Abstract
An optical medium uses a single structure or format (such as identical materials, layers and the like) for both a region for holding information content-mastered data and a writeable area. In one aspect, a writeable region of a medium with information content-mastered data 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, a key permitting access to some or all content, preferably when combined with a disk serial number, is stored in the writeable area, which is preferably user-inaccessible.
