HIGH DENSITY DIGITAL RECORDING PERFORMANCE OF METAL EVAPORATED TAPE

Abstract

This study deals with the dependence of a byte error rate on the S/N ratio for a metal powder tape (MP) and a metal evaporated tape (ME). We found that the error rate of the ME was smaller than that of the MP for the same S/N ratio. The byte error rate between 10^<-6> and 10^<-7> was obtained using the ME and a sendust sputtered head with 5μm track width of the 0.7μm recording wavelength.
