These zinc Repeat-a-Voice, Echo, Rekordo, etc discs used an entirely
different premise than the plastic Victor Home Recording Discs which had
a narrow groove widened at the top by a rounded stylus. Those
occasionally have good recordings on them. The zinc discs would have
dimples lightly embossed lower in the groove by a regular steel needle
which was supposed to be the same one to play the record back.  They
never intended you to be able to play them later on.  You would really
reused them.  If you have them and an acoustical machine you can try
them out yourself and hear that they replay practically nothing. 
Shiffy, I first reported on these so long ago it appeared in Lenny
Kunstadt's Record Research magazine at least 35 years ago!
