Our colleagues at http://www.consolejunky.com have let us know today that the ECMA has now approved the UMD (Universal Media Disc) Media Format as an iSO optical disc standard, giving it the title ECMA-365. As detailed http://www.ecma-international.org/publications/standards/Ecma-365.htm, there are (2) standard UMD types- Type A (0.9GB) and Type B (1.8GB). This is indeed good news as the UMD Media Format is now open publically, and both companies and curious developers/individuals can now download the http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-365.pdf in PDF Format to learn more on exactly how UMD works!
