Future Generation MO Media From A Manufacturing Point Of View

Abstract

MO media technology is now on the first step of mass production. For a "Big Bang" of MO industry, we should add more fascinating points for users. The first priority is to realize low cost technology. Cost consists of materials, throughput and yield. The second priority is to achieve a large memory capacity using techniques like a mark edge recording, short wavelength lasers, magnetic super resolutions (MSR) and so on. High speed capability is also important. Especially, MO disk requires an overwriting capability. For future generation MO disk, a lot of schemes are proposed and attract many researchers. Here, I'll try to check such schemes from an above mentioned point of view.
