[http://vimeo.com/24946684]< Above link. It must what they used to make the vinyl itself. Your other colored records must be of higher quality than this one. I don't recall seeing one like this. Another guess would be the red part doesn't let that side of the die close enough do to being a harder material, but it's hard to imagine the die would be bothered by that. The dies must have enough pressure,and strength to keep it flat, pressing it equally. So, I can't keep from thinking it's the quality of the vinyl.
Vinyl composition effect on noise floor
So here's a curious thing I noticed today. Red vinyl is noisier than black! Ok, that's not true exactly, but check this out. I have a record that's half red, half black. I noticed after cueing up the record but before the music started that there was a distinct increase in the level of background noise when the stylus traveled into and through the red half, then a decrease when it went back to the black.
So, what would cause this? Because it's the same record, everything about the two halves must be the same... same master, same stamper, same pressing equipment, same packaging, same cleaning before I played it, same stylus in the groove, etc. Everything, that is, except the composition of the vinyl itself. Now, I know full well that color has nothing to do with it; I've got several very quiet colored discs and several noisy black ones. But I hadn't considered before that the makeup of the raw vinyl itself could be this important to a quiet background. Makes me want to get more info from pressing plants about how they source their vinyl. Thoughts?
Here's a video of the record spinning so you can see for yourself. Please excuse the poor quality, and turn up your speakers. http://vimeo.com/24946684
