Ferroelectric Storage Density Tops 20KDVDs/Cubit^2

DeAshcroft writes "As reported in Technology Research News, researchers from Tohoku University, the Japanese National Institute for Materials Science, and Pioneer Corporation have demonstrated a prototype ferroelectric (as opposed to ferromagnetic) storage mechanism with density of 1.5 trillion dots per square inch. No word on why Japanese researchers are using square inches, but the new storage benchmark is the DVD. This is 47 DVD's in a square inch, or over 20KiloDVD's per square cubit. Original paper appeared in the Applied Physics Letters." In related memory news, an Anonymous Coward writes "It appears the the ever present pause between photo's on a digital camera might finally be fixed. A company now claims http://www.mobilemag.com/content/100/102/C1396/ ) to have kicked up the write speed on a compact flash card up to 4MB/sec. This means we lesser photographers can now get the right action shot just by volume alone ;-)"

The really interesting bits, no pun intended

First, they're only currently able to read 25kB/s. Yes, 25 kilobytes per second. They think they can bump up the read speed to 3.75MB/s. But it's the write speed that's curious. The prototype writes at 2.5MB/s, and they estimate they can bump it up to 125MB/s. A medium we can write to faster than we can read!

Second, their goal is 667 terabits per cm^2. Yep, about 2667 times more dense than the 250 gigabits per cm^2 they're claiming.
