According to the Optical Storage Technology Association (OSTA), "manufacturers claim life spans ranging from 30 to 100 years for DVD, DVD-R and DVD+R discs and up to 30 years for DVD-RW, DVD+RW and DVD-RAM", although a manufacturer of 24-karat gold-based DVDs claims lifespans of up to 300 years. Of more conventional manufacturing processes, Taiyo Yuden is frequently recommended for longer durability.
