磁盘是电子计算机外存储器之一,与铁氧体磁芯存储器,IC存储器等主储存器相比,其存贮容易大,价格便宜。自磁盘实用化以来,经历了20年,它是把γ—Fe_2O_3 磁粉和粘合剂混合,涂布到铝合金基片上的涂布型媒体.随着电子计算机的普及要求磁盘高记录密度和大存贮量.在努力提高涂布型磁盘性能的同时,突破涂布型磁盘的界限,使记录密度飞跃提高,对不含粘合剂的非磁性连续媒体-金属镀膜,氧化物磁性薄膜等记录媒体,进行了研究.下面将对涂布型磁盘的发展经过,今后的动向以及连续记录媒体进行介绍.
Disk is one of the electronic computer external memory, and ferrite core memory, IC memory and other main storage compared to its easy to store large, cheap. Since the practical use of the magnetic disk, after 20 years, it is a coated medium that is a mixture of γ-Fe 2 O 3 magnetic powder and a binder coated on an aluminum alloy substrate. With the popularization of electronic computers, high recording densities and large In addition to efforts to improve the properties of coated magnetic disks, the breakthrough of the limits of coated magnetic disks has led to a dramatic increase in recording density, recording on non-magnetic continuous media without adhesive, such as metal coatings and oxide magnetic thin films Media, conducted a study of the following will follow the development of coated magnetic disk, the future trends and continuous recording media are introduced.
