20 layers
25GB/layer
500GB
A 20-layer optical disc is now viable, following research by our team of engineers at Pioneer HQ, Tokyo. Each layer of the disc can store 25GB of information to provide a mammoth 500GB of storage.
The news follows the International Symposium on Optical Memory (ISOM) and Optical Data Storage, held during July in Hawaii, where Pioneer Corporation presented its research, defining draft specifications for the 500 GB disc.
