I'd like to learn everything I can about the lead-in area (which contains PFI, etc).
I'm working with a very thin mini-CD that seems to work about 50% of the time in some of the newer drives. It was more reliable in older drives.
Currently, I can put it in a drive and sometimes it'll recognize it as a CD and sometimes it can't tell. Eventually, after multiple tries, it'll work. I'd like to get this percentage of success up to a greater degree and so I was wondering if there's a problem with the lead-in.
I had the company that stamps the CD to check it out on their diagnostic machine. This thing costs around a million bucks. It says the discs are 100% correct. However, I'm still having this problem, so I'm trying to figure out what's different with the newer drives.
I was wondering if I were to relocate the lead-in slightly, would it possibly be in a more readable area, or if there is error recovery areas that I can place in the lead-in, to push the PFI and other stuff further a bit, so that they're more readable by the newer drives.
Anyway, I know this isn't the type of thing that usually gets asked, but since the drive manufacturers aren't real cooperative, I was trying to figure out how to solve this problem.
