Multi-channel thermal recording for laser facsimile

摘要

The recording involves transporting a thermally sensitive recording medium in a first direction. A first set of K pixels are written on the medium based on a first group of data. A laser imaging system is transported in a second direction perpendicular to the first direction to position in which N of K lasers overlap and register with N pixels of first set of pixels where N K. A second set of K pixels are written based on a second group of data in which information used to control the N overlapping lasers is identical to information used to write the N pixels of the first set of pixels.
