I’ve been buying the Memorex 4X at Future Shop and they have always been RICOHJPN up to now, the last batch is CMC. I need to know if the qua;ity of the CMC is as bad as I’ve heard.

Thanks
Sid

CMC quality has been pretty good for both 4x (F01) and 8x (E01) media.

CMC F01 burns fine in BenQ DW1620. Not as well as Ricoh R01, but well within acceptable error rates. I’ve attached two typical scans, both burned at 8x. I get more PIFs with some 8x media (MAXELL002 and SONYD11) than with 4x CMC F01 oversped to 8x.

Thanks I’ll do a few burns and see how they turn out.

My Lite-On LDW-451S couldn’t burn a CMC Magnetics disc to saves it own life but my NEC absolutely loved them. It looks like the BenQ does a nice job with them as well. From the burns I’ve seen from those two burners it looks like CMC Magnetics is pretty much up to par quality wise and can compete with Ridata on that level. I’ve actually been thinking about buying a couple 50 packs of HP 8x DVD+R’s which I believe are CMC Magnetics E01 media code. I had one that I got with my NEC ND2510A when I bought it and it burned off flawlessly at 8x and playback on stand-alone units was awesome. :slight_smile:

I found CMC F01 media to be almost unusable in my DW800a, to the point where 23 out of 25 got discarded. They were KHypermedia-branded, so they probably weren’t Grade A, which was surely a factor.

Unbranded Ritek Ridata 4x (RICOHJPN01) from blankmedia.ca burns beautifully by comparison and has a better reputation.

I’m pretty much exclusively sold on Ritek, Mitsubishi Chemical and Taiyo Yuden as a result. Buying bulk unbranded media from blankmedia is very competitive with buying retail product of unknown provenance.

Comparative results, the PI numbers are double of what they were with the RICOHJPN. I guess the results are acceptable. I updated the firmware since I burnt the last disc, I wonder if that made any difference.
