Optical data storage is now well into the second decade of continuing market and technology expansion. Media removability, which is the main attribute of this technology, presented the optical recording industry with unmatched opportunities and also new challenges. On the one hand, data interchange between the media and drives from different sources becomes a major concern, which can only be solved if international standards for all optical recording disk/cartridge are available. Many standards organizations, with the help of world wide industrial support, took up the challenge, and numerous international standards were established which are now being adapted. On the other hand, copy protection technology must be developed to prevent illegal copying and distribution of contents using this removable media. This need is accentuated by the proliferation of low cost CD and now DVD disks replication means and the availability of recordable and rewritable CD and DVD devices. This paper provides an update of the brief summary of the current status of the international optical disk standards published earlier and a brief review of the copy protection technology.
