Simulation of magnetic recording process of amorphous continuous media

It is known that amorphous continuous media such as TbFeCo have extremely low noise characteristics because of the structure of the continuous grainless medium. There is great interest in the use of amorphous media in magnetic recording. This study investigated the recording characteristics of the amorphous continuous medium by computer simulation using the Landau-Lifshitz-Gilbert equation. It was shown that the transition of the continuous medium is very sharp and the noise level very low. It was also shown that the recorded magnetization pat terns of the continuous medium are distinct at the high recording density of 380 Gbit/inch(2). We concluded that the continuous medium has great potential for use in ultra-high density recording.
