Submission + - How Far Can Perpendicular Recording Go? (conceivablytech.com)
peterkern writes: Samsung has a new hard drive and says it can now store 667 GB on one disk, which comes out to be about 739 Gb/inch2. That is more than five times the density when perpendicular recording was introduced back in 2006 and is getting close to the generally believes soft limit of 1 Tb/inch2. It’s great that we can now store 2 TB on one hard drive and 3 TB hard drives are already feasible. But how far can it go? It appears that the hard drive industry may start talking about heat-assisted magnetic recording soon, again.
