Title: A METHOD OF THERMALLY-ASSISTED DATA RECORDING AND A RECORDING APPARATUS
Abstract:
A method for thermally-assisted magnetic recording at an areal density above 100 Gb/in2 combines thermo-magnetic writing and optical or magnetic reading. In order to increase the stability of the recorded information, writing is carried out at an elevated temperature on a medium with a very high coercivity at room temperature. The magnetic write (76) head determines the trackwidth (44), allowing very small trackwidths.
