Title:
MECHANICAL DATA PROCESSING
Document Type and Number:
WIPO Patent Application WO2002061734
Kind Code:
A3
Abstract:
Described is a method for erasing data recorded in a data storage device in which a data bit (120) is written onto a surface (90) by applying a first combination of energy (Ew) and force (Fw) to the surface via a tip (40) to form a pit in the surface representative of the data bit by local deformation of the surface. The method comprises applying a second combination of energy (Ee) and force via the tip to pre recorded deformations of the surface to be erased to substantially level the surface.
