| However if you’ve tried to read those cd-rw after 20-30 years, they would most likely be corrupted. Factory stampted cds are better in this regard |

| Factory stamps are still not immune to bit rot, even when stored in ideal conditions. |

| Is there a reason why or is it just the quality of the materials? |

CD-R = Pits are still physical, but they are on a die layer that can fade. Some discs are more resilient (blue, gold) than others (cyan).
CD-RW = Pits are (mostly) bistable for practical purposes, but will degrade to a neutral state on a long-term basis. | |

They hold up much better if stored in a dark place. A spindle on a shelf that sees sunlight is the worst case and they can become unreadable in years. | | | |
