A time-varying image recording device controls a recording operation for recording time-varying image data in a recording medium. The time-varying image data is sequentially recorded in blocks, and block information containing the total number of blocks and so on is recorded after a series of blocks. It is determined whether a recording process result for the time-varying image data is normal or not. A block information recording capacity, which is a capacity that is necessary to record block information, is obtained based on the number of blocks already recorded in the recording medium, when the recording process result is abnormal. An address of the recording medium, at which the block information should be recorded, is sensed in accordance with the block information recording capacity.
