Investigations of the taper contamination on the flying characteristics ofa slider

The influence of taper contamination on the static and dynamic characterist ics of a slider is studied in detail. Two models of taper contamination are investigated. The investigation studies the effect of skew angle, the numb er of tapers contaminated, and the amount of contaminants on the flying cha racteristics on the slider. Calculations show that irrespective of the mode ls considered and the number of tapers contaminated, the static and dynamic characteristics of the slider show little change even with a large amount of contaminants. However, once the amount of contaminant exceeds a certain limit, the flying altitude of the slider is degraded and can cause head-dis k interaction. When the skew angle is large, it may either ameliorate or de teriorate the flying characteristics of the slider depending on the slider attitude when the transverse airflow passes through it.
