Abstract
A recording medium according to the present disclosure includes a recording layer containing an organic compound having a non-linear optical absorption characteristic. The molar extinction coefficient of the organic compound against light having a wavelength of longer than or equal to 400 nm and shorter than or equal to 405 nm is greater than or equal to 90 mol−1·L·cm−1. In a transient absorption spectrum of the organic compound, an absorbance change ΔAbs at a wavelength of longer than or equal to 400 nm and shorter than or equal to 405 nm is a positive value.
