Hi Greg, I am certain that you have seen the grooves on a regular 78 rpm record. These are about the same size as a 4 minute cylinder grooves. Have you ever seen a Pathe record that is played with a Ball stylus? These are close to the size of a two minute record.
On a 4 minute the grooves are 200 per inch and you cannot clearly see the groove bottoms, with a two minute record the grooves are 100 per inch and you can clearly see the bottom of the groove where the sound is. If anyone does not agree, please let me know.
