Patent ID: 6995785

Claim:
A record method of recording an image onto a record medium by exposing to laser light for drawing while relatively moving the record medium supported on a plate and a record head for emitting the laser light for drawing to a surface of the record medium in a main scanning direction and a sub scanning direction along a surface of the record medium through a move guide mechanism, comprising steps of: applying laser light for focus to the record medium in a noncontact manner, wherein the laser light for focus does not leave traces having an effect on drawing by applying the laser light for drawing on the record medium; and correcting misregistration between a focus position of the laser light for drawing emitted from the record head and the record medium based on a value detected by the detecting step so as to keep exposure conditions of the laser light for drawing from the record head to the record medium at a reference value; wherein the record medium is a binary sensitive material having a density gradation characteristic that one of maximum density and minimum density are selectively provided in response to input energy according to whether the input energy is larger or smaller than a threshold value.
