Hi, Brandon,

Same technology.  The box I have that held the blank disc is labelled Grey
Flexograph."  I think "Audograph" is the name of the machine.  Or, things
changed over the years.

Steve,

Perhaps a silly question..

Like Shai, I understand these to be Audograph discs. Is the Flexopgraph an
altogether different technology or name of the machine that committed
information to Audograph discs? 

Thanks,
Brandon

These are dictation discs for the Gray Flexograph.

They are constant linear speed and require a special playback machine.  When
played on an ordinary turntable, they appear to start at one speed and end
up at a way different one.

I have the machine and have transferred quite a number of these.

Happy New Year, everyone.

A fellow Cornell Library employee just asked me what I might know the type
of disks they just found a stack of in a box of archival submissions (french
lessons?).  Short of my experience with cereal box records as a kid and
magazine inserts later in life, not much.  Here are some photos.

Without looking closely, I'm guessing that they play inside to out, based on
the blank material on the outside of some of them.  And that the technology
enabled multiple but independent tracks, i.e. that don't necessarily play
one after the other.  The keyed spindle must prevent these lightweight discs
from slipping.  The few disks I looked at are only one-sided, but there are
designations of "1" and "2" cut into them.

Anyone have a machine made to play these?  Would it be foolish to try with a
standard turntable (after some closer inspection of the groove to make sure
it doesn't require the turntable to revolve in the other direction)?

As always, I'm grateful for the community to consult here!
