Abstract

A system for writing data using an electron beam to change the structure of a small section of a storage medium and includes at least one focused electron beam source. The duration of a write cycle of the focused electron beam source is controlled at least in part on an estimated or measured amount of charge transmitted by the focused electron beam source to the storage medium during the write cycle.
