Hard Disk Drive Technology, HAMR, and Dielectric Resonators

Abstract: Magnetic hard disk drives (HDD) continue to be a dominant technology for information storage. Notwithstanding developments in other information storage technologies HDDs are unlikely to be displaced any time soon for reasons I will discuss in this presentation. I will also discuss the physical limitations faced by magnetic recording technologies and how these limitations are being addressed, notably, through the development of Heat Assisted Magnetic Recording (HAMR). HAMR is developing with greater certainty into a commercially viable technology. A key element in making HAMR a success is a long-lived system that can deliver energy into the nanoscale areas on a hard disk required for recording at and beyond 1 Tbit/inch2. I will present some of our work at developing a dielectric, rather than metal resonator, structure along with a nanoscale energy delivery system and discuss why we believe this approach has key advantages in a HAMR recording system.
