Abstract
We investigated the influence of the vibration characteristics of a head/disk system in contact recording. The frequency response function (FRF) and Q factor were used to analyze the vibration of the head-disk interface motion in sliding contact tests. The effect of the natural frequencies of the various disks is examined. The Q factor, obtained from the FRF of the vibration of the head-disk interface motion, is related to the durability in sliding contact tests.
