光盘存储产业技术的发展已有20多年的历史。1981年由荷兰Philips公司和日本Sony公司提出激光数字音乐唱片(CD-DA)红皮书标准至今,光盘本身大小120mm直径没有变化,但是每张光盘的存储容量从CD类(表一)的650MB提高到现在DVD的17GB(双层双面记录),在这18年中,记录容量整整提高了26倍多,几乎平均每年就要提高1.45倍。 上述数字一方面反映了光盘技术与产品的发展
The development of optical storage technology has been more than 20 years old. In 1981, the CD-DA Red Book Standard was proposed by the Philips company of the Netherlands and the Sony Corporation of Japan. The size of the disc itself has not changed by 120mm diameter, but the storage capacity of each disc has been increased from 650MB of the CD category (Table 1). Now 17GB (double-layer double-sided recording) of DVD, in this 18 years, the recording capacity has increased more than 26 times, almost an average of 1.45 times per year. The above figures reflect the development of optical disc technology and products on the one hand
