OLYMPUS OPTICAL Co. Ltd., SANYO Electric Co., Ltd., and Hitachi Maxell, Ltd. in July 1999 announced the joint development of a 50 mm-diameter magneto-optical disk system, a new iD (intelligent or image) PHOTO format standard, together with an associated logo for this system standard, as a next generation medium for digital still cameras. The system is based on the AS-MO standard, and is a very suitable application format for digital still cameras. Despite the world's smallest rewritable optical disk of a 50 mm diameter, it has a high capacity of 730 MB, which exceeds that of a CD. It's data can be rewritten over 1 million times at a speed of more than 20 Mbps, and stored for long periods.
