WD 18TB and 20 TB

WD has some new drives. How are they cramming more data per platter diks in there? It's not clear if they use the WHAMR or something.

?? The actual NAME of the product contains the recording technology ??

18TB CMR - Conventional Magnetic Recording
20TB SMR - Shingled Magnetic Recording

?? Also super clear in the linked datasheets on the technology being used ??

"Western Digital is combining a new nine-disk platform and energy-assisted recording."
Of course we have already discussed the CMR vs. SMR recording technology, but what is the energy assist technology? I doubt it is like a Chevy.
