The dynamic coercivity of longitudinal magnetic recording media has been investigated using a spin-stand. Improvement of the media orientation ratio (O.R.) or the in-plane alignment of the anisotropy axes not only results in the improvement of thermal stability at storage times but also in a reduction of the difference between the coercivity at high data rates (<10 ns) and at semi-dc conditions (/spl ges/1 s). Comparison of remanence curves at 1 s and 14.3 ns indicate that the optimum writing current does not increase as significantly as the coercivity.
