The performances of isotropic thin film texturing on glass substrates
have been investigated. Samples with various surface topographies have
been prepared to measure touch-down height(TDH), read/write(R/W) perf
ormance and friction coeffient with ahead slider. TDH correlates fairl
y well to the Peak to Average height of the surface profile measured u
sing AFM. R/W performance is almost the same for the various textures
investigated suggesting that the flying height of the slider correlate
s well with the average height of the textured surface. The initial fr
iction coefficient increases with the density of microbumps.
