“…Via numerical simulations, it has been discovered that this favorable effect exists not only for patterns with convex islands but also for patterns with rectangular islands (Fig. 2.8c) [52]. This is attributed to the combined effect of patterning and periodicity.…”

“…Therefore, exactly as in the case of a convex mirror, one could use a SUL with a convex boundary to move the image closer to the ''mirror's'' (SUL's) boundary with the recording layer [51]. To illustrate this effect, a diagram comparing the positions of the images in the two cases is shown in Figure 6.8b.…”

“…The SUL is known to conduct the magnetic flux generated by the recording head very readily, thus enhancing the magnetic writing field from the recording head. [15][16][17][18] This helps to increase the effective recording field in the system.…”

Magnetic write field is a critical factor in determining the quality of the magnetic write transitions, which determine the linear density (LD) limit in heat-assisted magnetic recording (HAMR). We introduce a reversed DC band approach as a simple, no extra-hardware-Required technique in a spin-stand to assess the magnetic write field ( ) contributions, independently in an HAMR system. Heads with different distances between near-field transducer and writer pole, and media with and without soft magnetic under layer were characterized. The estimated result strongly correlates with LD and signal-to-noise ratio, which agrees with previous modeling studies. These results give insight into the head/component required to optimize the HAMR’s system performance. The technique provides qualitative ranking of magnetic write fields and recording temperature, as well as laser operating current at Curie temperature for head/component designs.
