A former chairman of Sony Interactive Entertainment USA—Shawn Layden—has shared his views regarding current and future PlayStation product landscapes. In an interview conducted by podcaster Reece Reilly (of KIWI TALKZ), the American businessman was asked about Microsoft's recent-ish release of all-digital Xbox home consoles. Layden believes that Sony will not copy its main rival's homework—the heavily rumored "PlayStation 6" could launch in two forms: with an optical drive, or without. The ex-SIE boss commented about a potential disc-less future platform: "I don't think Sony can get away with it now...I think Xbox has had more success in pursuing that strategy, but Xbox is really most successful in their business in a clutch of countries: the U.S., Canada, UK, Ireland, Australia, New Zealand, South Africa. Coincidentally enough—all English-speaking countries."

The current day PlayStation 5 family—consisting of standard, slim, and Pro models—is this generation's market leader; having established a huge international userbase (roughly 65 million units, back in September 2024). Layden cites these numbers as a guideline for the makeup of a new-gen model: "Sony, which is the number one platform in probably 170 countries around the world, has an obligation or a responsibility to say: 'If we go discless, how much of my market is not able to make that jump?' Can users in rural Italy get a decent connection to enjoy games?" He thinks that his former colleagues are making very careful considerations, given the complicated nature of catering to a diverse audience: "which part of your market will be damaged by going to disc-less market? I'm sure they're doing their research on it. And there will be a tipping point, where there's some percentage where you can say, 'Okay that's fine, we can turn our back on that part of the market.' But Sony's market is globally so huge, I think it would be hard for them to go fully disc-less, even with the next generation."

The University of Shanghai for Science and Technology (USST), Peking University and the Shanghai Institute of Optics and Fine Mechanics (SIOM) are collaborating on new Optical Data Storage (ODS) technologies—a recently published paper reveals that scientists are attempting to create 3D nanoscale optical disk memory that breaks into petabit capacities. Society (as a whole) has an ever-growing data demand—this requires the development of improved high-capacity storage technologies—the R&D teams believe that ODS presents a viable alternative route to traditional present day solutions: "data centers based on major storage technologies such as semiconductor flash devices and hard disk drives have high energy burdens, high operation costs and short lifespans."

The proposed ODS format could be a "promising solution for cost-effective long-term archival data storage." The researchers note that current (e.g Blu-ray) and previous generation ODS technologies have been: "limited by low capacities and the challenge of increasing areal density." In order to get ODS up to petabit capacity levels, several innovations are required—the Nature.com abstract stated: "extending the planar recording architecture to three dimensions with hundreds of layers, meanwhile breaking the optical diffraction limit barrier of the recorded spots. We develop an optical recording medium based on a photoresist film doped with aggregation-induced emission dye, which can be optically stimulated by femtosecond laser beams. This film is highly transparent and uniform, and the aggregation-induced emission phenomenon provides the storage mechanism. It can also be inhibited by another deactivating beam, resulting in a recording spot with a super-resolution scale." The novel optical storage medium relies on dye-doped photoresist (DDPR) with aggregation-induced emission luminogens (AIE-DDPR)—a 515 nm femtosecond Gaussian laser beam takes care of optical writing tasks, while a doughnut-shaped 639 nm continuous wave laser beam is tasked with retrieval. A 480 nm pulsed laser and a 592 nm continuous wave laser work in tandem to read data.

Sony Interactive Entertainment has filed a patent that is now viewable to the public - as spotted by SegmentNext today - and the newly registered device could be designed to function as part of an updated variant of the PlayStation 5 home video game console. The 2020-era patent document showcases a type of detachable optical disc drive, and industry experts reckon that this mountable media reading device is destined, following past rumors, to feature in an upcoming PlayStation 5 hardware revision.

No reference is made to Sony's popular gaming console within the patent filing, but it is highly likely that the new optical drive will factor into the refreshed console's modular makeup - its overall shape shares design aesthetics with the PS5. Sony currently offers customers two variants of the PlayStation 5 - the more advanced model is fitted with an internal 4K Blu-Ray compatible disc drive, while the other one functions as a purely digital download device. The modular revamp is expected to arrive later this year, in a more compact form factor that industry insiders have called "D chassis" - it is not known whether this variant will outright replace the older models. A more powerful PlayStation 5 "Pro" model is expected to arrive after the modular redesign, with tipsters pointing to a launch window in mid-to-late 2024.
