Abstract
A data recording apparatus for recording data on a recording medium includes an acceleration detector configured to detect an acceleration which the apparatus is undergoing; a use mode detector configured to detect which one of fixed and non-fixed modes the apparatus is used in; a fall state determination unit configured to determine a fall state of the apparatus by switching fall detection algorithms for detecting a fall of the apparatus on the basis of an acceleration detected by the acceleration detector and the history of acceleration changes in accordance with the detection result by the use mode detector; and a preventive operation controller configured to cause an operation for preventing damage to the recording medium to be performed in accordance with the determination result of the fall state of the apparatus by the fall state determination unit.
