Is Ricoh and Ritek the same thing?

[-jsl-]

Well, being color-blind I know that a color is a quite subjective thing.
It's highly unlikely that Ritek would use its own dye with RICOHJPN's media code including parameters describing the write power etc. It would give a poor writing quality as it would not be optimized so it would be simply stupid. I'm sure Ricoh would not like to have its manufacturer ID on those discs and Philips' Licensing would not like it either as all discs with the same mfr + type ID must have the same properties.

Here is the media code of a 2.4x DVD+R with Ritek mfr ID:

08 02 00 00 A1 0F 02 00 00 03 00 00 00 26 05 3F .............&.?
00 00 00 00 00 00 00 52 49 54 45 4B 00 00 00 52 .......RITEK...R
30 31 01 38 23 54 37 09 00 5A 65 00 AC 5F 14 14 01.8#T7..Ze.._..
0A 0A 0A 0A 01 19 1B 0B 0B 0E 0F 01 00 00 00 00 ................

and here is the media code of a 2.4x DVD+R with Ricoh mfr ID:

08 02 00 00 A1 0F 02 00 00 03 00 00 00 26 05 3F .............&.?
00 00 00 00 00 00 00 52 49 43 4F 48 4A 50 4E 52 .......RICOHJPNR
30 30 01 38 23 54 37 0C 00 50 6C 00 C8 66 16 18 00.8#T7..Pl..f..
0B 0B 0A 0B 01 19 1B 0B 0B 0E 0F 01 00 00 00 00 ................

as you could see they have quite different parameters regarding "the peak power multiplication factor used in the OPC algorithm", "bias/write power ratio used in the OPC algorithm" etc.

The sales manager from RITEK USA confirms that RITEK makes
the media for RICOH

this is how some RITEK media made by ritek bears the RICOH ids

This is current information although her name escapes me, I met her at tech expo NY (AUG 2003)

@ jsl ...after reading your post, it appears I misread the post regarding dye color. The original poster specified they had some Silver top Ritek disks as well..and the color was different from the Ritek/Ricoh disks. So it appears that the Ricoh/Ritek disks are the ones which are considered to have that tinge of blue. Of course, as I said..I am no artist...but that certainly isn't how i'd specify the color. It appears to me that the Ritek disks have a very nice looking deepish, yet lighter then the standard Azo dyes.

But that still seems very odd because I will tell you this..many people who purchase Ritek media are loyal Ritek purchasers. As you see, they get nutty from everything from the dye color to ridiculousness like serial numbers in the hub. With that being said...I find it very interesting that Ritek is actually selling Ricoh disks under their own name. Up until this point I have never read or heard of this before and it's seems peculiar. Putting quality aside for second..people who purchase Ritek disks expect Ritek disks...essentially...with these specific disks being mentioned..they aren't getting Ritek disks. This is the same scenario as Verbatim using CMC and saying the disks are Verbatim....that just isn't the case.

The truth is...the Ritek enthusiasts aren't getting actual Ritek disks in certain instances. This is something that I wouldn't be concerned with..but I know many would be concerned with.

Shifting gears for a second..you appear very knowledgable with media and moreso laser power. A poster sent me a link a while back to exactly what each line/number specified in a media id....and the difference between the two do appear to be the values you specify.

I am curious though...do you do any of this for a living? Because you sound very knowledgable, however, I remember asking a post question months ago regarding the Sony 4x burners being able to burn @8x. I thought there would be a possibility this would be the case, and you responded by saying there was absolutely no chance that would be possible. Just about two months ago .Sony confirmed what I had already believed, which was that there current burners can burn at a speed as much as 8x.

And here’s a quote from cdrinfo regarding the Sony technology.

Sony develops new laser diode promising 16X DVD recording.

Sony announced that a new 650nm semiconductor laser diode is currently developed, allowing DVD recording speeds up to 16X. First samples of the new "SLD1236VL" series are planned to be available by December 2003, while mass production will start in June 2004.

According to the company, current laser diodes used for Sony DVD recorders are capable of 8X recording.

Thank you for that info. That explains the post I made, which started this whole thread to begin with.

[RAAGAAman]

RAAGAAMAN Said:

I know for DVD+R/RW TerminalVeloCD is correct.
Ritek produces Ricoh media with their Stamper and material. Ricoh allows Ritek to sell media that was made with their process and stamper under the Ritek name. Ricoh takes the grade "A" media from Ritek's line to ship under their brand name. Ricoh did this because it is to expensive to produce media in Japan and it is easier to sub-contract this out.

I thought I said that somewhere up near the top.

@ RAAGAAman, oh, I figured you hid in your cave with all the mularky you were posting. I see you have the sack to still come out of your cave and post garbage. Your facts were all screwed up and what is it you are trying to prove now?

Thank goodness you aren't attempting to feed people more B.S. "MID" Man..lmao....so what is it you're trying to spew now? As far as dcsos goes...I've made my comments already. Everyone and their mother has spoken to someone from Ritek...real interesting to say the least..of course not a single person has a name of that person...nor can they explain why there are still plenty of people who have recently purchased Japan manufactured Ricoh disks. In addition, I find it more interesting that these so called facts weren't posted prior. After all..people have been talking about Ricoh and Ritek or Ricoh vs. Ritek for quite some time.

Go back in your cave.....there hasn't been a single solid fact from anyone in this post. But at least other posters didn't complete fabricate crap. By doing that you only confused and made yourself look bad. I would love to hear more fairytales though.

@defense,

I don't want to sound rude or start a bitter argument here, but exactly what or who are you trying to "defend"? It has been known for quite some time that RiTEK does produce discs (CD-R and DVD+R/W) for Ricoh that carry the Ricoh manufacturer's ID (RICOHJPNxx) or ATIP code (97:27s:6x or 97:48:0x). The Ricoh/RiTEK DVD+R/RW discs are distributed using a large number of brand names including TDK, Memorex, and RiTEK's own brands known as RiDATA and Arita. These RiTEK-made discs carry exactly the same serial numbering system as found on any recently made RiTEK CD-R or DVD-R/RW.

To back up my statements above, tompika has provided us with a nice picture of a new Ricoh/RiTEK 8x DVD+R for us to look at. Notice the small letters and numbers printed in black that closely hugs the hole at the centre of the disc? This is RiTEK's serial numbering system used on most if not all of their recently produced discs. I have used CDs and DVDs from many different manufacturers and I have never seen any other manufacturer's discs that use a numbering system identical to RiTEK's. The closest I've seen so far is the numbering system used by Sony's OEM DVD-R producer in Austria, however the font is slightly difference and the sequence of characters/numbers is different.

As far as I know, the list given by -jsl- is accurate. The Ricoh discs that are Made in Japan are rare outside of Asia. The DVD+Rs with the RiTEK manufacturer's ID are also rare. As mentioned by many before, an overwhelming majority of RiTEK DVD+R/RWs carry the RICOHJPNxx manufacturer's ID.

Of course you could do some further research by comparing packagin (e.g. jewel case/cakebox styles, wrapping/packaging styles, etc.), but you will eventually find that everything will lead to RiTEK as being the original equipment manufacturer. Not that there is anything bad about that. RiTEK and Ricoh have been known to make excellent quality media and it is my opinion that RiTEK-made Ricoh discs will continue to be winners on the market because of the ability of both companies to keep quality standards high while keeping costs low. A real win-win situation for both the manufacturers and the consumers.

There's no need to cause a big fuss over this matter. My advice: go buy some discs and get burning!

[EDIT]Why are people saying that Ricoh make discs for RiTEK? RiTEK has many more production lines and therefore have the capability of producing many more discs than Ricoh themselves are capable of.

CD Media World has reported in the past that RiTEK has purchased Ricoh's production plant in Japan. See the article here:

@ TerminalVeloCd..are you actually reading the stuff you are posting links to? It's obvious from your variations in your posts..your really searching hard. Please read the link you sent. First, it doesn't make mention of a single thing about Ricoh/Ritek DVDRs. It specified CDRs...if it were referring to media..wouldn't it just be easier to say media? Of course it would..it specified several times "CDR" media. For the fifth time...I never said a thing about CDR media.

I admitted on one of my first posts...I would of thought it would be the other way around....but clearly Ritek produces media for Ricoh...but they do NOT produce ALL media. I also never said they did or did NOT manufacturer certain 8x disks...I asked the question to make a point. Which was can ANYONE honestly say that they know for a fact or produce ANY info which backs up much of the overexaggerated info they've posted. And again, i've still not seen a single fact.

And as far as facts go..that article was in September of 2001, referred specifically to CDR MEDIA..AND FURTHERMORE DID NOT..I repeat did NOT say that RITEK actually purchased that one "PARTICULAR" plant. It said they were in NEGOTIATIANS to purchase the plant. It also specified more NEGOTIATIANS with CMC considering one of MCC plants in IRELAND.

Neither specified a sale and actual transaction between the two corps. In addition, if you read RAAGAMAN's posts..they are filled with pure speculation and more inaccurate information on various topics. Get a load of the "MID" garbage. The funny thing there is that I misread the dye color post and initially thought the dye used on the Ricoh/Ritek dye was "RITEK's." But last but not least...what makes me smirk more is how everyone and their mother has spoken to someone from Ritek...a friend..a relative..their best Man at their wedding....of course, not a single name or contact number has been posted.

I find that a little peculiar..especially when there have been numerous discussions with Ricoh and Ritek in various posts. What caught my attention with this post was that Ritek disks actually had a RICOH manufacturer id. As I said...because those disks are using Ricoh's dye and production process...that would absolutely irk some of the loayl Ritek Aficionados.

Yes, I am reading the material I'm posting links to, and yes I realise that the link to the CD Media World was referring to CD-R media. Remember that DVD+R/RW first appeared not long before this article was written, and manufacturers back then were concentrating their efforts on CD-R/RW production. I know the article ísn't a recent one, but it does give information about the leadup to the current situation.

I NEVER said that RiTEK did not produce certain 8x discs - I was purely giving an example of how the RiTEK numbering system works/looks like.

The FACTS are right in front of our faces. I refer back to my last post regarding the RiTEK serial numbering system and how dissimilar it is from other manufacturer's disc numbering systems. Obviously you can't face the FACTS???

HOWEVER, it DID say that RiTEK has been working with Ricoh by supplying OEM media for some time.

Pure speculation? I don't think so. It's not as if we don't have the products right in front of our faces to observe and compare. You will find that a few people have in the past contacted Ricoh for information regarding the production of their CD/DVD media and have confirmed that RiTEK does indeed produce a lot of Ricoh's media. Like I said in my previous post, the list of media given by -jsl- is accurate, and if you do not agree with these findings, I encourage you to do some research to find out for yourself.

@Terminal...this will be my last post on this subject..because it's obvious this is going nowhere. What part of "I SAID RITEK DOES MANUFACTURE "SOME" OF RICOH's media" do you NOT understand? You have no knowledge of any of these processes as you and your buddy RaagaMan attempt to imply. You are nothing more then a "GOOGLE SEARCHER" who is trying to pass info off as if you have a clue. At least you haven't completely fabricated fairy tales like Raaga.....but your links are completely worthless. You mine as well link to ...
http://www.pizzahut.com/

because your links are completely cheesy. Nothing...and I do mean NOTHING you've linked has any credence....and it's obvious you continue to search google at your every chance to pull things up. How bout linking something with some facts for a change? That last link SPECIFIED CDR MEDIA AND DID SO SEVERAL TIMES. And the truth is...with that one particular plant..you have NO CLUE whether or not that transaction was ever executed. Just stop with the B.S man.....and if you are gonna quote me...FIRST..read my posts...and second..get the quote function right. It really isn't all that difficult. You've got google down..so getting the quote function on this forum down should be cake.

Now if you can post a link to ANYTHING factual which says that Ritek manufacturs EVERY SINGLE RICOH disk, then do so. If not, stop while you're behind because I said days ago that it was clear Ricoh was manufacturing disks for Ritek...after I initially would of thought it were otherwise.

[vitualis]

Surely this argument is over??

It looks like Ritek produces a lot of if not most of Ricoh IDed discs -- but probably not all.
