Description

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.

How Gen AI Is Reshaping Video Production — with Adobe’s David Helmly and Andy Edwards

Host Paul Langston sits down with David Helmly and Andy Edwards of Adobe for a conversation on how generative AI tools are transforming creative production workflows—and what that means for the data infrastructure behind them.  With a combined 60+ years of broadcast and creative software experience, Dave and Andy argue that every major technology shift has expanded creative possibility, and that AI is no different. The conversation outlines what the use of generative tools looks like in practice, beginning from a single image or low-res video before being upscaled, tagged with media intelligence data and stored alongside every ideation file needed to prove authorship. What started as kilobytes becomes a cascade—and none of it can be discarded.  You'll gain insights into:  * Why generative AI inverts traditional production workflows and accelerates data growth   * How Adobe's content authenticity framework tracks AI usage across assets  * How Adobe lets enterprise customers train generative AI model on exclusive IP  * Why nothing in the production chain gets thrown away   * What agentic AI looks like inside a creative workflow     Chapters:  [01:38] Adobe's Seismic AI Shift  [03:02] How Broadcasters Are Using AI  [05:14] How Adobe Improves Products for its Customers  [08:08] The Video Data Explosion  [11:32] Provenance & Media Intelligence  [13:53] Creative Control with Adobe Firefly  [19:11] AI-Assisted Editing  [21:44] How Adobe Protects Content Authenticity  [24:19] Agentic AI for Video Production  [31:10] Advice for Creators Navigating AI  [33:41] Lightning Round Q&A    About the Guests:  David Helmly Sr. [https://www.linkedin.com/in/dhelmly/] is Director of Professional Video and Audio at Adobe [http://www.adobe.com/], where he leads technical relationships with broadcasters, studios, and creative professionals across the video and audio production ecosystem.  Andy Edwards [https://www.linkedin.com/in/andy-edwards-post-production/] is a Strategic Business Developer at Adobe [http://www.adobe.com/], focused on helping broadcast and media customers get the most out of Adobe's professional video tools.    About Seagate:  Seagate is a leader in mass-capacity data storage.
