随着这门技术的发展和力图走向市场,人们在光学数据存贮方面的活动正在加速,兴趣也不断提高。一般地说,光学数据存贮器件类似于商品唱片唱机和视频唱片播演机,不过和只播不录的商品器材不同之处是,存贮系统也可用激光束来写入新数据。用这项技术有希望以较低的成本在一个小的坚固器件上给出大的存贮容量,并能随机存取。存贮介质是一种可拆装的、可望廉价的部件,它的使用和贮藏是方便的。低成本、不可擦除、不可重录存贮器的应用遍及整个数据处理范围,从数据量少的办公室设备,传真和电子邮政,直到大型系统的 As this technology evolves and seeks to get to market, people are accelerating their interest in optical data storage and increasing interest. In general, optical data storage devices are similar to commercial disc players and video record players except that the storage system can write new data with laser beams as well. It is hoped that this technique will give large storage capacity on a small, rugged device at a lower cost and be randomly accessible. Storage media is a removable, inexpensive component that is easy to use and store. Low-cost, non-erasable, non-rewritable memory applications span the entire range of data processing, from less data-intensive office equipment, fax and e-mail, to large systems
