OPTICAL DISC LABEL PRINTER, THERMOSENSITIVE RECORDING PRINTER AND THERMOSENSITIVE RECORDING METHOD

摘要

A thermosensitive printer is provided with semiconductor lasers (1a-1c); a polygon mirror (7), which collects laser beams emitted from the semiconductor lasers (1a-1c) onto a recording medium (10) as a beam collected spot and makes the collected beams perform scanning in a main scanning direction; and a control section (9) for controlling laser beam output. At the time of forming an image composed of a plurality of pixels on the recording medium (10) by using the laser beams, a spot diameter (D1) of the beam collected spot in the main scanning direction and a spot diameter (D2) of the beam collected spot in a sub-scanning direction satisfy an inequality of D1/D2=1/2. Thus, a recording system wherein high-speed thermosensitive recording is performed without deteriorating the power density of the beam collected spot and power control is not made complicated is provided.
