| Abstract(in English) | Thermomagnetic recording process has been simulated to discuss about the mark expansion and collapse which occured when very small size marks are recorded by magnetic field modulation method. Rectangular shaped marks were assumed to be witten on conventional TbFeCo media. The domains were separated by front and rear walls in the track direction and no side walls in the track width direction. Stability condition of the wall was examined by using Huth's model. It was found that the mark expansion from stray field acting on the wall, and that the smaller stray field lead to the smaller mark expansion. However, the decrease of the stray field was found to influence the stability of marks and make it difficult to form small size marks. The enhancement of the coercive field is necessary for TbFeCo media to record marks smaller than ～lOOnm. |
