This is Yuden000T02 burned at 12x. What are the jiggles? I attempted to remove them by installing different IDE drivers (didn’t do a thing), and changing BIOS IDE driving strength from normal to strong, and it also didn’t do a thing.
These jiggles exist on every disk from 2 different batches of the same media, with varying amounts at different burn speeds. But everyone else for the most part seems to have smooth fluid lines.
