Someone asked me to look at this very expensive unit , but I declined. Not seen and model number unknown. Apparently there is something called OPC that checks the material of the blank media. About 2 out of 10 attempts to record, it drops out at this OPC check stage, equally so for the 2 makes of disc he uses. As it is still useable I declined to look at something that may well end up worse, and I suggested he try some other makers discs. Any other advice ?

Interestingly, the most reliable recordable DVDs that I have found, are Tesco's own brand. On many occasions, where owners are having obscure recording issues, that couldn't possibly be related to the recording media (could they?), moving over to the Tesco discs, has provided a complete cure. Might be worth a try to see if their audio recordables, are as good ?
Ok I've never heard of it before obviously. But I would assume it is an a control found in every optical recording device and not unique to the device you reference.
Good read and it answered a couple questions that have been floating in the back of my head.
Why blank CDR media Branded as Music CDR exist and why it is more expensive.
What actually was going on in the power calibration part of the debugging information I sometimes read in K3B DVD/CD burner for Linux KDE desktop.
One thing though. The article states that stand alone CD burners need to use discs with special info encoded in the wobble on a blank CDR but I have never needed to use Music branded media in our Fostex stand alone studio burner.
Many makes take no notice of whether the disc is a genuine 'audio' one or not. A notable exception used to be burners from Philips. A friend of mine bought what appeared to be a brand new Philips disc to disc audio recorder, from a dealer at a radio rally. He paid silly money for it - a fiver as I recall. The dealer had a whole stack of them on his stand, and most were marked "will not record". My friend was not particularly bothered by this, as all he was interested in was the playback capability, which both fitted decks, have. However, when he got it home and tried it, using a CDR disc that he would normally use in his computer burner, it was apparent from the error message that he got, that it was not recording because there was something about the media that it didn't like. The next day, he popped into a HiFi shop that he passed on his way to one of his calls, and asked if they knew what the error message meant. The shop guy immediately told him that it was a question that he often got asked, particularly by people who had bought second-hand Philips units off ebay, and that all that was needed, was to use recording duty-paid discs, which said "audio" on them, and contained the digital watermark. He duly bought some, and when he got them home, the guy was quite right, and it recorded perfectly.
