. In 1978 Phillip formally launched video disk products. In 1983, Japan first developed a successful CD-ROM drive, 1984-1985 this
