A study of the mechanical and magnetic performance of metal evaporated tape

The influence of operating and design parameters on the magnetic tape/guide friction coefficient

“…Hempstock and Sullivan [24] studied the durability and signal performance of ME and MP tapes and concluded that MP tape exhibits far greater durability than ME tape. In another study Hempstock and Sullivan [25] identified the mechanical failure mechanism of ME tape as a form of delamination wear. Bijker et al [26] discussed the use of wear protective coatings such as diamond like carbon (DLC) and a so-called super protective layer (SPL) to potentially improve the wear characteristics of ME tape.…”

Enhancing tribological performance of the magnetic tape/guide interface by laser surface texturing

“…The tribological performance and reliability of ME tape is inferior compared to MP tape [26][27][28]. Wear protective coatings such as diamond like carbon or a so-called super protective layer have been used to improve the wear characteristics of ME tape [29].…”

A Model for Magnetic Tape/Guide Friction Reduction by Laser Surface Texturing

“…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.…”
