Fujitsu announced it had developed a multi-layer optical element for a new storage technology known as heat-assisted magnetic recording (HAMR).
Theoretically, HAMR allows for storage of up to 50 terabits per square inch, an unthinkable level by today's standards, much more than 1 terabit per square inch level of today's perpendicular drives.
