Abstract

The light energy necessary for the precure process is held by the RFID at the holographic memory. The controller acquires the light energy corresponding to the temperature of the recording position detected by the temperature sensor out of the precure information acquired by the RFID reader. The exposure time (light emitting time of LED) Te in the precure process is calculated based on the calculating equation Te (sec)=En (joule)/Pd (watt) from the energy En and the intensity Pd of light irradiated onto the recording position detected by the light detector.
