“…The tribological performance of ME tape, however, is problematic compared to MP tape, especially Fig. 13 Minimum spacing c versus tape speed for a dimensionless tape tension of T/(p a R) = 0.1 at low-tape speeds, where surface contact occurs between the tape and the guide surface [6,20,21]. Dimpled guide surfaces create a higher air bearing pressure compared to smooth guides and thus, increase the flying height at low speeds.…”
