Near-field Imaging of Nanoantennas Inside Integrated Heat-assisted Magnetic Recording (HAMR) Devices


Scientific Achievement

A team of Foundry staff and industry users have visualized the behavior of nanoantennas inside heat-assisted magnetic recording (HAMR) memory devices using top-down and bottom-up approaches.

Significance and Impact

This is the first time that nanoantenna behavior has been characterized on an integrated device using these methods. The results will enable next generation hard disk drives to move from development to commercialization.
