Z-Tetraol Reflow versus Trough Width in Heat-Assisted Magnetic Recording.

Lubricant reflow versus trough width for 10 - 13 Å Z-Tetraol films is characterized by numerical simulation using the experimentally determined thickness-dependent diffusion equation. Lubricant reflow is simulated in a single trough of 10 – 13 Å depth as a function of trough width from 50 nm to 50 µm. The results of the numerical simulations indicate that trough recovery by reflow decreases with increasing trough width. The numerical simulations are compared to experimental reflow where such data are available in the literature
