什么时候能用磁-光存储器来代替软磁盘?目前看来还为时过早。但出现这种前景已经为期不远了。人们认为,目前在外围计算机存储器上所使用的磁性技术,在八十年代末期将达到它的工艺极限。近来,数字式参数存储单元的需求量越来越高,每年约增长40％,因此必须对新型存储器技术进行研制探索。最近菲力浦公司汉堡研究试验室研制成功一种磁-光存储器(见图1)在大小约为5cm的圆片上可以存储到100M字节,磁盘上的信息可以随时清除掉,也可以随时写入。据该试验室人员介绍:它就象用激光显示和密集磁盘系统上的唱片一样。在这种微观型结构的存储器上,可以用激光在转动的
When is it possible to use magneto-optical memory instead of floppy disks? It seems too early. However, this prospect is not far off. It is believed that the magnetic technology currently used in peripheral computer memory will reach its process limits in the late 1980s. Recently, the demand for digital parameter storage unit is getting higher and higher, increasing about 40% every year, so new memory technology must be explored. Recently, a Philips-Hamburg research laboratory developed a magneto-optical memory (see Figure 1) that can store up to 100 megabytes in a disk about 5 cm in size. The information on the disk can be cleared at any time, Into. According to the lab staff: it’s like using a laser to display on compact disc systems. In this microstructure of the memory, you can use the laser in the rotation
