Abstract :
A magnetic tape with a 65-nm-thick magnetic layer containing fine barium-ferrite particles was produced using an advanced precision coating process. Using a giant magneto-resistive head on a drum tester, a signal-to-noise ratio of 23.5 dB was achieved at a linear density of 200 kfci, indicating the feasibility of approximately 7 Gb/in2 recording density
