  I think OP was referring to CDs, which AFAIK don't have DRM.

    My link is to the CD DRM!

      This is rather misleading. Standard CDs as sold had (and have) no DRM. The scheme you link to is intended to prevent further copies of CD-Rs but you can copy a CD you bought as often as you like.

        Unless the CD comes with a root kit that interferes with that copying. https://en.wikipedia.org/wiki/Sony_BMG_copy_protection_rootkit_scandal https://en.wikipedia.org/wiki/Sony_BMG_copy_protection_rootk...
