物理研究所是1974年开始磁记录研制工作的。早期,为了了解我国磁带与国外磁带性能之间的差距,开展了磁粉和磁带的剖析工作,熟悉磁带的制备工艺以及从磁学和磁记录的基本原理寻找磁带的电磁性能和它的基本磁性参数之间的定性关系等等。在此基础上,研制了一些磁记录材料,并建立了制备材料的连续生产设备等。 Institute of Physics was started in 1974 magnetic recording work. Early, in order to understand the gap between China’s tape and foreign tape performance, carried out the analysis of magnetic powder and tape, familiar with the tape preparation process and magnetic and magnetic recording from the basic principles to find the tape’s electromagnetic properties and its basic magnetic parameters The qualitative relationship between and so on. On this basis, some magnetic recording materials have been developed, and a continuous production equipment for preparing materials has been established.
