Stiction

Hi I have several friends that worked at Seagate when they had problems of stiction. It was not a lubricant problem. It was caused by the surfaces being too smooth. When to really smooth surfaces sit together for a long time, the air is squeezed out. Once the surfaces really touch, there is a thing called molecular adhesion. Anyone that has worked with guage blocks is familair with this. Seagate fixed the problem by roughing the surfaces enough so that they didn't quite sqeeze out enough air to adhere. The surfaces are lubed but not with petrolium greases so they don't break down to tars. As I recall, they used some type of synthetic oil and only in tiny amounts. It was just to keep the surfaces apart while it spun up. After that, the head was flying and no longer made contact.
