The 1990s marked a transformative era with the introduction of CD burners. As the prices for writable media and drives fell, consumers eagerly began duplicating games, creating custom mix CDs, and backing up their data on optical discs. It was a golden age for this technology.
Fast forward to today, and we’re witnessing a significant decline in the use of optical media. In light of decreasing consumer interest, Sony has announced plans to halt production of writable optical media. Let’s take a closer look at this development and what the future holds for writable optical discs.
Sony’s Optical Media End
Sony’s plant in Tagaze, Japan, was responsible for its optical disc manufacturing. The company has revealed that 250 out of 670 jobs will be lost due to the end of writable media production, affecting CD, DVD, and Blu-Ray lines.
However, it seems this decision won’t impact the production of pre-recorded pressed media in the short term. Japanese media reports indicate that the company will gradually cease production of optical disc storage media, including Blu-Ray products.
For now, you can still expect physical releases of music, games, and movies. Local stores remain stocked with DVDs and Blu-Rays, and you can still find albums from artists like Taylor Swift and Doja Cat on CD if you have a CD player in your car.
Major retailers continue to offer titles for gamers who prefer disc-drive versions of modern consoles. Yet, if you ask an average PC gamer when they last used an optical disc, they might respond, “What’s an optical disc?” That market has largely moved on.
The State of Discs
While Sony exits the industry, other manufacturers remain. The market has consolidated, with many brands now produced by a few companies. Notably, Taiyo Yuden, a pioneer in recordable CDs, left the market in 2015, followed by Mitsubishi and Verbatim. These companies were eventually acquired by Taiwanese firm CMC Magnetics, which produces discs rebranded as Memorex, Imation, HP, TDK, and others. The remaining major player is Ritek, which manufactures various CD-Rs, DVD-Rs, DVD+Rs, and BD-Rs and BD-REs.
You may wonder who is still using optical media today. Most consumer applications have dwindled significantly. Few people burn CDs for their cars anymore, given the prevalence of aux ports, Bluetooth, and USB connections. Similarly, transferring data via sneakernet is now more easily accomplished with flash drives or larger portable hard drives.
However, optical media continues to be an excellent solution for long-term archival storage—if you choose the right discs. While cheap CD-Rs and DVD-Rs are not ideal, M-Discs are specifically designed for this purpose. Available in DVD and Blu-Ray formats, they can reportedly store data for “up to 1000 years.” This longevity is achieved through a stable inorganic glassy carbon layer that stores the data, which is much more durable than the organic layers in typical writable media. It’s believed this material could last up to 10,000 years under optimal conditions, though the polycarbonate layer on top is expected to survive for only about 1000 years.
When it comes to high-capacity cold storage, optical media remains a strong contender. While tapes can compete on cost and density, they generally don’t match the longevity of optical media. For example, an M-Disc might last 100 to 1000 years, whereas a tape may only last about 30 years. Recent users of optical media include members of Reddit’s r/DataHoarder community and various state government agencies. For those needing to preserve large amounts of data for extended periods, optical media may still be appealing.
There are also hopes that optical media could see a resurgence in the future. Researchers in Shanghai have recently discovered a method to create an optical disc that could store around 200 TB by utilizing a nanoscale three-dimensional structure to achieve unprecedented storage densities. If successful, these discs could compete with hard drives for certain applications. However, it’s still early in the research phase, and challenges like write speed remain—having a 200 TB disc won’t be useful if it takes too long to read and write data.
While optical media may no longer be the mainstream favorite it once was, it’s far from dead. And if vinyl and cassettes can make a comeback, who knows where the CD market will stand in ten years? Human culture is unpredictable and fascinating.
