Sony is repurposing its Thalgau plant from disc production to microlens manufacturing. The facility, once the sole remaining wholly owned disc-making hub for Sony, now faces a future without discs. Production of PlayStation discs will drop drastically by 2028, forcing a retraining program for all 300 employees.
The transition isn’t sudden; in December 2024, Sony was already experimenting with microlenses. This €30 million investment marks the beginning of mass production that could start next year, aimed at automakers and emerging tech applications like headsets and car signals.
This move underscores a broader trend: as disc technology wanes, new optics take center stage. The Thalgau plant’s history—from Indiana to Thalgau—illustrates this shift over decades, ending with a final repurposing that is both economically pragmatic and technologically forward-thinking.
Sony has produced an astounding 26.4 billion discs since its inception, mostly in Terre Haute, Indiana, until the plant’s closure in 2011. Now, it looks to the future with microlenses, bending light where once it bent discs.
