Abstract:
1. A content data storage device which includes a plurality of nonvolatile memories to which content data is written per page, and stores content data including at least video data and audio data in the nonvolatile memories, comprising: a write buffer memory which receives and stores the video data and the audio data, wherein the write buffer memory includes contiguous pages, each page with a predetermined data size for storing the audio data; a storage unit which includes a plurality of nonvolatile memories, the storage unit storing the video data and the audio data outputted from the write buffer memory in the plurality of nonvolatile memories; and a write controller which determines when the audio data stored in one page of the continuous pages reaches a preset amount, where the preset amount is less than the predetermined data size, and supplies the write buffer memory with a command to add dummy data to the audio data stored in the one page from the preset amount until a combined size of the dummy data and the audio data reaches the predetermined data size; wherein the write controller further commands the write buffer to output the one page as resultant data; and wherein the write controller signals the storage unit to store the resultant data including both the dummy data and the stored audio data.
