... Abstract As the Hard Disk Drive industry migrates from PMR to HAMR technology, it is important to understand differences in the measurement of contact detection between PMR vs. HAMR media. Compared to PMR media, HAMR media tends to be rougher and has a higher thermal conductance. Since some...

... slider lubricant thickness. The temperature rise of the disk surface tends to promote the lubricant transfer to the slider in a region close to the trailing edge. However, this effect may be locally suppressed by the laser-induced local thinning of the lubricant film on the disk. hard disk drive...
