Is this true?
Is this why First Run discs almost always fly different than the Production runs?
Is this how "Night-Shift" discs were made? Did they run out of regular plastic and try and pull a fast one and use the "Filler" plastic.
Thanks for answering those questions that I'm sure keeps someone somewhere awake at night.
Not true at all. As for first runs being different. It happens sometimes and not others. Different runs may be run with different material batches and therefor might be different or not. On the other hand, there might be something to a brand new mold that does something different, that disappears over time, like the record grooves that are sometimes there. If this is the case, I can't explain it.
