Sony’s last remaining disc manufacturing plant, located in Thalgau, Austria, is being repurposed to produce optical microlenses, as the company phases out physical media production. Dietmar Tanzer, president of Sony DADC, told ORF Salzburg that the plant currently produces 600,000 discs daily, half of which are for PlayStation, but expects that volume to drop to just 10 percent by 2028. To adapt, the company plans to retrain all 300 employees for microlens production, a shift already underway with a €30 million investment.
The Thalgau facility is not only Sony’s sole wholly owned disc plant but also the headquarters of its disc-making division. Sony previously operated disc plants in the United States, including Terre Haute, Indiana, and later New Jersey, but closed the latter in 2011 and consolidated all manufacturing to Thalgau in 2022. Today, the Indiana facility serves automakers with packaging and assembly services, highlighting Sony’s gradual move away from disc production.
According to Sony DADC’s website, the company has produced over 26.4 billion discs to date, with 23 billion manufactured between 1983 and 2022 in Terre Haute. However, declining demand for physical media, particularly for video games, has driven this strategic pivot. A behind-the-scenes video from December 2024 showed the Thalgau plant already working on microlenses, which are created using disc-like manufacturing processes.
Microlenses have applications in emerging technologies such as headsets and automotive lighting. The head of Sony’s micro optics division provided an example: a car turn signal projected onto asphalt. This shift positions Sony to cater to the automotive industry, leveraging existing expertise in precision optics.
The decision to repurpose the disc plant was not made hastily; Sony has been winding down disc manufacturing for decades. Despite predictable backlash from physical media enthusiasts, the company is unlikely to reverse course. With digital distribution dominating gaming and entertainment, the transition represents a final step in Sony’s evolution away from discs.
Mass production of microlenses may begin as early as next year, according to ORF Salzburg. This move signals Sony’s commitment to diversifying into photonics and optics, aligning with broader industry trends toward miniaturization and advanced sensing. The retraining of 300 workers ensures that the Thalgau plant remains operational, albeit with a new focus.
