As a related aside, I happened to have a scan of a Laserdisc cutting service 
flyer from the 1980's. They quote £395 for a acrylic RLV recordable Laserdisc, 
£595 for glass, and mention that a master disc using conventional cutting 
would normally average more than £2500.

RLV is apparently single-sided, unlike conventional discs. This particular 
cutter was made by the "Optical Disc Corporation of America".

Presumably CDs were in a similar sort of price bracket a few years after they 
became popular, as were DVDs?
