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.
