Abstract
To achieve an object to imprint optical data by an appropriate amount of imprinting light, a data recording apparatus includes a correction device for preventing the amount of light for imprinting optical data from varying as a result of an image plane size or an imprinting area being switched. The correction device includes a device for varying the amount of light emission by varying a light emission time and intensity, and an electric current used for light emission, an optical device adjusted to an appropriate transmittance in an imprinting optical path.
