Optical Quantum Blue CD-R Overview

Optical Quantum Blue CD-R Overview

Hi everyone,

Yesterday, I received a spindle of “Blue CD-R” from Optical Quantum. This brand is a subsidiary of Vinpower Digital and the discs are manufactured by Optodisc Taiwan:

Optical Quantum Printable Blue CD-R 1

I brought this spindle because the “Blue CD-R” caught my attention. Usually, CD-Rs are produced in a very light green color, but these discs should be different. These discs are marketed as having a “Blue AZO Burning Die”, which should be superior than standard CD-Rs.

The discs are rated at 52x and can hold up to 700MB of data or 80 minutes of audio, which is standard of CD-R discs. This batch also appears to look like a dark green color, but not too much blue. The discs are printable too.

Checking these discs in Nero DiscSpeed gives us a Media ID Code (MID) of 97m24s01f, and is identified as “Taiyo Yuden”. I’m not sure if this is legit, as it is my understanding that CMC Magnetics has the rights to use Taiyo Yuden codes, but since these are manufactured by Optodisc, I have my doubts.

It has to be noted that these brands tend to source their discs from different suppliers, usually from Ritek, which does use Ritek codes in their discs. Some other brands source their discs from CMC Magnetics, again, using CMC-MAG-xxx codes. In this case, I wonder if Optodisc is legitimately making “Taiyo Yuden-quality” discs. There are some articles that seem to refer to Optodisc making Taiyo Yuden-quality discs, so that may be the reason they are using their media code.

I checked these discs on 4 slim drives that I at the moment. Since I’m on vacation, I don’t have my usual Lite-On drive to check these, but this will give you an idea of what to expect when using them on Slim drives. I also haven’t burned them, so this will just be purely disc information below:

So far, the most reliable slim drive I have at the moment is this one, which reports burning these discs at 10x, 16x, 20x, and 24.

Panasonic UJ260

Optical Quantum Printable CD-R - Panasonic UJ260

This is a Blu-Ray drive which has been my best Blu-Ray burner in years. This drive also supports CDs and DVDs, but usually burns at low speeds. This is why Nero DiscSpeed is reporting just 2 speeds: 8x and 24x.

LG BP60NB10

Optical Quantum Printable CD-R - LG BP60NB10

This is an LG “4K UHD official” drive. This one gives me headaches sometimes since it seems to lose focus while reading some times, a behavior I don’t see on any other drive. Maybe it’s faulty, but I also found that this drive depends heavily on the quality of the USB port and cable since it’s USB-Powered. This drive supports burning these discs at 10x, 16x and 24x.

LG GT80N

Optical Quantum Printable CD-R - LG (HP-branded) GT80N

This drive is part of an HP laptop, which is why it is branded as HP rather than LG, but it is actually made by LG. On this drive, the disc is supported at a speed of 10x, 16x, and 24x.

Final Thoughts

These discs are marketed as Blue, but they seem to look dark green. This is still different from the majority of discs that look very light green. It seems to burn at a maximum speed of 24x on all of these slim drives, probably because of the use of the Taiyo Yuden media code, although nowadays, most media and drives burn most discs at 24x for Slim drives and 48x for desktop drives.

I haven’t burned these discs yet. That will come when I have access to my Lite-On drive featuring LabelTag, as I also want to see how a label would look on these discs too. I expect these to burn flawlessly at 48x in that particular drive which I have trusted since 2010.

You can get these discs on Amazon below:

Verbatim 4x BDXL 100GB Blank Media

Verbatim 4x BDXL 100GB Blank Media

Hi everyone,

Yesterday, I received my very first BDXL media. These are way more expensive than BD-R and about twice the cost of BD-R DL media.

For my first BDXL recordable media, I decided to get the Verbatim 10-pack spindle. These seem to be one of the lowest-priced media when compared to 3-packs or 5-packs variants of other manufacturers.

These BDXL discs are rated at 4x, but my LG WH14NS40 crossflashed to the WH16NS60 firmware detects them as having a write speed of up to 8x.

The Media ID is VERBAT-IMk-000.

On my Panasonic UJ260, these have a maximum write speed of just 2x.

I added files to burn using ImgBurn, and made sure to use the most space possible. I then started the burning process on my WH14NS14 at the maximum supported speed of 8x.

Añadí archivos a ImgBurn y me aseguré de llenar el disco lo más posible. Luego, comencé a quemarlos con mi LG WH14NS14 a la velocidad máxima de 8x.

It seems the drive use a Z-CLV (Zoned Constant Linear Velocity) strategy to burn these discs. The write pattern was as follows:

  • Layer 0: 4x -> 6x -> 8x
  • Layer 1: 8x -> 6x -> 4x
  • Layer 2: 4x -> 6x -> 8x

We can see the pattern below:

Some times, when the writing was at 4x, the drive would go down to 3.3x for about 1 second or 2:

The same happened when the drive was recording at 6x, going down to 5x for a second or 2:

The drive successfully burned this media, having an average speed of 5.7x:

Burning VERBAT-IMk-000 Average speed 5.7

Verification was slower than the writing itself, as it limited the read speed to 6x:

The verification was successful and no errors were reported:

The average read speed was 4.3x, slower than the 5.7x average when writing to it. It also seems that while ImgBurn set a read speed of up to 6x, the drive went all the way to 9x, according to the Maximum Verify Rate.

Here, we can see the written disc with its Z-CLV zones:

Conclusion

These discs seem to be compatible with the LG WH14NS40 Blu-Ray writer. They also burn at a faster 8x speed which is more than its rated speed of 4x. The drive was able to successfully burn them and read them. These discs, while expensive, allow us to write up to 100GB (about 93GB of actual storage) on a single medium. It would have taken us 4 25GB BD-R or 2 50GB BD-R DL media to write an equivalent amount of data.

Unfortunately, I don’t have any BDXL scanner I can use to test the quality, but the media can be read back on the LG drive as well as on my Panasonic UJ260. The latter seems to read the disc in Z-CLV too, but it was able to read the data back successfully too. It is just slower than the LG drive.

If we compare the price of having 10x 100GB Blu-Ray discs to owning a 1TB Hard Disk Drive, we can see that the BDXL media is a couple dollars more:

The BDXL media on eBay (It was at $53.15 at the time of puchase):

On Amazon. They seem to have lowered the price to $49.99 at the time I took this screenshot:

Ultimately, it all would depend on your needs. Personally, I like to write data that will not be used frequently on optical media, while having frequently-changing data on the discs. I’ve also had a bad experience of having Hard Drives fail, and while I’ve had optical media fail too (Some bad Blu-Ray batches that deteriorated in a couple of years), the data loss is not as much as losing a whole hard drive. Remember to back-up your data!

Ritek Mini CD-R: Part 2

Ritek Mini CD-R: Part 2

Hi everyone,

Today, I burned a few more Ritek Mini CD-R media, where I found out they have a surface issue:

Ritek CD surface issue 2

I didn’t realized this, but it seems to be a plant manufacture problem. I opened another of the 100-pack I have and it have the same problem.

The problem is that the data was burning fine, with no errors on my Lite-On iHAS524, but it failed to verify on some parts of the disk, as it was approaching the end. I was burning them at 24x, the maximum speed it supports on the writer.

I decided to use the Optiarc AD-7561A drive I have to see if it would burn fine with it, since slim drives usually burns at a lower speed.

M Way External DVD Drive - Colorful Flame Pattern - Teardown - 10
Optiarc AD-7561A

When the CD is inserted in this drive, it is detected as a 10x media:

I burned the CD with this drive, where it was able to both burn and verify successfully. It also seems that the drive burned surface is a bit darker than with the LiteOn drive, so maybe that makes it handle the bad surface better.

Quality tests

I burned 2 CD’s with the Lite-On drive where both burned successfully but didn’t read fine. One was able to read completely, but lowering the read speed at the bad section. The other one failed with unrecoverable errors.

Let’s see their quality tests with the LiteOn drive first, followed with the Optiarc drive:

CD #1 – LiteOn

This is the CD that was able to read completely but lowers the speed. When playing it back, it pauses while reading the wrong area. It can be ripped, but will struggle in the bad area. The ripped file appears to be fine, but EAC reports timing problems. Listening to the track didn’t revealed any issues.

You can see the excesive amounts of C1 and C2 errors.

CD #2 – Optiarc

Here is another burn of the same data, burned with the Optiarc drive and tested on the LiteOn drive. You can see that it only reports a maximum of 10 C1 errors and no C2 errors. The quality score is 99%. Same media, but burned on a different drive, at 10x speed.

CD #3 – LiteOn

This CD failed to test properly. Once again, you can see the excessive amounts of C1 and C2 errors. The positions of the C1 and C2 errors seem to match the ones of the previous LiteOn burn.

CD #4 – Optiarc

Here is another burn of the same data of the previous burn. You can see this time it was successful, with only a maximum of 8 C1 errors and a total of 19. Again, the quality score is 99%, which is the same as the other Optiarc-burned media.

Conclusion

As seen from the above tests, it seems the Optiarc AD-7561A drive can successfully burn these discs if we intend to use all of its capacity. Maybe it is because of the slower burning speed, or because the optical laser can burn them better than the one on the LiteOn drive.

The LiteOn drive can only burn these CDs at 16x and 24x, while the Optiarc can only burn them at 10x. I’ll test burning a disc at 16x at a later time and see if it works. If not, I’ll continue using the Optiarc drive, which has proven to burn them correctly and without any issues.

Ritek Mini CD-R Photos and Quality Tests

Ritek Mini CD-R Photos and Quality Tests

Hi everyone,

Yesterday, I received some Pocket/Mini CD-R I purchased on eBay, which were being sold for cheap due to them not being branded or not having their specs listed.

The seller was selling 3 packs of 100 unbranded silver surface Mini CD-R, and since the price was lower compared to other branded media, I decided to buy all 3.

Ritek Pocket CD-R 210MB media - 1

The discs were wrapped with no spindle.

Ritek Pocket CD-R 210MB media - 2

The discs have a silver surface:

Ritek Pocket CD-R 210MB media - 3

Here we can see a single CD-R:

They have the usual light green color on the data side.

The disc loaded fine on my LiteOn iHAS524 drive. I launched ImgBurn which says that the discs are made by Ritek. Their media ID is 97m15s17f:

Pocket CD 97m15s17f Ritek Media 1

They also have a capacity of 210MB or 24 minutes and a maximum write speed of 24x.

Pocket CD 97m15s17f Ritek Media 2

This is the first Mini CD I use with this LiteOn drive, which has the unique LabelTag feature to add labels to the data side. The software detected the disc and a label can be created:

Pocket CD 97m15s17f Ritek Media 3

I burned some of these CD-R with Nero Express, which allows the creation of the label on the same run. I also burned them at its maximum speed of 24x without any failure.

Quality tests

I ran a Disc Quality test using Nero DiscSpeed. Below you can see the results of those tests. I limited the test to the first session of it, as the second one is the label produced with the above software and contains unreadable data. This makes the test fail. By limiting it to the first session, we can get the actual data track quality.

Disc 1

The first test gave us a maximum of 14 C1 errors with a total of 58. The average was 0.11. There were no C2 errors reported. The Quality Score was 98%.

Disc 2

This test was perfect! No C1 or C2 errors were reported, making the Quality Score be 100%.

Disc 3

This disc had a maximum of 9 for the C1 Errors with a total of 13. The average was 0.07. No C2 errors were reported. The Quality Score was 99%.

Disc 4

This final disc I burned had a maximum of 13 C1 errors with a total of 27. No C2 errors were reported. The Quality Score was 98%.

Final Thoughts

These blank CD-R media seems to be good to write small amounts of data. This could be an MP3 album, some photos, or software you’d like to archive. The burns seem to be of good quality and the 24x burning speed is adequate. This sure was a great find on eBay!
