Titre : Simulating the air bearing pressure and flying height in a humid environment Type de document : texte imprimé Auteurs : Shuyu Zhang, Auteur ; Brian Strom, Auteur ; Sung-Chang Lee, Auteur Année de publication : 2008 Article en page(s) : 4 p. Note générale : Tribology Langues : Anglais (eng) Mots-clés : Pressure  Temperature  Water  vapor  Bearings  Vapor  pressure  Force Résumé : For a hard disk drive operating in a humid environment, the water vapor in the slider’s air bearing is typically compressed beyond its saturation vapor pressure, causing the vapor to condense. Consequently, the air bearing pressure decreases and the slider’s flying attitude adjusts to balance the forces from the suspension. A method for calculating this air bearing response to humid air is presented. Using two air bearing designs, several test cases are analyzed to illustrate the air bearing response for various temperatures and humidity levels. The calculated flying heights agree with those measured in commercial hard disk drives.
