The Application of High Hc Cobalt-Iron Oxide Tape for Digital Video Recording

The 4:2:2 component recording system (Type D-1) records signals at a rate of over 200 Mb/sec with a shortest recording wavelength of only 0.9 um. — Low error rates (in the order of 10^–6 to 10^–7) can be obtained if a tape formulation can be developed with a high output and low noise characteristics optimized to record at these wavelengths. As the D–1 DVTR can only use ferrite video heads, a high coercivity cobalt oxide tape was developed to meet the needs of the format. — The paper discusses why such a formulation was chosen and contrasts how the D–1 tape performs against other media when evaluated for the 4:2:2 standard.
