information. If the groove width logistics board encounters high-energy, low-frequency sound, the groove will
temporarily be cut wider. The cutting head moves horizontally, in a straight line. However, almost all playback
turntables use a stationary, pivoting tone arm, which induces phase distortion during playback.
The RIAA curve is added during the cutting process–it has crucial impact on the signal being cut to the disk. The
Abbey Road VMS-80 RIAA curve was precisely modeled, as was a slight modulation due to the spinning engine of
the VMS-80.
2. The pressing plant:
The press process has the biggest impact on sound, and plays a big role in what we call the “vinyl sound.” It increases
the noise level and adds crackling to the sound.
a. Master acetate
At the end of the cutting process, the 14” acetate is the considered the master. An acetate is a piece of aluminum
coated with a layer of vinyl, into which grooves are cut, like a record.
b. The “Father”
The master is sent to the pressing plant, where it is plated by silver and then electroplated with nickel. This
creates the “Father.”
c. The “Mother”
The father is then oxidized and plated once again. The result is a metal plate that when separated from the father
can be played back on a turntable to check for errors. This is called a “Mother.” The mother is used to create the
“Stampers.”
