Abstract
An optical data storage system records pulse width modulated data as a series of contiguous and overlapping circular marks. A minimum number of circular marks are used to record the desired run length. Circular marks which overlap by greater or equal to one half the diameter of the circular mark are recorded using two different laser power levels. The result is that thermal buildup in the medium is kept to a minimum and the edge transitions are accurately positioned.
