Abstract: A recording apparatus of this invention detects the state of management information, which pertains to a recording address of an image signal, and which is reproduced from a disk-like recording medium having a first area for the image signal and a second area for the management information. On the basis of the detection result, management data is reproduced from the first area of the disk-like recording medium. On the basis of the management data reproduced from the first area, the management information reproduced from the second area is modified. A modify unit records the modified management information in the second area.

Abstract: A recording apparatus records, in a recording medium, moving image data and management information, concerning the moving image data and generated in accordance with the recording operation of the moving image data. In accordance with a recording start instruction, the recording apparatus starts recording of the moving image data and records, in the recording medium, information indicating that the management information has not yet been recorded. In accordance with a recording stop instruction, the recording medium stops recording of the moving image data, generates and records the respective management information, and updates the information indicating the recording status of the management information. If a decrease in electric power is detected during recording of the moving image data, the recording apparatus stops recording of the moving image data, without updating the information indicating the recording status of the management information.
