Abstract

Thermally-assisted magnetic recording experiments on high-coercivity, perpendicular anisotropy, multilayer Co/Pt media are reported. High performance writability is demonstrated on media that could not be written at ambient temperature. Simulations help to clarify the physical phenomena involved in the thermally-assisted writing process.
