Abstract
An optical medium uses a single structure or format (such as identical materials, layers and the like) for both a region for holding mastered data and a writeable area. In one aspect, a writeable region of a medium with mastered content is used in connection with paying, collecting or accounting for usage or royalties for proprietary intellectual property embodied in or associated with the content. In one embodiment, the (preferably write-once) writeable area can be used for storing later-written information such as annotations, highlighting, reordering, remixing, modifications, supplements, collections, additions, bookmarks, cross references, hypertext or hyperlinks and the like. Preferably, annotations and similar materials can be associated, by the user, with particular portions or content of the mastered data.
