Abstract

A dual-laser writing scheme is proposed in which an unmodulated short-wavelength read laser augments the writing process effected by a longer-wavelength laser. Apart from increasing the thermal efficiency of the laser marking process itself, the dual-beam writing scheme is shown to decrease the mark width and the recorded mark-length variability. Coupled with the increased resolution of the short-wavelength read spot, these enhancements could improve the performance and packing densities of media.
