High Quality Burner + DVD change robot



In our software company we are developing a large scale system with quite a large database. The size of the data for single copy of the application is about 30 gigabytes so currently we use 4 double layer DVDs for a single copy of our application.

The problem is that we have many complaints about the DVDs that can not be read. We investigated that the problem lays in double layer DVDs because some dvd readers have problemes reading DL DVDs.

Therefore we are looking for a burner that will guarantee maxium quailty when burning double layers.

Another thing is that we are burning on the distant computer (we are connecting to this one through VNC) so there is always a problem with changing DVDs…

… so we would like some kind of robot which will automatically switch the DVDs for us.

Could you suggest the best double layer burner with a robot for switching dvd? The price is not an issue. We just want to ensure our customers that we made all we could to provide the best quality of the DVDs.


One question:
Did you ever think about using single-layer media?
It’s much easier to get high-quality stuff with much higher quality/compatibility and the media can be burned at higher speed too.


We used to deliver the app on single layer… but since our database is growing quite quickly soon we would need to use even 10 single layers, which is not realy comfortable… Another reason for this is that we have two files which exceed the size of single layer and we would like to avoid splitting files.

We would prefer have good DL burner and a robot which will handle the changing the DVDs. Could you recommend something?


@ walkeros,

The below comments doesn’t specifically answer your original posting question but does provide information to ensure your “Application” recorded DVDs are the best quality that you are distributing to your customers.

Verbatim DL MKM001/MKM003 Mitsubishi Kagaku Media Made In Singapore is considered the best DL Media available. ALL other DL Media is considered suspect and should be avoided. Book Type BitSetting DL Media to DVD-ROM during recording enhances and improves PlayBack Viewing compatibility.

As a quality assurance measure to ensure that the “Application” recorded DVDs that you are distributing to your customers doesn’t contain any errors that would prevent the “Application” recorded DVDs for performing correctly suggest using a diagnostic software utility program similar to Nero CD-DVD Speed (http://www.cdspeed2000.com/files/NeroCDSpeed_47715.zip) or DVDInfo (http://www.dvdinfopro.com) and perform a ScanDisc surface scan and/or Disc Quality Scan on your recorded “Application” DVDs. Performing random quality assurance checks on your “Application” recorded DVDs will ensure the quality of your “Application” recorded DVDs that you are distributing to your customers. If you are unaware of how to perform a ScanDisc surface scan and Disc Quality Scans suggest reviewing the Nero CD-DVD Speed User Guide and note the ScanDisc and Disc Quality topics ->


Suggest looking into DVD Duplicators ->



Addressing your comment concerning “Robot” probably means that you would need an Automated DVD Duplicator ->






I didn’t consider the quality of the distributed media. Indeed this is very good point to change the vendor of the disks. I will suggest using “Verbatim DL MKM001/MKM003 Mitsubishi Kagaku Media” disks as a distrubution media. Thanks a lot for this point bjkg!

In fact we used the Nero CD-DVD Speed to test the quality of the disks. And there were “funny” results. You see some of the burners are “disabled” for some tests (for example the Dell TSSCorp family) and even unlocking the burners via “registry hack” causes the tests to fail in the middle… (BTW: I wonder why Nero has disabled so many vendors of the burners for the tests)… anyway… we had different results of the tests made on one dvd reader… and different on the other. On some readers there were manny “yellow” PI errors and on the others the same disk looked OK…

another thing is that we didn’t realy understood what was these errors saying… so Thanks for the provided link which explains the test process!

And the last thing are these Automated DVD Duplicators… Yes!.. these are the “robots” we are looking for:)

We have now the disks… and we can choose the suitable “robot”… now we are looking for best burner:)


The “Best” DVD Burner is very subjective opinion.

I would suggest reviewing the below Web Link ->




@ walkeros,

Concerning Disc Quality Scanning. In many circles the BenQ DW-1640 and Plextor PX-760A are considered the best available Disc Quality Scanning Drives.

Unfortunately the BenQ DW-1640 and Plextor PX-760A are discontinued and no longer in production BUT these used Drives ARE available through E Bay auctions. Although used a BenQ DW-1640 and Plextor PX-760A Drive will still produce reliable ScanDisc surface scans and Disc Quality Scans results.

Lite-On DVD Burners are also good Disc Quality Scanning Drives. Suggest visiting the CD Freaks Lite-On DVD Burner Forum (http://club.cdfreaks.com/f44/) and inquiring there as to which Lite-On Drive the informed knowledge Members recommend for Disk Quality Scanning.

If you are serious about ensuring that your “Application” recorded DVDs are the best quality that you are distributing to your customers suggest obtaining a BenQ DW-1640, Plextor PX-760A, and a “Recommended” Lite-On Burner and installing these Drives in a dedicated “Disk Quality Scanning” computer with all the recommended Disk Quality Scanning software programs. With these 3 “Scanners” and the correct proper “Disk Quality Scanning” software you can compare the Scanning results between the 3 Drives and determine if the “Application” recorded DVDs you are producing are if fact quality error free Burns. Performing random “Quality Control” ScanDisc surface scans and Disc Quality Scans on your “Application” recorded DVDs will ensure that you are producing a quality product.



[QUOTE=walkeros;1997756](BTW: I wonder why Nero has disabled so many vendors of the burners for the tests)[/QUOTE]Erik Deppe,developer for Nero CD-DVD Speed is told what drive mfgrs say ya or na for testing. So it is not Nero but the drive mfgrs.

What brand/model drives do you have now? Do they have the newest firmware?

And yes the media is very important and the place they are made. Only use Verbatim +R DL MIS = Made In Singapore.


I had a look on BenQ DW-1640, Plextor PX-760A and the drives really looks good. The Plextor’s PoweRec technology looks interesting at list on advert… I’s a pity their production was discontinued. I will suggest obtaining one of these drives if possible or look for successors of them. I will also post to the Lite-On forum as you said.

I will note that it would be good to do the quality tests on the three drives and compare them. I guess some drives can behave better with certain type and size of written data then others so it’s good to test using “production data” on each and compare the results.

Thanks for your invaluable help bjkg!

Lately we had HP drive (I don’t remember the exact version of firmware) pluggable via usb (Hm… could usb connection affect the disk quality??)… but we replaced it as the system stopped detecting it. We bought TSSTcorp SE-204N in hurry, but we would like to buy another one which has firmware aware of quality.

After buying it the firmware was updated. Here is a dump from Nero info tool.

Drive Information
Drive                      : TSSTcorp CDDVDW SE-S204N 
Type                       : DVD-RAM Recorder
Firmware Version           : TS00
Buffer Size                : 2 MB
Date                       : ?
Serial Number              : SE-S204NFirmware
Vendor Specific            :    1001       
Drive Letter               : F:\
Location                   : 2:0
Mechanism                  : Tray
Read Speed                 : 16 , 8  X
Write Speed                : 48 , 40 , 32 , 24 , 16 , 8 , 4  X

Thanks for the explanation why some tests are locked by Nero for certain vendors. We will have a new test relese of application in two weaks so I will unlock the tests and try to use the TSSTcorp drive we currently have. I will do the same after we bought new burner.

Thanks Bob!


@ walkeros,

Do not waist ANY time “look for successors of them” (BenQ DW-1640 or Plextor PX-760A) because the quality of these “successors” Drives are not the same.

Although the name “BenQ” and “Plextor” is in existence the Drives that carry the “BenQ” and “Plextor” name brand are not actually manufactured by “BenQ” and “Plextor” anymore and the quality of the newer “BenQ” and “Plextor” Drives is NOT the same as the highly desirable BenQ DW-1640 or Plextor PX-760A. Newer is NOT always better. As an example the current replacement for the Plextor PX-760A is the PX-800A and is not manufactured by Plextor but is actually a Re-Badge NEC/Optiarc (AD-7173) and there is a world of difference between the quality of the old highly desirable Plextor PX-760A and current PX-800A.

As previously stated the BenQ DW-1640 and Plextor PX-760A are considered the best availed Drives for performing Disc Quality Scanning. Unfortunately the newer “successors” of these Drives are not desirable and although carry the “BenQ” and “Plextor” name brand the quality of these “successors” has drastically gone downhill and the Disc Quality Scanning properties of these “successors” drives is highly suspect and unreliable.

As previously mentioned e bay auctions is a viable source in obtaining the highly desirable BenQ DW-1640 or Plextor PX-760A Drives. It might take a little time and effort in obtaining the highly desirable BenQ DW-1640 or Plextor PX-760A Drive from E Bay but concerning reliable ScanDisc surface scans and Disc Quality Scans results the time and effort is worthwhile.


PS - For calcification BenQ DW-1640/DW-1650/1655 Drives are of the same Series and all produce reliable ScanDisc surface scans and Disc Quality Scans results. The BenQ DW-1640 Firmware was more mature and as such was considered the more desirable “Scanner”.


On the other subject (robots/automation), some things to keep in mind:

  1. What OS are you burning from? All robots come with windows software, some come with Mac software and almost none of them come with Linux software.

  2. Are you planning to use a stand-alone duplicator? If not, what level of software integration are you expecting? If you’ll simply be creating five to ten DVD+R masters by hand and then manually loading the machines with 100s of blanks, they can all do that, pretty much. If instead, you want your application to integrate with the hardware or with the SDK for the hardware, then you’ll need to talk to the makers about integration and SDKs.

  3. Most of the 50-disc and up robots are controlled via a serial port, so if there is no SDK or the SDK does not provide the flexibility you need, you can always talk directly to the loader itself.

  4. Will inkjet/thermal printing be part of the workflow? If so, make sure the loader you choose works with the printing type or printer you want it to. Usually they are sold as a package with the duplicator.
