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

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