External sensor data is efficiently recorded without changing a resolution or a sampling rate. In a data recording device, an acquired data property storing unit stores, as a data property, an external environment in which external sensor data is to be recorded, an external sensor data property recognizing unit recognizes, as a data property, the external environment corresponding to the external sensor data, a data recording necessity determining unit determines, based on the data property recognized by the external sensor data property recognizing unit and the data property stored in the acquired data property storing unit, whether the external sensor data is required to be recorded, and a data recording unit records the external sensor data when it is determined by the data recording necessity determining unit that the external sensor data is required to be recorded.
