A disk recording device includes an encoding unit, a control unit, and a structure which encodes a video signal in analog format and records it upon a DVD. Furthermore, the control unit includes a bit rate control unit which controls the bit rate during encoding by the encoding unit to any one of a plurality of video recording modes whose bit rates are different, a bit rate changeover control unit which selects one or more of these video recording modes and controls the timing of the changeover between them, and a ROM in which control data for the video recording mode is recorded in the format of a data table. The bit rate changeover control unit inputs the appointed time period for video recording the video signal, and the capacity which can be recorded upon the disk, and calculates the timing for the changeover between video recording modes.
