Abstract :
The effect of relative humidity on the friction and wear of thin-film media with different lubricants has been studied. The presence of physically adsorbed water vapor at elevated humidity increased the take-off velocity leading to more head/disk interacting. In addition, chemical interactions between water vapor and lubricant with diol (-OH) end groups were seen at humidities above 65%
