This is the last o­ne, I promise. TDK has announced they're changing the names of all their existing optical disc hard-coating technologies to simply "DURABIS." Through a combination of "durability" and "shield" (a very lopsided combination, I might add), TDK managed to reach "DURABIS."

The company already applies the coating to all of their DVD and Blu-Ray discs, so don't expect anything fancy. But the coating looks to be good stuff -- going by the graph they have in their press release, the discs retained jitter percentages of 7% even under a 300-pass steel wool abrasion test. Yikes.

Why did they use "Synthetic fingerprints"? Is it that difficult to just put your fingers on the disc?

Basically, if you push harder or something, the conditions the disc is exposed to would be different than a disc that wasn't pushed on so hard. This would make their test results essentially useless...from a scientific standpoint, anyway. By just putting a standard "fingerprint" on all of the discs, they're able to easily measure the effects it has on each individual disc.
