ABSTRACT:
A method of recording information by projecting electromagnetic radiation to a recording medium, wherein a first electromagnetic radiation in a wavelength region to which the recording medium has its principal sensitivity is uniformly imparted to the recording medium, and, while the hysteresis remains, a second electromagnetic radiation a wavelength longer than said first wavelength region and which bears thereon the information to be recorded is projected onto the recording medium, thereby increasing the sensitivity of said recording medium with respect to said second electromagnetic radiation.
