I bought a spindle of gold-coloured 8x Plextor DVD+R with Taiyo Yuden T02 dye a couple of months ago. Since I own a NEC2500, I was unable to do any quality (read K-probe) testing.
After a while, I started doing some primitive K-probe scanning on my JLMS XJ-166 and found inconsistent error rates at about a quarter to half way the disc. See for yourself
Picture one is a scan of a Plextor NEC 2500 burn @8x with Herrie Beta 5 firmware;
Picture two is a scan of a Philips Ricoh JPNR02 NEC2500 burn @8x with Herrie Beta 5
I have already found out the following:
- Changing the 2500 to stock firmware gives comparable results
- I’m having bad results with multiple Plextor discs from different parts of the spindle of 50
- Since the Philips and Platinum Ricoh JPNR02 discs are burning excellently on my 2500, the problem should not be burner hardware related in my opinion.
Could this really be a bad batch of Taiyo Yuden media? Anyone feel like commenting?
