Someone asked me to look at this very expensive unit , but I

Not seen and model number unknown.
Apparently there is something called OPC that checks the material of

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 ?

Don't know if this is related to your situation but read it anyway.

I've only previously come across OPC meaning optical photo-conductor
surely this OPC means Optimum Power Control rather the Ole Process
Control

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.


I did a bit of reading up about the technology in and around
