[78-L] Groove spacing - groove width

[David Lennick]

Vitaphone discs were 16 inch (apparently some smaller ones were used for the 
songs in The Jazz Singer, which must have driven the projectionists to with 
they were octopussies). That size and speed became the basis for transcription 
discs by 1930. The original Vitaphone discs did indeed play for only 10 
minutes, so groove spacing and width could be wider.
