Abstract
We have studied the feasibility of a recording process using electrical mic ro-tips on phase change materials. Calculations and experiments demonstrate that the tunnelling probe is a sufficient heater source for this applicati on. Difficulties remain in the control of the writing current during pulse application and in the detection of resistivity change with the tunnelling probe. WORM memory was carried out with a data density up to 10 Gbit/in(2). Solution for reversible storage on phase change materials are proposed. (C ) 1999 Elsevier Science B.V. All rights reserved.
