CDs when they came were cool, you could store 600+ MB of data, portable, light-weight, more reliable than floppies and good looking (unlike ugly tapes). Soon we wanted more and got DVDs, which can store 4.7GB on one side and mass produced industry-strength DVD’s can double that capacity by writing on both sides.

The two big concerns I have on CD/DVDs, are that:
1) They are not bio-degradable, the chief raw material that goes into making one of these shinny beauty’s is “black“ oil
2) To destroy a CD/DVD that contains my sensitive data is very difficult and dangerous; you can break a CD/DVD but you have to extremely careful that it doesn’t cut your skin.

Last week I saw a major announcement that solves both these problems. Sony on April 15th, announced a paper-made disc that can store 25GB!. It is based on Blue-Ray and the disc is made of more than 50% paper, so can be recycled. It can be easily cut with scissors to destroy it permanently.
