Claim Text:
1. A drawing apparatus which applies energy to a surface of a medium by irradiating a laser beam onto a position of the medium while moving the irradiated position in a drawing direction, to draw a line segment on the surface of the medium, comprising: a laser which irradiates the laser beam; a laser beam driver that drives the laser beam to move the irradiated position in the drawing direction; a controller which controls the laser beam driver and an irradiation of the laser beam, wherein the controller controls the laser beam driver to drive the laser beam to move the irradiating position in the drawing direction, and wherein the controller determines a start point of the line segment to be drawn in the drawing direction, and controls the irradiation of the laser beam to begin to apply energy of a drawing output level to the medium starting from a point located backward by a predetermined distance, relative to the drawing direction, from the start point of the line segment to be drawn, and continues to apply the energy having the drawing output level to the medium over a length of the line segment to be drawn, the predetermined distance being such that color is developed in the line segment, by the irradiation of the laser beam to apply energy to the medium, at the start point.
