12x wrote at 52x ... hmm how did that happen?

Vampyromaniac · Aug 11, 2003, 06:06 AM

I recently bought a Lite-On 52x24x52 CD-RW drive . . . still had some 80min TDK 12x CD-R's to finish using . . . and just now I accidentally left the recording speed at 52x . . . and recorded an audio CD (length 81:31) in 2.5 minutes

And I just listened to it . . . and it recorded perfectly!

Is this a freak occurence, or do people commonly record CD's faster than they're rated for?
If so, I sure didn't know you could do that

I've tried pretty much the same thing. Although I do have my CDRW (IOMagic 52x24x52x) set to autodetect the media rating. In some cases I'll see a 12 or 16 rated CDR record at 24 or slightly higher. Rarely, if ever, has one of those recorded at 52x.

Thats sort of like my PC100 ram I bought a while ago, it would go up to 143MHz, while the PC133 ram I replaced it with could only hit 140MHz.

Sometimes something is produced to an exceptionally high quality just due to random errors working in your favor.

Yup. Good media such as TDK is able to record at higher speeds than it is rated.

There's a software tool you can get for the Liteon, that will tell you what speed it will consider writing at.

As I understand it - that's determined by a media list in the firmware (media that it already has an optimum strategy for) or by power calibration and OPC results.

http://www.liteonit.com/english/engl...er.htm#utility
The SMARTBURN utility is the one.

With Smartburn enabled, the drive should burn at it's detected speed for the media (or lower if selected?)
You cannot EXCEED the smartburn speed limit, unless you disable smartburn!

It may also be useful to have (in Nero 5.5) the hack which shows realtime burn speed indication.

When you buy CD's the speed rating is how fast they have been tested at. Usually they can handle higher speeds then what is stated on the package. I have done this myself and actually notified the maker of the CD and told them how fast I was able to burn with their media. I did get a response from them thanking me and that they would look further into to it. I have also done this a burned some baaaad stuff.......lol

See the only problem is that when doing a data cd like that burning way over speed is that the sectors are burned like this : /--\ when infact that are suppose to look like this : |--| and on important backup of data it can play havok cause its harder for cd drive to read the media and can cause data curption

BiGBrOwNPimpsta · Aug 11, 2003, 09:17 PM

yea it happens i buy 48x cds and it does the same thing. I have the same burner I think or it might be LG im not sure. and then sometimes crappier cds write at 10x when it says 52x max haha

Judas · Aug 11, 2003, 11:50 PM

I never been able to record to TDK EVER..... and when i has, the auto detect has always been like 6x or 12x...no higher (rated cds are 32x or 44x).... I had some 4x sony's left and i burnt to them at 12x....and i bought some 32x sony's and burnt them at 44x...So far, the best cd rw/cd r are maxcells....

BWX · Aug 12, 2003, 12:28 AM

As you know Vamp, I have the same burner

, and I have done the same thing. I recorded full speed (52x) on media rated much slower (I think it was 24x). It worked fine. I actually spent a whole night testing the burner with different media and all of it recoerded at much higher speed than rated. If something is really important I slow it down to rated speed just to be safe.

Vampyromaniac · Aug 12, 2003, 04:03 AM

Sorry, guys. I must correct myself. I originally listened to the CD on my computer, and it was fine. But to day I listened to it on a small stereo, and the last two tracks were skipping

I made another copy at 12x (from the original wavs on my hard drive), and it plays fine everywhere now

I've read that it sometimes over-estimates the max speed, creating a bad copy.

Yep, and I'm lovin it!

It can also be that the media maker did not change the ATIP code from older media to newer media certified for higher speeds.

As I understand it, on CD-R media (unlike RW), the ATIP code does not specify the speed.

The only thing that can be relied on from an ATIP id, is the length.

Stampers may have been re-sold, so the media is not made by who you expect.
Stampers may be being used with a different dye formulation.

With a Liteon drive, it's also worth scanning the resulting burn with CDR-Doctor or K-Probe.

What you hope for, is a low C1 error profile, with a low average and maximum, and no serious peaks - and a ZERO C2 error profile.
