That sounds almost like you're describing some sort of error correction on a piece of vinyl... Such a two-tracked record could be played on a deck with a two-needle arm, the distance between needle tips equalling the distance between groove valleys. The advanced deck would be less susceptible to bumps *and* able to take the two signals and subtract noise from either, like a pair of chromosomes. Something like that could be "complete without surface noise"... :: Alex >My question is: has anyone made a record with two parallel grooves that >spiral inward between each other that have different tracks with the same >bpm that have the their cue points line up, such that if the needle skips >to the other track (the one in parallel, not one groove ahead or behind) >it is still in time and in sync?
