1 Tbits/in3映像データ記録用垂直磁気テープ装置への展望

Future trends for high density video data storage of 1 Tbits/in3 in multimedia service would be discussed in this paper. Magnetic tape With Co-Cr-Ta/Ni-Fe multilayer has been prepared by using facing targets sputtering system. Read/write characteristics of this tape has been investigated using conventional VTR. It has been proven that the tape should be highly efficient in high density recording of 1 Tbits/in3.
