ABSTRACT:
The time duration of an erasing cycle is shortened and "raster burn" is reduced by first applying potentials which result in a substantially uniform charge over the storage surface by means of secondary electron redistribution. This causes the storage target surface to assume a substantially uniform "white" level. Thereafter, the charge on the storage target surface is reduced to a substantially uniform "black" level.
