Abstract
The coercivity and perpendicular orientation effects on duplication performance for the Ba-ferrite slave tape are studied by means of a DAT (digital audio tape) performance measurement on DAT recorders and anhysteretic magnetization process measurement for the slave tapes. Environmental stability for the duplicated Ba-ferrite tapes is also described. It is shown that perpendicularly oriented Ba-ferrite slave tapes, with relatively low coercivity values of around 600-700 Oe, enable a high-speed magnetic contact duplication of 76 kFRPI DAT signals to be practical. A sufficiently low error rate and high environmental stability are demonstrated for the Ba-ferrite tapes. The magnetization mechanism involved in the duplication process is analyzed in terms of anhysteretic remanent magnetization. >
