Data Archive Technology:

Spatially Distributed ECC
OK, this one sounds even more complicated. But again it's really quite simple. ECC stands for 'Error Correction Code' and it's the way data drives minimize the loss of data on the media. It's a technique for 'sprinkling' the data, with high mathematical accuracy, onto the media. 

The Problem
Over time, all magnetic and optical media, whether recorded by tape or disk drives, lose small amounts of data due to weak bits that cannot be reliably read later on.

The Traditional Solution
Most drives use Error Correction Code (ECC) which is a technique for sprinkling bits along the data track to permit reconstruction of original data when occasional bits are missing. The resulting reconstituted data provides significantly improved data reliability.

Our Solution
In contrast to single channel heads, our disc drives have multi-channel heads that record data multiple tracks at a time. When applying ECC, our drives sprinkle the bits over all these tracks. The result is an exceptionally robust ECC that is so strong it is possible to scratch off an entire track and not lose any data. This is called spatially distributed ECC and it enables our drives to deliver bit error rates lower than 1 unrecoverable bit in 1019th bits written. This is 10,000 times better than your primary data storage device, the hard disk drive, and 100 times better than the most expensive tape drives.
