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?
