A data stream generating apparatus for a recording/replaying apparatus includes a storage unit and a control module. The control module generates a video elementary stream and an audio elementary stream from inputted video data and audio data to store in the storage unit, and generates and stores a navigation pack in the storage unit. Also, the control module determines an output order of the navigation pack, a plurality of video packs generated from the video elementary steam and a plurality of audio packs generated from the audio elementary steam based on a unit size of an outputs data stream, a data quantity of the video elementary steam and a data quantity of the audio elementary steam, while updating the navigation pack. Then, the control module reads out from the storage unit and outputs the navigation pack, the plurality of video packs, the plurality of audio packs as an output data stream based on the output order.
