Abstract: A recording conditions controlling method for an optical memory device of the present invention includes the steps of: a reproducing condition controlling step for projecting light on an optical recording medium on which information is recorded and measuring a reproducing signal read so as to control a recording condition optimum; and a recording condition controlling step for controlling a recording condition in accordance with the reproducing condition thus optimized. This prevents destruction of an optical disk by heat, which occurs when the heat capacity of the optical disk is small and/or when the environment temperature is high, thus realizing a stable control of recording light quantity.
