a data recording device and a camera device in which , while using a disc drive not employing tracking servo , destruction of recorded data is prevented against an impact applied during data recording . the data recording device or a camera device includes a recording unit 32 for recording data on the disc - shaped recording medium without employing tracking servo provided in the inside of a casing , an acceleration sensor 33 for detecting an impact applied to the casing and a control unit 28 , 31 , 36 for controlling the recording unit for discontinuing data recording on the disc - shaped recording medium if an impact exceeding a pre - set value is detected based on detection results from the acceleration sensor 33 . by discontinuing data recording on the disc - shaped recording medium on detection by the acceleration sensor 33 of an impact exceeding a pre - set value , it becomes possible to prevent destruction of recorded data on the disc - shaped recording medium and failure in recording .
