OLYMPUS OPTICAL Co. Ltd., Hitachi Maxell Ltd. and SANYO Electric Co. Ltd. have developed a Magnet-Optical disk system, iD (Intelligent, Image) PHOTO disk as a next generation system for data storage. The iD PHOTO system is based on the AS-MO (Advanced Storage Magneto-Optical disk) and its media has a high capacity of 730 MB in a 50.8mm diameter single-sided disk. The storage capacity exceeds that of a CD (compact disc), while being the world's smallest rewritable optical disk.Considering its intended role as a portable application, it is important to evaluate its various characteristics under a variety of environmental conditions for its reliability. In this paper, we evaluated the recording and readout characteristics of the iD PHOTO disk under environmental temperatures ranging from -5°C to 60°C and under an accelerating condition. The obtained results proved the iD PHOTO disk to be a suitable recording medium for use as a mobile storage device with a high level of reliability and performance.
