Abstract
A laser beam emitted from a stripe-shaped area of a laser diode is expanded in its low divergence axis to match a length of a modulator which individually modulates different regions of the beam to produce a plurality of individually modulated beam portions which are focused by a lens onto a recording medium, such as dye and receiver sheets, to effect data recording. The modulator may be a row of LCD cells, an acousto-optic modulator, or a row of micromirrors.
