Patent attributes
An optical disk apparatus includes a data conversion unit that converts input video data into record data, a data record unit that temporarily stores the record data in buffer memory and writes on to an optical disk while maintaining data continuity, and a control unit that controls the data record unit and the data conversion unit. The control unit acquires free space of the buffer memory in a reference data unit smaller than a video object unit when the video data is converted into record data in the video object unit, instructs to divide the record data into the reference data units and to store in the buffer memory based on the acquired free space, to convert the video data into record data when the record data is stored, and to divide termination processing data in to the reference data units and to store when a record stop instruction is input.
