Re: Reason #3 is the best reason
i'm pretty sure your right
It applies to the software layout of the disc as well things such as pre emphasis, playback gaps and a few other things |

The reason Philips says DRM enabled disks cannot be considered compact disk audio is because of exactly what you said. Red Book standards are in place to make sure the CDs conform to specifications that make them play on every CD player built to those specifications. No so with many DRM technologies. A DRM disk will not play on all CD readers, thus not conforming to Red Book standards. Pretty cool decision on Philips part if you ask me. |

The storage format specs for audio (16 bit resolution and 44.1kHz sample rate) is there for a universal compatible play back in standard cd players. Much like 45s (45 rpm) and Lps (33.3 rpm), in the old days of vinyl records, were the speed standards. If you played it faster or slower it would sound way different. If I made my audio cds at a 24 bit res and 96 kHz sample (what I record at and a better sounding,lower noise floor recording), they would not only not play in a regular cd player but would not have enough space on a regular cd. The files have to be dithered down to 16-44.1.Hence the red book audio storage specification standard. There are no stipulations as to what kind of data is written on the disc, just as long as the audio plays in a regular audio cd player and the tracks can be located. |

Red Book is an audio specification standard as well as the physical standards. Not only does the Red Book standard make specifications for the dimensions of the compact disk it also specifies the bit rate for the content (1411 Kbps), the parameters for disk readers (including error correction), modulation system and subcode channels (anybody remember CD+G?). The Red Book standard stipulates a CD layer at 1.2mm, while DRM enabled CD's have a thinner layer. That and the fact Red Book specifies no more than a bit allocated for anti-copying and you have a non-Red Book disk.
Interestingly enough since those DualDisk albums also have thinner layer (.9mm). As such they cannot be considered CD's either. |

Red book standards are manufacturing standards, not content standards. |

Those disks cannot be classified as CD (not permitted to bear the trademarked Compact Disc Digital Audio logo) per Phillips because audio disks with DRM do not conform to the Red Book specification for CDs. |

said by TKJunkMail  :said by nixen :said by TKJunkMail :Assuming that the facts are correct that 99% of CD's for sale are really DRM free, then that does make one wonder why downloaded copies aren't also DRM free. EVERY CD (music, not data-only) ever sold has DRM-free content. They had/have to in order to play in CD players. NO, that is not accurate. If the CD was used on a PC , some did have DRM software included on the CD. Sure they could be heard on a plain old vanilla CD player, but they couldn't be ripped to a PC without the DRM coming into play. Remember the SONY rootkit fiasco. /sigh
Really, genius-boy? So, you're saying that those hybrid/"enhanced" music CDs, playable in "vanilla" CD players, had no non-DRMed data on them?
And, yes, you most definitely COULD rip them on a PC without the DRM coming into play. All you had to do is disable the auto-run feature. The CD tracks were still available as rippable data separate from the "enhanced" content.
The Sony "rootkit fiasco" came from people allowing the code to run on their systems (either accidentally or intentionally). While Sony's to be condemned for victimizing the hapless, users need to take a bit of responsibility for what they allow to run or be installed on their systems.
