ABSTRACT:
A system that includes multiple, elliptical writing spots produced by a single, integrated laser diode array head. The beams, generated by the array and shaped by beam shaping optics into the elliptical spots, are scanned across a thermal media writing plural lines at the same time. The elliptical writing spots have an energy profile and a concatenated, angular orientation and staggered arrangement that, due to the thermal interaction of the spots on the media, creates substantially Gaussian thermal profiles in the media.
