Abstract :
When a thin liquid film of contamination is present between a head and disk, surface tension and viscous forces can increase the force that resists disk motion. A striction-force model is proposed. The model shows fairly good agreement with the data. Both the model and the data show that stiction forces increase with decreasing surface roughness and increasing contamination thickness
