sootshe Posted September 20, 2020 Share Posted September 20, 2020 The stylus should't be hitting the bottom of the groove. 1 Quote Link to comment Share on other sites More sharing options...
Schu Posted September 21, 2020 Share Posted September 21, 2020 The issue I see is that it relies on physical movement to generate an electrical signal... where the information resides. Quote Link to comment Share on other sites More sharing options...
BadChile Posted September 22, 2020 Share Posted September 22, 2020 I seem to recall from my understanding of stereo playback of the vinyl medium that it is labelled incorrectly. My understanding is that one side of the groove is based on the addition of the left + right channel (L+R) and the other side is based on the subtraction of the right channel from the left (L-R).

BING!! Quite honestly, I'm surprised it took so long for someone to answer this correctly, especially since there are so many vinyl enthusiasts around here. And to take this one step further, there is also a vertical component - for both L & R channels. The stylus has to track up & down as well as scanning the L & R walls of the groove in order to achieve the L+R/L-R component. Quote Link to comment Share on other sites More sharing options...
Edgar Posted September 26, 2020 Share Posted September 26, 2020 Um, that's not how I read the RIAA specification, http://www.aardvarkmastering.com/riaa.htm (emphasis added): 1. The stereophonic groove shall contain two channels of information recorded as orthogonal modulations of a single groove. 2. The 45 degree-45 degree system is the standard. In this system the two mutually perpendicular axes of modulation shall be symmetrically disposed with respect to a normal to the disc surface. 3. The right hand information channel, as viewed by the listener, shall appear as modulation of the out side wall of the groove. 4. When equal in-phase signals are recorded in the two channels they shall result in lateral modulation of the stereophonic groove shall produce equal in-phase acoustical signals.
