Abstract
Both frequency and time domain analysis of glide signals from a PZT glide-slider flying over a laser zone textured thin film disk media was used to determine the many sources of slider excitation. The glide signal strength was particularly dependent on the velocity-induced laser bump excitation and the effect of the air-bearing stiffness over the laser zone. Peaks were found on the glide-avalanche curves that were traced to both the laser-bump induced resonance of the slider and the effect of the air-bearing over a laser textured zone. Laser bump excitation far from the slider's natural vibrational modes was found to reduce the power transfer to the slider through the air-bearing.
