  • Abstract
    A set of Co-CoO metal evaporated tapes were prepared with various O2 flow rates. Recording tests determined the optimum flow rate and a second set of tapes were prepared at that flow rate with thickness from 33 nm to 103 nm. For thinner tapes the recording carrier to noise ratio is increased while the optimum recording current reduced. Remanence coercivity at 2 ns is about 30% higher than at 100 s and is independent of the thickness. Thermal stability is excellent down to the thinnest tape where KV/kT is still 170
