日本夏普公司成功地研制出了使用半导体激光器,利用克尔效应用户可以重写(复制)的光磁盘,并开发了这种光盘的实用化技术。为了完成这种新的光存贮盘,公司开展了以下几方面的研究工作: △新介质TbDyFe系薄膜的研制 1.新式的反射膜构造原来,是把记录介质直接作在玻璃基底上,在上面再加一层保护膜;而夏普则 Japan’s Sharp Corporation has successfully developed the use of semiconductor lasers, Kerr effect users can rewrite (copy) of the magneto-optical disk, and developed a practical CD-ROM technology. In order to complete this new optical storage disk, the company has carried out the following aspects of research: A new medium TbDyFe film development 1. The new structure of the original reflective film is the recording medium directly on the glass substrate, in the Add a layer of protective film above; and Sharp is
