 Thin metal disk:

• The hard disk in an HDD can be replaced by a very thin titanium or stainless steel substrate that is 30 to 125 microns thick (0.0012 inch to 0.005 inch).

• The combination of centrifugal force and moderate bending rigidity operate to maintain the disk flat as it spins allowing recording heads to fly at very low spacing.  This is different than hard disk technology which uses thick disks (large bending rigidity) to achieve a flat spinning surface. 

• Recording film geometry, areal density and other components in the HDD remain unchanged.  

• Titanium and stainless steel are stable materials that would be compatible with future (HAMR and BPM) recording technologies and fabrication processes.
