Microwires Can Replace The DVD-ROM

neutron_p writes "A former Soviet Union military development finds its use in modern technology and still remains fascinating." The development comes in the form of a flexible microwire, 10 micrometers thick and 10cm long, with a metal body and a glass coating, which the linked article says "can store 10 Gigabytes of information. It is possible thanks to their magnetic properties. Anyway, it's not that easy. Researchers say that the greatest difficulty will be with the reading of information."

Uh... basic mistake.

From the article: The researchers calculate that a 10 cm long microwire can carry out 10 million divisions or cells and in each one of these a byte can be stored. In order to store the byte, each one of these cells is magnetised in one orientation or the other.

When they say "byte" here, they seem to mean "bit". (for the script kiddies, there are 8 bits to the byte) Also, they're referring to "10 million divisions" not "10 billion divisions".

So it wouldn't be 10 gigabytes, it would be more like 1.2 megabytes, or roughly 122k/cm. To store 10 gigabytes, it would have to be over 838m long, or over 2750 feet.

Frankly, I'm not horribly impressed.

Not to mention, this is just in theory. It hasn't actually been done yet.
