Abstract
A playback device that creates a virtual package by combining a structural element recorded on a BD-ROM with an additional content recorded on a removable medium. The middleware in the playback device is provided with a file I/O modulethat controls data input/output of the removable medium, in accordance with a request from an application program. When a BD-J application requests writing the structural element of the virtual package and the additional content to be written is an AV stream, the file I/O modulewrites the structural element into one or more allocation units composed of a plurality of continuous empty logical blocks in the removable medium. When the additional content to be written is not an AV stream, it writes the additional content into a normal data area that is composed of a plurality of separately scattered empty blocks in the removable medium.
