Abstract
A multimedia information recording device is used for efficiently recording multimedia information () file storage area () on a recording medium (). From the multimedia information given to the device, a data body DB and control information (HD and FD) are created and given to a file storage area writing section () where the data is written in parallel at a time on a free cluster in the file storage area. In the free area of each cluster where the data is written, dummy data is packed by a dummy data adding section () to absorb the difference between the first position of a cluster and the first position of the data in the cluster. Thus, data rewriting to eliminate this difference is avoided. Information for connecting plural clusters where data is written is created by a multimedia information file creating section (), and the multimedia information is recorded in a multimedia information file on the recording medium.
