Mozaic and the Future of Mass-Capacity Storage – with Stephanie Hernandez

In this episode of The Data Movement, host Paul Langston sits down with Stephanie Hernandez, Senior Engineering Director at Seagate, to explore Mozaic—Seagate’s breakthrough HAMR (Heat-Assisted Magnetic Recording) technology platform—and how it’s redefining what’s possible in mass-capacity data storage. Stephanie shares her 15-year journey from magnetic recording researcher to leading future HAMR innovations, explaining how atomic-scale engineering, lasers, and advanced materials like iron platinum are enabling 30TB, 40TB, and soon 100TB-class drives—all within the same familiar 3.5-inch form factor. From overcoming the superparamagnetic limit to scaling production to millions of drives for hyperscale data centers, this conversation reveals the extraordinary science, precision, and vision powering the infrastructure behind the world’s exploding data demand.   Time Stamps  00:00:00 – The Power of Data and Introducing Mosaic 00:01:00 – Stephanie’s 15-Year Journey at Seagate 00:03:30 – The Rise of HAMR and Industry Skepticism 00:08:30 – Understanding the Superparamagnetic Limit 00:10:50 – Grain Size, Signal-to-Noise, and Scaling Challenges 00:12:30 – The Core Innovations Behind HAMR 00:16:00 – Atomic-Scale Precision and Laser-Assisted Recording 00:23:30 – From Research Concept to Mass Production 00:26:30 – Why Capacity Growth Matters to the World 00:27:50 – Hyperscalers, Form Factor, and Fleet Economics 00:31:00 – Driving Aerial Density Toward 10TB per Disc 00:33:30 – Multisensor and Advanced Recording Technologies 00:40:00 – Beyond HAMR: Future Media and Architectures  00:43:00 – The Hidden Innovation Inside the Hard Drive   About Stephanie Hernandez     Dr. Stephanie Hernandez is Senior Engineering Director at Seagate Technology, where she leads advanced research and development for next-generation data storage technologies, including Heat-Assisted Magnetic Recording (HAMR) and other cutting-edge media and memory systems.
