O YOU know what causes the scratch
or surface noise common to ordinary
phonograph records—and why you never
hear it in a Columbia Record?
' Then split an ordinary phonograph record
* in two—so that you can get a good look at
*he inside of it — and you'll see the reason.
It's made of what is known as "solid stock"
i —the core and the playing surface are made
of the same material. The shellac and other
!» materials needed to make the playing surface
are mixed all through the record. These
materials are pressed together under heavy
Ijvdraulic pressure.

Consequently, when the
pressure is released, the
fibrous material on the
surface of the record ex-
pands — and that's what
causes hissing and surface
scratch when you play it. The older the rec-
ord, the greater the expansion of the fibre,
and the more hissing and scratching.
Now examine the illustration above. It
shows how Columbia's "Laminated Process"
not only gives the record greater tensile
strength—it proves how this exclusive
Columbia Process absolutely prevents ob-
jectionable surface noise and scratching.
First a core of tough, fibrous substance.
Then, on each side, a layer of especially
prepared paper. On this paper is built
Columbia's playing surface of shellac and
other ingredients.
No fibrous particles can work from the
core to the playing surface of a Columbia
Record to cause surface scratch—because
Columbia's playing surface is pure playing
surface, insulated by the paper layers from
the core containing the fibrous material. No
other record is made like it!
And no other record sounds like it!
