I would also add that when using optical discs for backup, M-Discs are probably preferable over conventional dye-based discs.

  Wow, do they work with conventional recorders?

    No, but they work with conventional readers. You need a special laser to do the physical etching that they're doing.

    Only if they say "M-Disc" on it. Many consumer recorders, especially if made by LG, support writing to these discs.
