Generally all the necessary ingredients for different vacuum-coating processes were present long before the

production (1902–1912), a vacuum coating process (“electrical evaporation,” “cathodic disintegration” or, as it
- q4 A! m0 p1 d4 wwas later called, “sputtering”) was the “enabling technology” that allowed mass production of the records. In
2 u# y, S# U: f" Vother cases the use of vacuum coating processes has supplanted the use of other coating processes, such as8 L- L0 `! j# u H8 U3 O) w2 o
electroplating, with a more environmentally friendly process. In still other cases the existence of vacuum coating0 l3 O0 I# B5 p$ C' n: q0 g( j
