Well I must say no I have never tried The Samsung 40x on my F1 yet as I mostly use Verbatim Dala Life Plus 40x with Super Azo and so far I have found them to be the most reliable CD's !!!

We cannot find such media here for testing

(in reply to john)

I have this media and will test it as soon as I get my Yamaha. It is in the mail. I only know how to test the speed. That means no error checking unless I can find out how.

The Samsung CD-R80 40x (inkjet printable) worked fine. I burned at 44x with no problems with firmware 1.0c.

(in reply to john)

Glad to here it !!!

The next two types of CDR are doing well not only at 44x (OWSC enabled) but even at 52x (Smart-Burn disabled; yet, I've not tried enabling of it):

1.Circuit City (write speed is not explicitly specified):
Manufacturer : Prodisc
Code : 97m32s19f
Disc Type : CD-R
Usage : General
Recording Layer : Dye Type 9: Short Strategy (Phthalocyanine)
Recording Speed : n/a
Capacity : 79:59.74
703 MB
Additional Capacity : n/a
Overburn Capacity : 81:36.18 (717 MB)

2. Verbatim 48x:
Manufacturer : Mitsubishi
Code : 97m34s23f
Disc Type : CD-R
Usage : General
Recording Layer : Dye Type 3: Long Strategy (Cyanine, AZO)
Recording Speed : n/a
Capacity : 79:59.73
703 MB
Additional Capacity : n/a
Overburn Capacity : 81:44.18 (718 MB).

The next one writes reliably at 44x but I've not tested yet at 52x:
1. FujiFilm (write speed is not explicitly specified):
Manufacturer : Taiyo Yuden
Code : 97m24s01f
Disc Type : CD-R
Usage : Audio
Recording Layer : Dye Type 1: Long Strategy (Cyanine, AZO)
Recording Speed : n/a
Capacity : 79:59.73
703 MB
Additional Capacity : n/a
Overburn Capacity : 82:36.00 (725 MB).

The next one is reliable at 32x (as specified) but inconsistent (it depends) at 44x:
1. SmartBuy 32x:
Manufacturer : Prodisc
Code : 97m32s19f
Disc Type : CD-R
Usage : General
Recording Layer : Dye Type 9: Short Strategy (Phthalocyanine)
Recording Speed : n/a
Capacity : 79:59.74
703 MB
Additional Capacity : n/a
Overburn Capacity : 81:36.18 (717 MB).

From CD Freaks:
Fuji (TY) with Capacity (lead-out) of 79:59:73 is typical for Fuji labeled at 24x/32x.
Fuji (TY) with Capacity (lead-out) of 79:59:72 is typical for Fuji labeled at 40x or 48x.

[:(!]I had 3 of these CDRs and have burned 1 at 44x, far not full 80 mins though. It came out Okay. It is not a surprise to me as my other 32x certified bunch of CDRs (Prodisk make) burns at 44x with fifty-fifty (32x burns reliably).

When get a chance, I'll post how the other two FujiFilm disks came out at 44x. They are eligible for DT@2 but now I have a lot of good Verbatim CDRs.

PS. At this point, I've decided to perform the check and copied on the fly (almost 75mins) MS Visual Studio 6.0, Enterprize Edition.

The reader used is Sony CRX220E1 at 52x.
The writer is Yamaha F1-ZE at 44x (OWSC disabled).
Before copying, I ran Nero CD Speed. It read at 52x perfectly well.

The copying took 3m34s.
Thereafter I put the new CDR into Sony drive as the Yamaha cannot retrieve ATIP info from a finalised CDR.

The CD Quality test did find severe issues at approximately 60 mins but thereafter it finished Okay.
Scan Disk for surface errors found 10 damaged sectors also around 60 min position:
Starting surface scan
Good: 98.81 %
Damaged: 1.19 %
Unreadable: 0.00 %
Surface scan completed

Now, I put the CDR back into the Yama.
Results of the CD Quality Check are much-much better: no problems! I already know that the F1 is a better reader than the CRX220E1. On the other hand, they read it at 44x and 52x accordingly...

Next test - Surface Scan. Yama reports no problems. Well, it cannot report on damaged sectors.

Final test - File Test by the Yamaha. For 7277 files - no problems. Average speed 12.8x.

What's the conclusion?
Seems like it is indeed possible to use these CDRs at 44x. However, I'd say, it's better to write at no more than 40x (F1 does not support this speed while the CRX220E1 does).[^][xx(]

(in reply to john)

btw, using the F1E for scanning discs is not suggested, since it doesn't support C1/C2 error reporting, use the Sony drive instead!

(in reply to john)

Also according to some information, Fuji 40X based (not Fuji 40X based at TY) seems to produce the lowest Jitter at 44X

(in reply to john)

Hi John,
I'm back after work and reran the tests on that CDR. Only the Sony drive was used.

First surprize is the reported length of data. Nero says 69:50:14 while the CD Speed - 69:49:60. As far as I can recall, at the time of recording the Nero reported some 74 mins. I can't figure out what these discrepancies mean.

[}:)]I ran Scan Disk two times with a few minutes break. Results are different! First time the CRX220E1 found 18 damaged sectors. Here is the CD Speed report:
Starting surface scan
Good: 97.85 %
Damaged: 2.15 %
Unreadable: 0.00 %
Surface scan completed

The second time it ran visibly slower and picked only 9 bad sectors:
Starting surface scan
Good: 98.93 %
Damaged: 1.07 %
Unreadable: 0.00 %
Surface scan completed

Finally, I ran the Quality test. It had two yellow surges (are these C2 errors?): at about 49 min and (much higher) 54 min positions. The average speed is 47.3x.

I cannot explain these inconsistencies. However, can repeate the statement from the preceding post: looks like it is possible to write to these FujiFilm CDRs at 44x but it's better to somewhat calm down.

It is interesting that if I tested only with the Yamaha F1 drive, all these issues would go undeleted! Thanks for the remark, John!
Now, who is gonna convict me that the Yama is unconditionally better than the Sony?!

A question for you, please. I have only one type of the FujiFilm branded CDRs: by Taiyo Yuden, right? And, based on the jwcrim's post, they are not 40x approved. But what the "Fuji 40X based" mean? Have the Fuji begun themselves making the CDR media?[?]

(in reply to john)

[:I]Previous tests convinced me that slowing down the read speed may improve the CD quality as it appears to its data requester. So, I checked that FujiFilm CDR one more time, and the results are amazing!

I opened the Nero Drive Speed. It read 44x for the Yamaha F1 and 52x for the Sony CRX220E1. Let's leave the Yama alone.
For the Sony, I've set the read speed to 40x. This is the conventional setting found as the default for many readers. At least, both my DVD/CD ones have 40x as the maximum.
The spindown time is set to 2 mins.

Now, it's turn of the CD Speed.
The CD Quality Test gave perfect result. Just perfect!
Same - for the Scan Disk: no damaged sectors whatsoever:
Starting surface scan
Good: 100.00 %
Damaged: 0.00 %
Unreadable: 0.00 %
Surface scan completed[:0]

This makes me asking about the wisdom of the question "How do you write a CDR?". Should I ask "How would you read the CDR?!".[:p]

(in reply to john)

With the F1 you don't have to keep pressing the Eject button to reach the Maximum Speed it is all done for you automaticly unlike the Sony which you have keep pressing the eject button to reach Maximum Speed which is a pain in the butt !!!
