Do you prefer CD-R or CD-RW for music? (sopuli.xyz)

For those who use CDs for music, which writable CD type do you use, and why?

Main differences:

  • CD-R can only be written once
  • CD-RW is more expensive

CD-R is written in an organic-dye, which deteriorates ( I've read the AZO chemistry is more enduring )

CD-RW is written in the crystallization of a metal layer.

CD-RW is permanent record, unless you heat them, or blank them, or overwrite/rewrite them: chemical-deterioration isn't a problem.

I learned this with backups, many many years ago.

I've no idea if DVD-RW discs also are recorded in a eutectic metal layer, but they've multiple record-layers ( 2? ), and I'm don't know how you can make a eutectic-metal layer that is transparent-enough to get through/past it to write the next layer,

so I've no idea how permanent DVD-RW's are.

I've lost data on the -R technology.

I've never lost data on the CD-RW technology.
