Waterproof Glass Chip Data Storage by Hitachi

Hitachi Glass Chip can store data for million years

Hitachi demonstrated its capability to encode data onto what it calls “quartz glass”. This innovative invention that makes waterproof glass chip data storage by Hitachi that could store information etched into the material should last 100 million years, the business claims. Diamonds might be forever, but apparently quartz isn’t very far behind.

“Quartz glass” is really a curious material, becoming that quartz is actually a trigonal crystal while glass is regarded as an amorphous solid. Hitatchi’s QG formula is likely to remain a secret, but when the mineral is subjected to higher sufficient temperatures for a long enough time period (at least two,000 degrees Celsius), it loses its crystalline structure and may be made into a glass-like substance referred to as fused quartz. This often extremely pure form of amorphous quartz might be what Hitachi is using.

Writing data to the material is not in contrast to other optical storage technologies. In Hitachi’s demonstration, they utilized four layers of quartz glass. Lasers had been then precisely guided to different locations of the substrate to create microscopic pits which may be later study as binary data. By varying laser focal lengths, the recording device could select which layer to function with.

When the technology has 1 strength at all, it definitely must be durability. Even though we’ll most likely by no means have the ability to test Hitachi’s claim of a 100 million years, the company’s research suggests it’ll last a really, very long time. Accelerated aging tests were performed by exposing the material to blistering temperatures of 1,000 degrees Celsius for two hours; however, the glass remained defiant, failing to exhibit any signs of data degradation.

The new storage medium is anticipated to hit the marketplace in 2015, but do not anticipate to replace your SSDs with data crystals any time soon. Although quartz-etched data may essentially last forever, the amount of data it could hold is fairly miniscule. Currently, the process only packs 40MB per square inch — that is roughly equivalent to the density of a compact disc — but falls woefully short of the 1TB per square inch we see on today’s magnetic storage devices.

The prototype storage device is two centimetres (0.8 inches) square and just two millimetres (0.08 inches) thick and made from quartz glass, a highly stable and resilient material, used to make beakers and other instruments for laboratory use. The chip, which is resistant to many chemicals and unaffected by radio waves, can be exposed directly to high temperature flames and heated to 1,000 degrees Celsius (1,832 Fahrenheit) for at least two hours without being damaged. It is also waterproof, meaning it could survive natural calamities, such as fires and tsunami.

In addition, there was no mention from the material being erasable or re-writable.

Even though the amount of information Hitachi’s quartz technologies can store is little, this might improve with time. Till then, it might be ideal for recording important functions of literature, historical information and such. Just remember although: don’t drop it.
