Your next hard-drive could be a real gem at heart
-
Researchers working in Germany and the UK have discovered that Nitrogen-Vacancy defects in diamond can be used to create a magnetometer capable of detecting the broadband magnetic signals generated by HDD write-heads. They've shown it possible at nano-meter resolution, to detect the static and oscillating fields associated with a write-head, a move that is expected to further shrink hard-drives since currently, the industry have no devices capable of 5-10nm resolution. Comes with diamonds, fricken' lasers and exciting colour-change technology.. Diamond magnetometer could help shrink computer hard drives - physicsworld.com[^]

OK, they can read data at extremely high densities. Can they also write it?
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack. --Winston Churchill

Or maybe it will just be a bunch of NAND flash chips, a DRAM, and a controller. :-\
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint. You like that? You go right on staring at it. I prefer looking at galaxies. -- Sarah Hoyt

Right now they don't know if they can do either. What they've done isn't to create a new read head, it was to invent a hardware debugger for smaller write heads. In a few years we'll probably find out if they've managed to make read/write heads work at that scale in lab. Currently they've been blocked by not being able to see what the prototype write heads were actually doing.

The most advanced 2D NAND chips currently have cells sizes of about 15-20 nanometers, and store 3 bits per cell. Using 3D technologies, it is likely that NAND chips will easily achieve a 2D density higher than 5 nanometers, assuming this hasn't been done already.

Just did some work on my youngest son's laptop. His hard disk is "fast", but it was so slow relative to my SSD I don't know why anyone botherss with spinning disks outside of big data storage.
