Overburning question
Let me apologize if this topic has come up before. I am trying to burn an
audio CD which exceeds the specified capacity the disc will allow. I ran Nero CD Speed to determine how far I could overburn. Nero CD Speed reported that the maximum capacity of the disc is 83:21:26. The audio CD I want to burn is reported as 82:05:05. Because this figure is lower than the reported maximum capacity of the disc, I assumed it would be safe to overburn without complications. The burning process completed without any problems, and the CD plays fine (even the final track). My question concerns the lead-in and lead-out. I know what they are. I also know they require about 90 seconds of disc space. What I don't know is whether the reported maximum capacity of 83:21:26 includes the necessary space needed for the lead-in and lead-out. The reason I ask this is because when I take the difference between the size of the audio disc I want to burn and the reported maximum capacity, I get a figure of 1:16:21. If I am correct in assuming that these figures represent minutes, seconds, and frames, then I don't have enough space for either a lead-in or a lead-out. |

Subject: How much data can they hold? 650MB? 680MB? http://www.cdrfaq.org/faq07.html#S7-6 On a single-session disc, the overhead for lead-in and lead-out are not counted as part of the user data area, so nothing is "lost" until you go multisession. (Can you find out what happens to the "not counted" part when you do multisession?) |

What I don't know is whether the reported maximum capacity of 83:21:26 includes the necessary space needed for the lead-in and lead-out. Leadin and leadout (runin, runout) for a single session are not counted in the capacity of a disc. For a multisession (data) disc, each session after the first takes about 13 MB. Note that the quality of the burn beyond rated capacity is not assured any more than a disc of nominally 90-100 minutes will record well enough to be used for data. The fortunate aspect is that errors in the leadout will not be significant, nor would be some truncation of the leadout as long as you have a modern player. Mike -- http://www.mrichter.com/ |

Sorry to comment on my own post (bad form), but I tried some experiments and got equivocal results. The question is whether the leadout/runout is included in CDSpeed's measurement - and I'm not certain. My inclination is that it is not; my tests are consistent with CDSpeed measuring from the end of the leadin to the end of the recordable region (i.e., including leadout). However, some of the numbers seem suspiciously low, suggesting that it might have an allowance for leadout. Sorry, but I've no controlled master disc or indpendent measurement. My suggestion is to assume that it measures to the point where the spiral runs out. Then to be safe, leave 13 MB (1.3 minutes of audio) for a full leadout, less if you want to take a chance on your reader. (The leadin is definitely not part of the measurement.)
