Demand of optical discs such as CD-R, DVD-R, BD-R is expanding briskly as they are the means of data storage of texts, still images of digital camera and dynamic picture images of digital television. Although its reliability has been concerned domestically and internationally since short life medium have been broken into the market widely whose quality does not meet the standards, and also that there had been no necessary information regarding the specific standards of longevity. Archive Disc Test Center-NPO Entity have been practicing “optical disc longevity estimation test” since April, 2009 based on worldwide estimation test method of longevity of optical disc. Here we explain expert behaviour on optical disc and longevity estimation test method using acceleration test, and introduce our steps being taken for diffusion of optical disc which is reliable to use.
