Abstract
Recording method including emitting laser light from optical fiber array to record image formed of writing units with moving recording target and the optical fiber array relatively using recording device including laser light-emitting elements and emitting unit including the optical fiber array where optical fibers configured to guide laser light emitted from the laser light-emitting elements are aligned, wherein the image includes convex-concave shapes formed by aligning convex portions relative to, as standard, vertical line to the writing units where the vertical line includes the nearest contact points at endmost side of the image in sub-scanning direction where the image is formed by overlapping or adjoining at least part of the writing units in main-scanning direction and satisfies formula below:≤0.4where T is average height of the convex portions and X is minimum distance between centers of the adjacent writing units in the image.
