25 Gigabytes of storage from one ear of corn!

Researchers at consumer electronics maker Pioneer have developed an optical disk made of corn starch resin that can hold 25 gigabytes of data,a dn is almost completely biodegradable. A single ear of corn can produce 10 discs. Also if the starch polymer is incinerated it will not eliminate any dioxins (think of vladimir yushenkov's poisoning), or other harmful chemicals. The disc are even edible, but with an extra durable 0.1 mm coating it is imposible to chew. (Baseline, 038, December 2004)
