"Prodisc is like Ritek: They make some good media, but also sell terrible crap."
"I've ritek type 7 12X that works at 40X and kodak gold 8X that works at 40 and sometimes 48X....."
"Ritek makes different qualities. The ones you find in TDK 16x seem to be very high quality, while Intenso-Ritek are CMC equal.
I prefer cyanine not because it's "cyanine", but because Taiyo Yuden makes very good cynine discs. If they made phthalos, I'd use them, too. Feurio tells you the type
"Ritek Type 1 / 2, made in 1999, seem to be very good (look into the c1 scans in my signature), while some Type 5 or 7 are said to be crap, but i didn't get type 5 or 7... "
"Usually Building E made better quality cdr like tdk and imation and other oem brand, but this is not always case sometimes
manufacure line may get into some trouble and product lots
of crap disk. Building H made better Phalocyanine disk(rumor?) while Building J and L made common cdr...remember just rumor.
Besides when you care cd quality you must consider your cd writer. For example I burn CD pro(Ritek made) disk with Liteon and Plextor, Plextor has fewer c1 error. In my personal opinion Dye type is not the question it depends on how much $$ you want to buy a cdr."
"I have a 100 pack of TDK's 32x media from compusa here in the U.S. and they are ritek. I was surprised. I don't consider ritek very good media as most of their media is crap after a few months. They are very sensitive to light, too."
"Don't use 40x certified TDK-Ritek, but 32x certified TDK, made by TDK. They're better and work well at 48x."
"Ritek is not bad, but it's nothing compared to original "TDK Reflex" or Taiyo Yuden. At least here in Germany, you get very different types of ritek. While tdk labeled ones usually are ok, intenso labeled ones seem to be as bad as cmc."
"Ritek: Fujifilm branded ritek was the old green/blue cyanine type which is only around average quality. Will not handle writespeeds higher than 20X very well.2
"I have first generation ritek cdrs which burnt at full speed, read at full speed, but after 1 week, produced many errors, and after 2 months were completely un-usable and were beyond recovery.
I had first generation cd's from CMC magnetics which have lasted for 6 years and can only be read at about 24X.
I prefer discs which can be read at low speed, but have a high degree of data security over cd's that can be read @high speed, but disintegrate quickly."
"If you use TDK D-view disc's then it's another case. Only the D-view disc's made by Taiyo Yuden are okay. All the others (TDK, Ritek) are not that good"
"However are you shure that TDK only buys A grade disc's because ther D-view line(mostly made by TDK and Ritek) scores prety poor. Also the own disc's of Sony score prety poor. The Mitsui and TY of Sony score excellent but there own disc's aren't that great. If Memorex buys B-graded Riteks then why do these b-graded Memorex riteks score any time better as your supposed A graded TDK's. "
How does one distinguish the high and low quality Ritek media, rjw ?
You can't see this direct. However if you look at some profesional(CD analyzer) test results you will find out that some retailers score allways score very good with there Ritek disc's. While some other retailers score prety poor. This is not based on a single disc or on a single batch or based upon one burners results. This would indicate that some manufacturers do get batches which are of higher quality (A-graded ones) while other use the b-graded ones. Now a lot of people would say hey a reatailer can change the quality rules and use the higher ones. However at this moment there is now indication that this happening. This won't be the first time that a company has different quality rules for there disc's and that the best disc's are used for the bigger names. Mitsui/Prodisc have done this or are still doing it. So now the next question is which Riteks manufactured disc's scored good and which scored bad.
Poor: Philips, TDK D-View, Traxdata, Arrita
Medium range: Emtec(formally known as BASF)
Allways GOOD: Memorex, TDK Reflex, Lite On
"Some Riteks disc's are and some are not. The problem with Ritek is that the quality varies to much. Good Ritek's are most times used Memorex, TDK. Bad Ritek's are most times used by Arrita, Philips, TDK (D-View). TY and Mitsui allways score above average in any test. The Ritek disc's are sometimes the winners but also sometimes one of the worst disc's.
"Still there is a lot of difference between the Ritek disc's. Some Dutch & German magazines tested some brands who used Ritek as manufacturer and
Some where very good (2nd place) even after some long time and some were bad even in the begining. Now most of these tests where done with just the 16/10/40A Plextor and drives. A drive that normally scores very high on writing quality. Others used a combination of a plex 24/10/40A , a lite on 24102B and a Acer drive. The acer seems to be having more problems then the other 2 with most media. But the Ritek philips media scored bad on all 3 burners so it isn't that good. The Memorex Ritek's did fine with all 3 drives. Now if I look through all my testresults I see that the companies (TDK REFLEX,MEMOREX)who have scored good with the Ritek disc's in one test also scored good in the other tests. (Now this might be the case that most tesing is done with the same model of writers. But then still the triple writer tests gives most times the same results.)
Now the compannies(philips, TDK dview) who scored bad in one test also scored bad in most other tests.
However this still doesn't say all except that Ritek makes disc's in different ranges of qualtity.
"I don't think so that much used says anything about quality the problem with cd-r's is that it is hard and expensive to check how good they really are. Now Ritek is one of the number one companies a long with CMC magnetics. Now do these companies score overall great. Well the answer is no.
But why are they used much then ? Well there cheap and people can't really check the quality of cd-r's. So how's about makeing more profit with lower quality disc's. Most people don't care about quality but the high-end market does. (audio-studio's and hospitals, tv-studio's (The Dutch Studio's only use TY disc's.)So why do you think that disc's can exist like Mitsui gold of Emtec cd-r master. Which are 3-5 times the price of some white branded (MBIL ) cd. Personally I would use the best possible quality I could get. But then again it is your companny and if you wan't to make up more money without thinking about quality then you should do. However in that case you shouldn't even have asked here how good some media works. "
"A dutch magazine tested some Philips 16x (ritek) disc's and the disc's scored bad now Philips said that the batch was just some raw test batch and not a real batch so they would send a new batch. The new batch performs just a little bit better however still the results are bad. Philips says that no matter how bad the test results where that there disc's will work correct(in the future)
However after a half year the disc's are tested by 2 other magazines and give the same lame results. So know what does this say. Just one thing Philips is to lame to use the higher priced TY or Mitsui media( which other brands did use and score way ahead and are even cheaper as the Philips disc's) since most customers can't test it and the allready got a good name based on there old Mitsui/TY disc's. 2nd Point Interpretate the facts good. Now 9 of the 10 tests will fail because of bad interpretation. Most times people won't make any hard conclusion or the wrong conclusions. I personally think that CDR-info is the only site on the net who does testing of writers correct. "
"Now RITEK and TDK are strange compannies since the have disc's that score very good and disc's that score very bad.
Also can be concludded that Plextor and TEAC burners do perform overall better than most of there competitors. However the Lite On's perform very strong with Taiyo Yuden media"
