Abstract :
Magnetic tape with Co-Cr/Ni-Fe multilayers is prepared by using a facing targets sputtering system and 10-μm 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 μm should be highly efficient in recording and reproducing performance
