Abstract
Abstract A recording apparatus includes a recording unit having a plurality of dot forming portions disposed in a plane, a carriage which moves incrementally in a direction normal to the plane of dot forming portions, and a laser generator mounted on the carriage. The generator has a semiconductor which radiates a laser pulse in a direction substantially perpendicular to each dot forming portion of the recording unit.
