在过去的5～7年之内,为了满足硬件发展的需要,磁带制造厂之间竞争日益加剧,对磁带和磁盘制造用的磁记录材料。进行了大师的研究。这些研究的结果,使得记录材料的质量独得了显著的提高。虽然整个世界的材料消耗仍然保持在所谓“低噪声材料”水平,但已朝高质量磁粉消耗方面转移。记录材料方面的主要进展包括:增加r-Fe_O_3的密度和提高它的针状形和均匀度,双层磁带,新的高矫顽力 CrO_2,新的外延钴氧化铁.非化学计量r-Fe_2O_3以及各种类型掺钴材料,只要熟悉和了解各种记录、重技术的模型,对这些进展是不难理解的.在材料和有关现象认识方面的进展也是有可能的。为获得较好的完整场的图象,将从其它科学领域对材料进行研究,如单分散系统的化学性和材料尺寸,形状测定的新技术等。
In the past 5-7 years, in order to meet the needs of hardware development, the competition between the tape manufacturers has been further intensified. Magnetic recording materials for magnetic tape and disk manufacturing have been developed. Conducted a master’s research. As a result of these studies, the quality of recording materials has been significantly improved. Although material consumption throughout the world remains at so-called “low-noise material” levels, it has shifted toward high-quality magnetic powder consumption. Major advances in recording materials include: increasing the density of r-Fe_O_3 and increasing its acicular shape and uniformity, a two-layer tape, a new high coercivity CrO_2, a new epitaxial cobalt oxide, a non-stoichiometric r-Fe_2O_3 As well as various types of cobalt-doped materials, as long as you are familiar with and understand the various models of recording and heavy technology, it is not hard to understand these developments, and progress in understanding materials and related phenomena is also possible. In order to obtain better images of complete fields, materials will be studied from other scientific fields, such as the chemical and material dimensions of monodisperse systems, new techniques for shape determination, and the like.
