Which media format holds more information?

Explanation:
Storage capacity depends on how densely data can be stored on the media and how the format encodes that data. Blu-ray uses a shorter-wavelength laser and higher storage density, plus advanced encoding, so it can hold far more data per disc than the other formats. A typical Blu-ray disc stores about 25 GB per layer (50 GB for two layers), which is much more than a DVD (around 4.7 GB) or a CD-ROM (about 0.7 GB). VHS is an analog tape format and isn’t designed for digital storage, so it carries far less usable data information for digital content. So Blu-ray holds more information overall.
