Dutch company operating a vinyl pressing, cassette duplicating and printing plant in Baarn. Active under this name from 1962 until 1979. It succeeded Philips Phonografische Industrie and was renamed to PRS Baarn in 1980.

How to identify vinyl:
670 in the runout area means the lacquer was cut in Baarn.
Phonodisc B.V. was a full service provider, an additional "Made in Holland" on the labels means the record was also pressed there.

Additionally, 1Y / 2Y, 1W / 2W or 1F / 2F, etc. before or after the 670 can be found. These codes are format identifiers:
E after the side identifier (1/2) stands for 7" EP 45 RPM (Mono or Stereo).
F after the side identifier (1/2) stands for 7" 45 RPM Mono.
L after the side identifier (1/2) stands for 12" 33 1/3 RPM Mono.
M after the side identifier (1/2) stands for 12" EP 45 RPM Stereo.
R after the side identifier (1/2) stands for 10" 33 1/3 RPM Mono.
T after the side identifier (1/2) stands for 7" 33 1/3 RPM Mono.
W after the side identifier (1/2) stands for 7" 45 RPM Stereo.
Y after the side identifier (1/2) stands for 12" Stereo (regardless the speed).

Mono releases cut on a mono lathe (for 25µm / 1mil stylus) can be identified by an upside down triangle (▽) on the labels. This symbol is absent from later mono releases cut on a stereo lathe.

Stereo releases can be identified by a symbol showing two overlapping circles on the labels. Originally both circles were shown in full; starting in 1976 a new design was introduced where the left circle partially hides the right circle. (It should be noted this is only the case for the Dutch branch, the Phonogram branches in other territories only introduced the design change at later dates.)
