Bought a 50 cake of RiDisc media yesterday. They have a lighter blue label with a greenish tinge to it. The media code is CMCMAG_AE1.
Burned two discs one at 8x and one at 4x. Both didn’t even get recognised as DVDs by my Panasonic standalone. They read ok in the DVD burner (Pioneer DVR-108 with 1.20 firmware) but in my Benq DVD-ROM drive the disc reading speed drops down to under 2x. I did some tests using DVDInfo Pro and noticed an alarming increase in parity error rates. Also double-checked by burning a disc using some of the older dark blue label stock I have left. No problems here and low error rates on scans, so it’s definitely these new discs.
Had purple ones a while back, then the dark blue ones which both had the MCC02RG20 media code and then the silver matte finish printable ones that were CMCMAG_AE1 media code; never had any problems with any of the RiDisc brand until yesterday.
These discs have a silver inner ring and a silver outer edge ring on the burn side; the previous incarnations only had the inside ring. Quality of the spindle has deteriorated too, they’ve used thinner plastic. I’ve also noticed a rougher end edge quality on the discs themselves.
Now I’m hearing rumblings about Verbatim discs going down the Ritek route!
I wonder if the market for blank discs is slowing to the stage they’re relying on cheaper grade material so they can keep in business.
