Abstract
A data assurance method controls an optical head according to the difference between the device temperature and the temperature of inserted removable optical storage media. A rate of temperature change c is calculated from the output of a temperature sensor which detects the device temperature, and then the temperature of the media is estimated. A transition is made to special processing, and a return is made from special processing in a state with a temperature difference to normal processing depending on the rate of temperature change. Consequently a return to normal processing can be made safely and quickly.
