burn speed
tower
I've purchased 100 of these:
TAIYO YUDEN WHITE PRINTABLE CD-R 52X M7008101162802 100
0.3500
80 MIN 100SBZM
and I'd like to get a consensus idea of what would be the best burn
speed for playability and reliability. I've seen where too fast is not
good but I've also seen where too slow is also not good.
Thanks,

Depends on your drive. You need to measure error rates at different
speeds and find out.

My Plex seems to be best a 8x.
An older Phillips drive I have works best at 4x or 8x.

The determining factor is usually the playback device, not the burning
device.

Well, it's both. The quality of the eye pattern coming off the head of
the player has to do both with the consistency and contrast of the image
on the disc and with the quality of the player optics.
Better players also have better error concealment, so you can get away
with more errors on the disc in the first place.
The way I look at it, your goal in life is to get as close as possible to
zero playback errors.

As you pointed out to me previously depending on your drive and the
associated software you use to measure errors, you may not be seeing
all your errors. Most of us do not have any equipment that gives
definitely accurate information. I do have a drive that gives me some
useful error information and a jitter figure as well.
I tried some special Mitisui mastering CDR's which are supposed to
work best between 1 - 12 X. I burned them at various speeds and found
I actually got the lowest jitter at 16X. Go figure.
For the 48X TY's I find no errors and low jitter at 24X & 32X. at
48X I see an occasional error when burning an audio discs but not when
burning a data disc. I usually burn them at 24X.
I also have a batch of 52X TY's but I haven't tried them yet.

Jitter ? That's more the writer, not the media. Look for C1, C2 and CU
error rates.

With MY burner I get the least jitter burning at 16X; no detectable
C1, C2 or CU errors at 16X or 8X or 24X.

No C1 errors ?!!!! That would be a first for any CD anywhere. How are you
testing ?
On a factory-pressed disc you could expect at least 20 C1 errors per second,
and no C2s if in pristine condition..

The OP question is how does someone (presumably without fancy test
equipment) tell which speed his CD burner gets maximum quality on TY
52X disc. Since it is very doubtful the ability to read C1 errors is
assumed do you have any practical suggestions?

Get a Plextor Premium and use the included PlexTools Pro software to test
the CDs from whichever burner/s, also replicated ones.

So that's your advice to the OP?
Plextors can accurately detect C1 errors? IF so what do you get on an
average burn?

Scott said "the drive", not "the drive model". It is about the actual
drive and the actual batch of disks. Plextools can come in real
convenient, you do however need a premium plextor to get the really
usable version.

You also need to understand `best'. Best = lowest error rate next week
is very different to Best = highest chance of being able to get all the
data back in 100 years. These are very different, and drive you media
choise.
For the first, TY seems to be well regarded. For the second, MAM Gold
Archive, nothing else unless NBS has updated the tests and shown
another is better.

My Advice is buy or borrow a Plextor Premium, and test each media at each
speed recorded on each drive that he uses.
But also advice not to sweat it too much, unles an obvious problem shows up.
Yes, the Plex Premium does - google it. I get anything from 10 to 30 C1
per second on SKC media (when just written). Just did some commercial
replicated CDs that both had around 40 per second on average.

8-16X burns work well with Taiyo Yuden CDRs and marginal players can
play them.

Yeah. Assuming it is not possible to get a Plextor Premium, just
burning at speed somewhere in the middle of the CD drives range is
probably safe.

I guess I'm going to have to buy a Plextor next time.

As I said earlier, I cannot read C1 errors with any accuracy, but I do
get C2 errors reliable enough I can clearly tell a good burn from a
fair one from a bad one. Also the jitter spec is useful. Based on
that info from the Nero CDSpeed tool, I am confident it is fine to
burn 48X TY's at 24X on my Samsung with consistent good quality.
Mileage will vary with other burners, but I suspect 16X or 24X is
optimal for most burners. I have seen the jitter increase when I burn
too slow, so I do not recommend 8X 4X 1X for my Samsung anyway.
