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.
