RECORDING METHOD AND RECORDING DEVICE

Recording method including: emitting laser-light from optical-fiber-array to record image of writing-units with moving recording target and the optical-fiber-array relatively using recording device 1 including laser-light-emitting-elements and emitting unit 13 including the optical-fiber-array, where optical fibers 12 to guide laser-light emitted from the laser-light-emitting-elements are aligned, wherein diagonal line A'C is longer than B in the image formed by overlapping or adjoining at least part of the writing-units in main-scanning direction, where B is length of 1/2 line width of the writing-unit in main-scanning direction, A is center of edge of the writing-unit in sub-scanning direction, A' is position proceeded from A towards inner-side of the writing-unit by B, line LL' is drawn to include A' and be orthogonal to the writing-unit, diagonal-line is drawn with A' as starting point and to have angle of 45° with line LL', and C is intersection between the diagonal-line and the writing-unit.
