Sony pivots its final disc plant toward high-tech optics

Dietmar Tanzer, president of Sony DADC, confirmed that the Thalgau plant currently churns out 600,000 discs daily, half of which are dedicated to PlayStation consoles. With production volumes slated to drop by 90 percent by 2028, the facility has already begun integrating equipment for micro-optics. These components, which utilize the same disc-based manufacturing processes to bend light, are expected to enter mass production as early as next year. Potential applications include advanced automotive lighting, such as turn signals projected directly onto the road surface.

This transition marks the conclusion of a decades-long decline in physical media manufacturing for the company. After closing its New Jersey facility in 2011 and moving Indiana-based operations to Austria in 2022, Sony has steadily offloaded its legacy infrastructure. The Indiana plant, which produced 23 billion of the company’s 26.4 billion total discs, now serves the automotive industry, signaling a broader shift in Sony's industrial strategy. While the move away from gaming discs has faced consumer pushback, the infrastructure is already being repurposed for a market that requires precision optics rather than entertainment software.
