内容記述 |
Specifications of patterned magnetic recording media for tera-bit recording were designed as an extension of perpendicular magnetic recording. Effective thermal stability of the magnetic dots with perpendicular anisotropy was estimated using the magnetic field where magnetization reversal begins in the magnetic dot array by the applied perpendicular field. The estimated magnetic properties of the media with an areal density of 1 Tbit/in2 were expected to be realized with known hard magnetic materials such as Co-Pt and FePt alloys. Effects of the size and shape of dots and the spacing between dots on the magnetic reversal properties were investigated using a micromagnetic simulation. It was found that the spacing between dots would impose strong restriction on the achievable recording density. Recording simulation on a designed patterned medium indicated possibility of realization of 1 Tbit/in2 recording. |
