"Our introduction of high-speed 30 nanometer class NAND late last year served as an initial pathway for stimulating acceptance of the new high-performance toggle DDR technology, " said Dong-Soo Jun, executive vice president, Memory marketing, Samsung Electronics.

The key to cracking that nut is apparently the new thermal assisted optical element Fujitsu's developed, allowing for an ultra-tiny sub-hundred nanometer optical spot size, which in turn should enable recording on the one terabit (not byte, let's not get crazy here) per square inch level.

By first splitting the molecules into very small lines and then using an equally rare nanoimprinting technology to put them into circular tracks, HGST can create platters with a 10 nanometer-wide bit pattern that's twice as dense as current hard drives.
