Is there a limit to how much can be stored on a single disc?

Yes, there is a limit to how much data can be stored on a single disc, which depends on the type of disc and its technology. For example, standard DVDs can hold about 4.7 GB of data, while Blu-ray discs can store up to 25 GB for single-layer and 50 GB for dual-layer versions. Advanced technologies, like BDXL, can increase capacity further, but practical limits exist due to physical and material constraints. Additionally, as technology progresses, newer disc formats may allow for greater storage capacities.
