Sony's Clever but Flawed PlayStation Copy Protection--And How They Might Have Fixed It
Technology Connections・2 minutes read
Sony implemented copy protection measures for the PlayStation by adding a unique wobble to discs during mastering, making it challenging for CD burners to replicate. Despite the success of CDs for game data storage, the decision to stick with the standard size was driven by the need for quick and cost-effective game manufacturing, as creating a larger disc format would have been impractical.
Insights
- Sony implemented unique copy protection measures for the PlayStation, such as adding a specific wobble to discs during mastering, to deter piracy despite facing challenges with CD copying.
- The decision to maintain the standard CD size for PlayStation games, rather than opting for a larger disc format that would prevent easy duplication, was driven by cost-effectiveness and practicality, highlighting the balance between piracy prevention and manufacturing efficiency in the gaming industry.

PlayStation Copy Protection: Challenges and Solutions
- Sony faced a challenge with the PlayStation due to the ease of copying CDs, prompting them to implement copy protection measures.
- The PlayStation could detect counterfeit discs despite having identical data due to a unique feature during mastering.
- Mod chips and disc swapping were common methods to bypass the copy protection on PlayStation discs.
- The PlayStation's success was attributed to its use of CDs for game data storage, despite drawbacks like slow load times.
- Sony's copy protection involved adding a specific wobble to the disc during mastering, which ordinary CD drives would ignore.
- CD burners look for a wobble on CD-Rs for tracking and writing purposes, making it difficult to replicate the PlayStation disc's wobble.
- Sony's copy protection was easily circumvented by exploiting the console's tolerance for damaged discs or using modchips.
- The PlayStation's copy protection was only checked at bootup, allowing for disc swapping with burned copies.
- A design quirk of the PlayStation's larger CD area raised the possibility of discs containing data beyond a standard CD's range.
- Sony could have made PlayStation discs larger, increasing data capacity and making copying nearly impossible by extending the CD drive's rails.

PlayStation Disc Size Choice Balances Cost, Security
- A larger PlayStation disc size would have prevented it from fitting into standard CD burners, making duplication difficult due to the unique size. This would have made copying games impossible without the console detecting it, as no CD drives were available for such large discs, deterring piracy.
- Sony's decision to stick with the standard CD size for PlayStation games was driven by the need for quick and cost-effective game manufacturing. Creating a new, larger disc format would have required significant investment in new machinery and case designs, making it impractical despite the potential piracy prevention benefits.
