The best disc I've ever burned

Postby dolphinius_rex on Sat Aug 26, 2006 1:58 am

This is a disc I burned for my longevity study.... it amazed me so much I had to post the scans:

Nice work dude and I feel this indeed contributes significantly to the longevity study....

However, you above all others should know the concept of parity and jitter are largely meaningless in terms of "best" burns. It's not a resultant that can be used to ultimately determine overall quality of media, nor the disc.

Parity and jitter and pretty graphs are all well and good - but the more serious metrics we should look to (which our AudioDev homies are) are things like media geometry and reflective index measurement.

I'll never go as far to say a disc is the "best" I've seen, based upon the measurements you have used, alone.

All the same - nice work bastid. ;)

Well, with my limited equipment I have on hand, and based on the results returned, I would say it's the best I've burned. Now whether or not it will hold up better then other discs is another thing completely!

And of course, this disc will be shipped off for CATS testing next week :wink:

"Best" is indeed difficult to justify- even without going to properties independent of the drive doing the reading (like zebraxor mentioned).

That's an amazingly low PIE level on both drives, but these can vary with drive temperature etc. The PIF count is nothing spectacular though, and I consider this to be more important.

I'm very curious as to what CATS measurements you're getting (just PI/PIF or other data) and am looking forward to more results!

Hrm.... Going from past experience, I should get the following:

Min/Max/Avg/Lower/Upper for:
RN
SVY
PIE
POF
PIF
PI Sum 8
I3/I14
I14/I14H
ASYM
R14H
TPP
FE
Radial1
Radial2
Beta
I14H LV
I14H RV
I14H DV
TCS
DPD Amp
DPD Asym
RRO
DC Jitter
DC Neg Jitter
DC Pos Jitter
Bottom Jitter

Physical Characteristics, tested for layer 0 (not dual layer)
LLO
ODIA
IDIA
ODDA
IDDA
STA

So it'll be a little more in depth then your standard PIE/PIF/POF/Jitter/Beta testing I think :wink: But unfortunately I won't know just what will be included in the testing until I receive the results. But I *HAVE* received all of the above in previous tests! :D

Hmm...so the '111 is able to do something good!

I've been less than impressed with mine so far...
BenQ 1655, BenQ 1620, LG 4167, Plex PX-716SA, Samsung SH-S162L, SH-S182M, Pioneer 111D, Lite-On SHM-165H6S and 1.9TB of HDDs to feed 'em and an X2/4800 to crunch for 'em.

...can't complain with mine. It took Pioneer to give me three different revisions of the hardware to get a decent one however.

Actually in general I think the DVR-111D is an excellent drive. It burns media quickly, and the quality is pretty good in most cases, and sometimes quite excellent. I'd rate it as my second favourite drive, right below the BenQ DW1640.

Well, so far, my 1655 beats it with every type of disc I've tried...if BenQ's really canning their opticals, I need to jump on another 165x ASAP...

It does seem to do very well with Verbatium 16x DVD+R's, though.

And, given what my 1655, 1620, and 4167 can do...it's hard to be impressed with anything.

You should try any DL media in your 111. Mine burns stuff like the Ritek that even my pickiest player can play. None of my BenQ's can even touch rhat stuff, although my 1640 improved quite a bit it seems with the latest R firmware.

You know I have to ask about whether that MXLRG03 disc has the short or long hub serial numbering scheme... :lol:

If you look in my longevity study thread you'll see ALL my serials listed :wink:

But since you ask, it's short type.
