[u-u] OT: Video Disc Player and discs

[Giles Orr]

Hi Hugh.

You appear to be thinking of Laser Discs, which did indeed come in both
forms.  Please note that I'm talking about a Video Disc Player, which uses
a form of modified vinyl disc.  It appears to be entirely CAV, so it
shouldn't be an issue.  Might be worth looking at the Wikipedia article I
referenced.
