Blu-Ray optical discs to be made out of corn

However, Pioneer is sure that corn starch disks will be jolly good for the environment as it is totally biodegradable when buried underground and is loved by bacteria everywhere, particularly with a liberal coating of butter.

Apparently corn starch can be made compatible with Blu-ray, the storage device format supported by Sony and Matsushita. It has a storage capacity of 25 gigabytes, about five times that of a DVD, and offers high performance for recording and playback performance.

According to the Nihon Keizai Shimbun newspaper "most of the 1.2mm-thick disk is produced from a resin made from corn starch, with a single ear of corn able to make about 10 disks". We have never seen an ear of corn creating a disk as normally machines do it, so we will have to take their word for it.
