Compact discs could soon be replaced, after scientists created a finger-tip sized device. The device can store up to 1 GB of information and around 12 hours of music. The small sized tab could be on the market within 5 years.
The small device acts just like a CD and it can store data permanently. It will be very cheap but the drawbacks are that it may only have one time usage. It uses an unknown property of plastic coating called Pedot. Usually used as anti-static.
The small tab was developed by the University of Princeton, New Jersey together with Hewlett-Packard. Music experts have dismissed the find as not revolutionary and point to Vinyl still being a very popular medium. And say the CD will still be here. Source
