Abstract
A method for balancing pulse energies across a series of write beams in an optical data writer comprises: (a) for each write beam of the series, applying an independently controllable phase delay to the write beam, thereby changing the polarization of the write beam; and (b) for each write beam with changed polarization in the series, directing a selected plane-polarized component of the write beam through a data modulator and onto an optical substrate. In this method the data modulator modulates each write beam of the series irrespective of the tolerance across the series of write beams.
