1、电子文件使用的载体介绍。随着电子计算机技术的发展,信息数字化记录技术也在不断地发展。目前,信息数字化记录载体有磁性、光学性和磁光性等类型。磁性记录应包括磁记录器和磁记录介质。其写入原理和过程是:从磁记录器的磁头缝隙里向外发散一个磁场,它的强度和方向随着记录磁头线圈里的电流而相应变化。这 1, the introduction of the carrier of electronic documents. With the development of electronic computer technology, information digital recording technology is also constantly evolving. At present, the information digitized record carrier has magnetic, optical and magneto-optical types. Magnetic recording should include magnetic recorders and magnetic recording media. The writing principle and process are: Disperse a magnetic field outward from the head gap of the magnetic recorder, and its intensity and direction change correspondingly with the current in the recording magnetic head coil.
