Abstract

Magnetic tape with Co-Cr/Ni-Fe multilayers is prepared by using a facing targets sputtering system and 10- mu m thick polymide sheet as a substrate. Read/write characteristics of this tape are investigated using a conventional video tape recorder equipped with a highly sensitive single-pole head. It is proven that even tape with a total thickness of magnetic layers of 0.33 mu m should be highly efficient in recording and reproducing performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
