A stylus imitates a cutting head. Why would it not try to cut a groove on a blank test disc?
No, a playback stylus does not "imitate" a cutting head. It’s true that modern stylus profiles do come close to replicating that of the cutting head, but that’s pretty much where the similarity ends. For example, the cutting head is driven by an amplifier, and subject to cooling to offset the heat that results from cutting the disc.
Please don’t make me laugh, admit you got a bit hot ... Any neutrals out there wish to give cleeds a “pronouncement” with their findings to save him the bother?
It looks like you want to make this personal and argumentative. That's unfortunate. Have a nice day.
