dc.description.abstractA theoretical approach to predicting the spatial extent of the amorphous to crystalline transition region during the probe recording process on phase-change storage media is presented. The extent of this transition region determines the ultimate achievable linear density for data storage using phase-change materials. The approach has parallels with the slope theory used to find magnetic transition lengths in magnetic recording, and shows that the amorphous to crystalline transition length can be minimized by reducing the thickness of the phase-change layer, by minimizing lateral heat flow, and by maximizing the ratio of the activation energy for crystallization to the transition temperature Ec/Tt.en_GB

dc.descriptionnotes: The first paper to address theoretically the issue of writing resolution in electrical probe recording on phase-change media. The theory combined the thermal, kinetic, and electronic properties of the storage medium in an analytical framework to predict the ultimate writing resolutions of this technology. The theory also provided directions in material selection and design to increase the resolution and hence storage density of this new technology. The work led to invited presentations at on probe-based storage at the IEEE/IoP Magnetics Society Wohlfarth Lecture Meeting, London, April 2005 and at the Seagate Research Conclave, June 2007 at Sprintown, Northern Ireland.en_GB
