We report on a method used to characterize disk drive chemical outgassing and results on chemical outgassing dynamics. Chemical outgassing results indicate that the drive outgassing rate increases with drive temperature and the rate is exponentially dependent upon temperature (Arrenhius activation energy : 15 kcal/mole). The outgassing rate of a functional disk drive decreases, in a dual exponential fashion, with drive operation time and is discussed in terms of outgassing and offgassing phenomena. The applied value of determining outgassing properties of operational disk drives is it provides a means to correlate chemical characteristics with disk drive performance.
