(09-09-2004) - A newly developed lubricant could improve the performance, capacity and longevity of hard drives used widely in computers, music players, video recorders and other devices, researchers say.
Lubricant coats and protects the polished disc surface that spins thousands of times per minute as data are magnetically recorded, retrieved and erased on the drive by a head that flies back and forth dozens of times per second.
But today's standard lubricant, called perfluoropolyethers, is reaching its limits as disc drives spin faster and hold more data. In some cases, centrifugal forces are causing the lubricant to ripple. In others, the material flies off the spinning disk.
