本文介绍了高密度数字磁记录用Co/Cr磁记录介质材料的初步试验研究结果。Co/Cr磁膜介质系用真空蒸发沉积法制作,磁记录试验在磁盘机上进行。并在相同的写读试验条件下,与保加利亚的γ-Fe_2O_3介质磁盘进行了特性比较的结果表明,Co/Cr磁膜介质的特性优越,是一种具有良好使用前景的磁记录介质材料。
This paper presents the results of a preliminary experimental study of Co / Cr magnetic recording media for high-density digital magnetic recording. Co / Cr magnetic film dielectric vacuum evaporation deposition method, magnetic recording test on the disk machine. The results of comparison with the γ-Fe_2O_3 magnetic disk in Bulgaria showed that the magnetic properties of the magnetic medium were good, and it is a good magnetic recording media material.
