Storage domain相关介绍：

The 21st century is a high-tech era of informatization and digitalization. The requirements of ultra-high density storage and high-speed transmission of information promote the further development of information technology. Advanced electronic computers, surveillance cameras and automatic equipment for acquiring, processing, storing and transmitting all kinds of information all need storage. Information storage includes magnetic information storage, magneto-optical information storage, all-optical information storage and phase change storage. Magnetic memory such as magnetic disk, magnetic head, magnetic drum, magnetic tape, etc. uses the ferromagnetic properties of magnetic materials to store information. The targets used for sputtering film recording include chromium base, cobalt base, cobalt iron base, nickel base and other alloys. Optical recording target mainly refers to sputtering target used in optical disc manufacturing. The optical disc with simple structure is mainly composed of substrate, recording layer, reflective layer, protective layer and printing layer. The optical disc with complex structure has more than 10 layers. The recording layer, reflective plate and protective layer are mainly related to the sputtering target. Phase change storage materials mainly include germanium antimony tellurium, scandium antimony tellurium, Gast, etc.

Ketai new materials has been engaged in the coating industry for many years. Since the first generation of optical storage, we have begun to supply all kinds of storage coating materials. Our third generation of semiconductor storage materials have been adopted by advanced laboratories and large enterprises.
