optimal cd burner speed for master CD?

A lot do burn at 1X, but also up to 16X depending on their burner and media and system. Depends on what gets you the best results.

I've now tested a Plextor SCSI burner at different speed's with different media.
Some media is best at 1x and some i found did best at 4x.
I have a disk burn test in my Sequoia and (correct me if I'm wrong) what it does is comparing the burned material to the original soundfile.

It was very clear what the media liked best, when it was a little too slow or fast the burned disc got a lot of errors.

What media are you using Michael and others...? and are you making DDP or Audio CD's to go to the plant?

Best Regards,
Henrik

Right now i'm using TDK media, so far it's very consistent. I've tried others but it seemed to very from batch to batch. I don't know how your system compares, but it's nice that it does though. I now send out CD-R's to the plant but I'm really wanting to get a SonicHD system. I would like to stay on Mac and i've been told by sonic that I can have both sonic and protools cards in the same system. I have an exabyte 8505 drive and would like to send out DDP's but unless you have sonic or a really old version of Masterlist, there aren't any other options that I know of. if you have a plextor premium drive, they have software now that anaylzes the error rates on you CD. Not as indepth as a stand alone but still great to have none the less.

We use Taiyo Yuden CDR-80 and have no problems with them. We normally burn at 4 X and they are virtually error free. We use nothing but Plextor burners so that maybe the reason we have not had any problems with the CDRs. We use to use different media and we were cutting coasters every so often so we switched and have been very happy with the results.

I had one bad experience with taiyo's and have never retried them again. I should pick up a box and give them another try.

Henrik,
I don't know if your burner is actually testing the data or the disk. As far a i know, only the plextor premium can do error checks of the disk. That and stand alone testers. what it's probably doing is comparing the data on the cd to the image? This is good for catching an unrecoverable error but doesn't check for near failure or lower quality burns. I believe it has to be a drive implimentation. maybe it can recognize if the drive is capable of doing these tests? I don't know.

I have been using TDK blanks for some time with no problems.

Taiyo's here, burning to a PlexPremium USB - normally at 4x. Samplitude also does a "check after burn" and it comes up with no errors. I also run the C1 C2 test on the disc with PlexTools and the C1 avg/sec comes back at about 1.0 .....

After seeing all those happy Plextor posts, I went ahead and bought one.
52-32-52 Premium. And moments after I did, I want that new PX712A DVD burner Confused

Hi Michael,

What do you use to ERROR test CDR's?
Do you send DDP on CDR or audio CDR to the plant?

Henrik,
I have a Clover QA-101 analyzer. it's a stand alone checker that does 1X and 2X speeds. It checks everything including jitter if hooked up to a scope. Hooked up to a printer, it prints out the error rates and location of any unrecoverable errors. it also tells you the peak and average errors of both the 1 stage and 2nd stage error correction. What's nice is I can also use it to load in audio in that it has an AES output and will printout any errors that it encounters as i'm loading in. I believe they go for around $5000 now so they are pricey. Stagetech also makes one that i've used and it's very good as well. If you have a PC, you can get a plextor premium drive and download their software that will do some error checking. If you are sending something to the plant, they usually run it through the eclipse analyzer and if you ask them, they can send you a printout of the results, but that's after the fact and won't help trying to determine how good your CD is before you send it out. I send mine out as CD-R and not DDP image. I have an exabyte drive but no software that i like to work with that will write a DDP tape. I haven't tried sending any DDP images on CDR because some manufactures get confused when they get this and have screwed up.

Ups!!, that what I'm planning to use.
Why do they screw up? What's there to screw up? Sad

They didn't convert the image. they pressed 1000 discs of a DDP image. If your sending it, make sure they know what to do with it and that it's clearly labeled on the disc. Otherwise it should be fine if you get the feeling that they know what they're doing.
