Sony’s PlayStation disc factory repurposed for optical microlenses by 2028

Sony’s PlayStation disc factory in Thalgau, Austria, is undergoing a major shift as the company transitions from disc manufacturing to producing optical microlenses. This decision, confirmed by Sony DADC president Dietmar Tanzer, comes as the demand for physical game discs declines significantly. The plant, which currently produces 600,000 discs daily, will only make 10% of that volume by 2028.

Transitioning from Disc Production to Microlenses

The Thalgau plant, Sony's last wholly owned disc manufacturing facility, has already begun retraining its 300 employees to focus on microlens production. This shift follows Sony's long-term strategy of winding down physical disc manufacturing, a process that has been in motion for several years.

In December 2024, reports indicated that the Thalgau facility had started working on microlenses, which are essential for various applications, including automotive technologies. According to Tanzer, “up to 60 micro-optics fit on one disc,” showcasing the factory's capability to pivot towards new technology.

Investment in New Technology

Sony has invested approximately €30 million into this transition, indicating a serious commitment to the future of optical microlenses. The company aims to begin mass production as early as next year, targeting industries that require advanced optical solutions.

Microlenses can be utilized in a variety of innovative applications, such as enhancing light projection in automotive indicators. Tanzer illustrated this with an example: “a car turn signal that is projected onto asphalt.” This new direction not only reflects changing consumer habits but also positions Sony to capitalize on emerging markets.

The End of an Era for Disc Manufacturing

The decline of physical disc production marks a significant shift in the gaming industry. Since 1983, Sony has produced over 26.4 billion discs, with the majority manufactured in Terre Haute, Indiana, before operations moved to Thalgau in 2022. The last U.S. plant was closed in 2011, further emphasizing the transition away from physical media.

As the gaming landscape evolves, Sony's decision to repurpose its disc factory highlights the company's adaptability in meeting new technological demands while facing the inevitable decline of physical gaming media.
