RiTEK S-Dye and LiteOn Burners

G’day all,

Yesterday (24/05/2003), I purchased some Sytech 80min Silver/Blue CD-R’s from Harvey Norman in Cannington, Western Australia. Here’s the ATIP information from SMART-BURN Media Check Simulator:

This Disc is designed for CD-RW/COMBO Drive Only.
Disc Type, Material = CD-R, Cyanine
ATIP Lead-in = 97m 15s 12f
Norminal Capacity = 702.83MB (79m 59s 73f)
Disc Manufacturer maybe = RiTEK S-dye
SMART-BURN Speed Limit = 32X

Now, I’ve made five CD Speed data discs and tested them in both KProbe 1.1.12 and CD Doctor 1.04 and I get C1 Max > 200 and if I read at maximum speed, I get C1 Max > 3000 and C2 Max > 100. Has anyone had the same problems with these discs? Looks like the G-Type and JS-Type discs are more compatible with LiteOn recorders.

Ritek makes several dye “types”, I’ve never seen anyone explain WTF they are. TG seems to be the best. Suggest you slow those ones down.

@rdgrimes: Yup, I know!

G-Type and S-Type are Cyanine.
J, JS, and TG-Types are Phthalocyanine.
I don’t know what K-Type is but I think it’s Phthalocyanine.

I’d love to get hold of some TG and K-Type RiTEKs, but I don’t know who sells them in Australia!

Hi, terminalvelocd !

Those Riteks Cyanine that I got are S-type too, but their ATIP is different (Traxdata Audio) :

This Disc is designed for Consumer Audio Recorder (Low Speed).
Disc Type, Material = CD-R, Cyanine
ATIP Lead-in = 97m 31s 01f
Norminal Capacity = 702.83MB (79m 59s 74f)
Disc Manufacturer maybe = RiTEK S-dye
SMART-BURN Speed Limit = 12X

G’day all,

Okay, I’ve found examples of different types of RiTEK’s in my collection.

TDK 74min/650Mb CD-R74 1x-8x:
RiTEK K-dye (Cyanine)
“E” production line

TDK 74min/650Mb CD-R74 1x-12x:
RiTEK K-dye (Cyanine)
“E” production line

TDK 74min/6560Mb CD-R74 1x-16x:
RiTEK K-dye (Cyanine)
“E” production line

TDK 80min/700Mb CD-R80 1x-16x:
RiTEK JS-dye (Phthalocyanine)
“J” production line

TDK 80min/700Mb CD-R80 Multispeed 48x

Unbranded 74min/650Mb 1x-12x
RiTEK S-dye (Cyanine, Type 1, 12x SMART-BURN)
“P”, “D”, and “K” production lines

Digitor 80min/700Mb 1x-40x
RiTEK JS-dye (Phthalocyanine)
“L” production line

Sytech “A-Grade” 80min/700Mb 1x-40x+
RiTEK S-dye (Cyanine, Type 2, 32x SMART-BURN)
Unknown production line, no serial code

Would love to know what everyone else has.

Terminalvelocd,

Here is on example, of the CDRs I am currently using. They are Maxell 40x 700MB CDR:

Smart-Burn INFO:
Disc Type, Material = CD-R, Phthalocyanine
ATIP Lead-in = 97m 15s 17f
Norminal Capacity = 702.82MB (79m 59s 70f)
Disc Manufacturer maybe = RiTEK,TG
Serial: RFD80M-XXXXX

Now what is this “production line” info., and what is the difference, between E, K, P, etc. Also, where did you get that information? And finally, this dye type, i.e. K, TG, T, etc., is that only for RiTEK, or for all different manufacturers. Thanks.

@SuperG: If you have a look at the serial numbers around the clear centre hubs of your RiTEK CD-R’s, the first letter in the string designates the production line.
