General discussion about recordable CD, DVD and BD media and write quality testing.

<edit>This post also does not correctly answer your question and also contains a link to some material that is interesting in its own right. For the actual answer to your question, please skip forward one more post to here. </edit>

Here we go, this is the other link I was looking for:

http://club.cdfreaks.com/showthread.php ... post420106

Before you question why Media Sciences and Clover (the original source of BoSkin's information - see the second link at the bottom of his post) seem to be in disagreement, note that the letter grades Clover details are their own interpretations. They claim that their definitions "reflect generally accepted practice in the industry", but also admit that their "criteria are somewhat arbitrary".

I believe the "+" and "-" indicate the writing strategy (long or short) but will have to get back to you on that.

I believe I confused media grade and media type. Read through this thread as well, taking particular note of spath's comments:

http://club.cdfreaks.com/showthread.php ... adid=49703

If I read this correctly, the A,B,C/+,- designations define disc characteristics that help the drive select its writing strategy. They would thus have nothing to do with the letter quality grades from Media Science and Clover that I originally posted.

See also this article on OPC where it discusses three different write strategies with either low or high beta:

http://www.mscience.com/faq64.html

I will leave the original posts (with notes indicating that I believe them to be in error) for the sake of completeness and because they have some interest in their own right.

The quality of a disc is determined after it is manufactured. Discs must have data (CDDA or CD-ROM) content for a quality test based on error rates. Disc quality is the interaction of the recorded disc with the playback mechanism(s) under varying speeds and conditions.

The codes described above would have to be OPC codes, as the quality of a disc is not predetermined (put on a stamper) before it is made.

Inertia: Some CD testing units are capable of testing a CD-R without any data recorded on it. These are usually tests that have to do with shape, the pre-made grooves and reflectivity. All these things are important for a CD-Rs quality! :D

but yes, you don't "stamp" the quality rating on the CD-R during production...though I'm sure several manufacturers (*cough*princo*cough*) would love it if they could!

Thank you for the information. That was very informative- esp. the Media Sciences site has a wealth of information in the FAQ. :D

I think I may be using the term ATIP in a somewhat casual or nonstandard manner- it may come from using this forum as a main source of information. :wink: I guess what I referred to as ATIP is the manufacturers code which is derived from the lead-in time (complement to 99m59s75f). What I requested in S16, then, is lead-in and lead-out time. I will have to do some more reading as to what else is available in the ATIP. :o spath mentioned a maximum recording speed (possibly obsolete for practical use) and here we have OPC strategies.

MediumRare:

Do you really want to replace "ATIP" in S16 by "ATIP Lead-in and Lead-out"?

I was thinking about "ATIP Lead-in". SmartBurn's "ATIP Lead-in" seems to correspond to CD Speed's "Code"; otherwise, both display Manufacturer, Disc Type, Material/Recording Layer, and Nominal Capacity, so it's reasonable to ask for similar information from KProbe.

Perhaps KProbe should also display Recording Speed, or SMART-BURN Speed Limit if this feature is implemented.

Neither SmartBurn nor CD Speed display "ATIP Lead-out". Thus I'm wondering whether it is really needed.

Copy/paste from smartburn:

This Disc is designed for CD-RW/COMBO Drive Only.
Disc Type, Material = HSCD-RW, Phase Change
ATIP Lead-in = 97m 10s 00f
Norminal Capacity = 702.83MB (79m 59s 74f)
Disc Manufacturer maybe = TDK,RiTEK,COMPUSA
SMART-BURN Speed Limit = 12X

The red text is the ATIP Lead-Out of the disc. Smart burn most deffinatly DOES list it :wink:

actually, so does CD Speed, under "capacity:"

and I also belive K-Probe should include the Lead-out on the display :D

I'm not sure anymore- :roll: yesterday I would have said Yes, but in preparing the previous post, I saw that I was using the CD-Identifier nomenclature. I guess we should leave it at that. It doesn't really matter what we call them- ATIP or Lead-In or Manufacturer's code on the one hand or Lead-Out or Nominal capacity on the other. I think the information should be there though.

Medium Rare: I checked out all you media info, and I agree with your manufacturer findings 100%

I cross referenced the ATIPs on instantinfo.de as well as my own personal archives.

I also agree that the terminoligy is not important, as long as both codes are available, preferably not in HEX though :P

MediumRare, dolphinius_rex and rdgrimes:

Sorry for the confusion about "ATIP Lead-out" vs "Nominal Capacity", but let's try to clarify this detail, as well as some more important aspects.

For dolphinius_rex's example of SmartBurn's "Norminal Capacity = 702.83MB (79m 59s 74f)", if the ATIP start of lead out 79:59.74 specified the nominal capacity directly, apparently we would have 719,998 KiB = 703.12 MiB of mode 1 user data (where Ki = 1024, Mi = 1024 Ki). However, if we subtracted 2s first, 79:57.74 would yield 719,698 KiB = 702.83 MiB, i.e., SmartBurn's value. On the other hand, if we subtracted 2.5s, 79:57.37 would yield 719,624 KiB = 702.76 MiB, a too small value. Note that 702.83 MB is also reported by CDR Media Code Identifier and CDR Atip Reader, whereas CD Speed reports 703 MB; see the examples in

http://www.cdbest.net/2003/ReadNews.asp?NewsID=1384

Thus apparently all these programs subtract 2 seconds from the ATIP start of lead out for calculating the nominal capacity.

I agree that the terminology is not important, and that is better to have more information. There is no limit if such information is output to the summary file, as suggested in S15. However, in connection with S16, it might be wise to select a subset of the ATIP info, since the saved graphic files already have headers with 9 lines.

The Read TOC/PMA/ATIP command (data format 0100b) description in the NCITS MMC-2 document calls these numbers "ATIP Start Time of Lead-in" and "ATIP Last Possible Start Time of Lead-out".

In response to KCK's suggestion to limit the amount of ATIP information displayed in the graphics files, I think that these two parameters would be the logical choice to include.

There are a few other parameters that could be included, but they don't seem to be of much value. The most interesting would be "Lowest Usable CLV Recording Speed" and "Highest Usable CLV Recording Speed", if they contained useful information. Unfortunately these seem to be remnants of an earlier time (valid range = 2x, 4x, 6x and 8x) that never caught on. I've not seen any actual data in these fields for any of the CD-R's I've looked at. I guess that's not too surprising, since all the CD-R's I've looked at can be written at much higher speeds than 8x.

By the way, I'm sure you guys know this, but for those who haven't looked, KProbe reports the ATIP information for blank discs (along with a lot of other interesting information for both blank and recorded discs) on the "Disc Info." tab.

Thanks for the tip!

I got it and the new strategy seems to have done the trick. :D
All the discrepancies I mentioned seem to have been resolved. The new version 1.1.10 now shows the following manufacturers for these cases:
Code: Select all
Ricoh 24x and HR-120 24x

Disc Type = CDR (C-)             
old   Manufacturer = Ritek Co.
new   Manufacturer = Ricoh Company Limited

Code: Select all
Tevion Silver Blue (1)

Disc Type = CDR
old   Manufacturer = Xcitek
new   Manufacturer = AMS Technology Inc.

Code: Select all
TDK Metallic 48x

Disc Type = CDR (B-)
old   Manufacturer = Ritek Co.
new   Manufacturer = TDK Corporation

Code: Select all
Tevion Silver Blue (2)

Disc Type = CDR (B+)             
old   Manufacturer = Ricoh Company Limited
new   Manufacturer = Digital Storage Technology Co., Ltd.

Code: Select all
Unknown

Disc Type = CDR
old   Manufacturer = Ritek Co.
new   Manufacturer = Ricoh Company Limited

Code: Select all
Ricoh 1-4x

Disc Type = NORMAL CD-RW
old   Manufacturer = Ricoh Company Limited
new   Manufacturer = Digital Storage Technology Co., Ltd.

The manufacturers now agree with CD Doctor- even the Ricoh rewritable. See http://www.cdrlabs.com/phpBB/viewtopic.php?p=50068#50068 and following for a discussion on this one, though.

A quick check of some "exotic" disks with no discrepancies didn't show any changes.

Thank you Karr!!!

1.MInfo is a tool like Smartburn.exe , and one day it will replace
smartburn.
2.If you have any idea about this tool , welcome to reply to me !!
Thanks a lot.

Thanks Karr! Another nice set of improvements. I haven't had a chance to check out all the new improvements, but it looks good so far.

Did you guys also download CD Media Info version 1.1? It looks like Karr's SMARTBURN.exe replacement. It is quite nice also, although I do wish the window was a little taller so I could see all the information without scrolling. The entire window can be resized (if you pick the border very carefully), but the list-box remains the same height.

<edit>Now I see that some of you have... That will teach me to eat breakfast between posts - too much can happen in 20 minutes here. :D </edit>

Hey! Give Karr a break! :x :wink: 8) :) It is common practice to use multi-digit version/build numbers. Right-click->properties->version on just about any DLL in system32 and you will see Microsoft does the same.
