MIT boffin: Salted disks hold SIX TIMES more data • The Register

Disk drive technology has gone through revolutions and evolution at different times in its history of manufacture. From the introduction of the original IBM RAMAC to the newest 4TByte SATA hard drive progress has always been made towards higher densities at the least and higher speed access at the most. Now conventional magnetic recording techniques are hitting a plateau of density. The best we might be able to achieve is 1TByte per disk platter. But wait, there’s still hope, and that hope may be in Bit Patterned Media and there may be a cheap way to do it. Read On:
