@azonenberg@ioc.exchange The format of the scan would probably be dictated by the scanning technology. Because you could "unwrap" grooves in software if you had to. Probably, it would be easiest to make a linear scan of the groove, maybe with a neighbor on either side for redundancy.
You could do some kind of constrained physics-based modelling, but it occurs to me that this makes characterizing new needle cartridges potentially difficult.

@azonenberg@ioc.exchange I guess you could extract the audio from the surface scan "perfectly" and then degrade it in some way consistent with the parameters extracted from the needle model, Then you could generate the needle model just by playing the reference record and comparing it to the master.
