Thin film tape media with multilayers by sputtering

Abstract

Magnetic tape with Co-Cr/Ni-Fe multilayer has been prepared by using facing targets sputtering system and 10 ,um thick polyimide sheet as a substrate. Reahrite characteristics of this tape have been investigated using conventional VTR equipped with highly sensitive single-pole head. It has been proven that even tape with total thickness of magnetic layers of 033 p m should be highly eMcient in recording and reproducing performance.
