Plastic memory promises cheap, dense storage

Plastic memory promises cheap, dense storage
(from New Scientist)


A conducting plastic has been used to create a new memory technology with the potential to store a megabit of data in a millimetre-square device - 10 times denser than current magnetic memories. The device should also be cheap and fast, but cannot be rewritten, so would only be suitable for permanent storage.


Obivously, given my interest in digital cameras, I am rather interested in this type of application:

However, turning the polymer INTO an insulator involves a permanent chemical change, meaning the memory can only be written to once. Its creators say this makes it ideal for archiving images and other data directly from a digital camera, cellphone or PDA, like an electronic version of film negatives.


The last sentence is really interesting. If huge amounts of data could be written to it, and this stuff can obviously be made cheap since it is used to coat billions of rolls of film today, it would help solve the problem of storing pictures, and the card reader would be a type of a scanner to transfer the permanent copy of the raw image perfectly onto a device capable of altering it - a computer equipped with Photoshop.
