Faster DiskDrives on the way thanks to new lubricant
I'm not sure where this paragraph came from myself Both qualities are important for lubricant design. A computer's hard drive is polished to a mirror finish to create as perfect a surface as possible on which to record, retrieve and erase thousands of hours' worth of data over its lifetime.

"Both qualities are important for lubricant design. A computer's hard drive is polished to a mirror finish to create as perfect a surface as possible on which to record, retrieve and erase thousands of hours' worth of data over its lifetime. A lubricant coating shields the disk from damage during contact with the head, which can fly back and forth across the disk dozens of times per second."
The last time I saw a head actually make contact with the media surface on an HD the platter was not in good shape and of course the drive was useless. This is called a head crash, typically the r/w heads fly across the surface of the drive on a cushion of air and at the high speeds of HD's now, 7200~15000 RPM a r/w head making contact would surely cause lots of damage
This aside it appears to be a good thing and of course using fluid-dynamic bearings helps out a lot too
