It's obviously not a CD.  It might be just a brown disk with scratches,
being sold as something unusual to the gullible.  Or it might be an optical
disk of some sort, but not all optical disks are CDs.

This. That disc has absolutely +nothing+ in common with a "CD", barring the
fact that it (apparently) uses a laser-ablation process to write pits /
bits onto a rotating medium. We should all know by now that the original
(redbook) 120mm optical CD was a joint project between Sony & Philips.
These folks may have been co-developing a similar technology, but any
association with the Sony / Philips product is pure fantasy.

So what do we have, here.. a confused but earnest dreamer with dollar signs
in his eyes, or an outright conman? Either way, hopefully he doesn't reel
in any suckers.. or dog forbid any Minnesota walleye. =/

Martin, "The Complete Compact Disc Player"
1987 0-13-159294-7

Both Philips (NV Philips Gloeilampenfabrieken) of the Netherlands and Japan's 
Sony
Corp. made individual contributions to the production of the compact disc and 
player.
Philips began efforts to develop a compact disc in 1969, but it required ten 
years of
effort before it could show the first working system to the European press.

Philips' contribution was the creation of a video disc system using tracking by
means of a laser beam. With this as a basis, Philips then developed a more 
compact
version for sound reproduction. Sony added to the technology through its 
research on
data coding and error correction circuitry. Without these advances by Sony, 
reproduction
of the audio signal would not have been possible. Error correction circuitry 
helps
to ensure correct reproduction of sound even when the compact disc is plagued 
with
fingerprints due to disc handling, dust, scratches on the discs, and defects 
occurring
during manufacturing.

Since Sony and Philips were the prime movers toward the compact disc format,
we can better appreciate their efforts as shown in the following timetable.

DEVELOPMENT OF THE COMPACT DISC: A HISTORICAL PERSPECTIVE

1928Harry Nyquist establishes mathematically that the sampling
rate of an analog audio waveform must be twice the highest
frequency of the wave being sampled.

1939Pulse code modulation invented by H. A. Reeves.

1969Philips Research Laboratories begins work on optical disc
recording of video, audio, and data.

1972First public demonstration of optical disc recording (VLP,
the future LaserVison

1973/74 Requirements established for video, audio, and data recording.
Philips' associate, Polygram, producer of first laser-read
discs becomes full participant.

1974Sony develops stationary-head digital audio recorder

1975Philips begins development of industrial disc mastering
equipment

1976Sony produces first digital audio disc system based on FM
video format. The disc rotated at 1800 rpm, supplied 30
minutes of music on one side, and used an optical readout
system.

1976Conception of small diameter (compact) disc defines digital
audio project parameters

1977Sony announces digital audio processor to be coupled with a
video tape recorder for 12-bit quantized, two-channel
recording and playback.

1977Sony creates the first consumer digital audio processor. It
was called the PCM-l and. it recorded digital pulse signals
on video cassettes

1977JVC develops its first pulse code modulation digital audio
processor. The company begins to provide professional
digital recording technologies used in recording studios
throughout the world.

1977In cooperation with NHK, Sony develops a digital audio
processor for use with a professional U-matic videocassette
recorder.

1977Sony markets the world's first consumer digital audio
processor for use with the Betamax home videocassette
recorder.


1977Sony makes available a digital audio disc system employing
a pulse code modulation direct recording method. The disc
rotated at 900 rpm and supplied 1 hour of recording and
playback per side. It used an optical readout system.

1978After further technological advances, Philips defines Compact
Disc as a digital audio system to reproduce one hour of
stereo sound on one side. Efforts continue to develop
commercially viable lasers, optics, ICs, disc mastering, and
production equipment.

1978The world's first broadcast of digitally recorded programs is
made through Japan's four major FM networks

1978Sony develops a long-playing digital audio disc system with
the disc rotating at 450 rpm. The unit used an optical
readout system and played 150 minutes per side.

1978Sony announces the development of a stationary-head digital
audio recorder using 1/4-inch tape

1979Philips shows working model of their Compact Disc player
to press at Eindhoven, The Netherlands. Five months later
and ten years after research began in Eindhoven, Sony signs
agreement to cooperate in further system development with
the aim of making Compact Disc the world standard for
digital audio.

1980Philips, Polygram, and Sony agree to Compact Disc System
and submit it to Digital Audio Disc Committee in Japan.

1980Sony announces the compact disc digital audio system,

Well, to start with, let's take the obvious:   14" is not "compact",
even for Andre the Giant.   The rest is rubbish.

Optical disks go way back to 1958 with Dr. David Gregg.

Somewhere in my collection I have the first three BSDI releases (I was a
very early customer).

The first two, 0.3.3 and 0.9.1 (IIRC), came out on DC-600s.

1.0 came out on CD-ROM.  Since the readers were so uncommon then, BSDI
took the unusual step of including a CD-ROM reader with it.  Apparently
the economics were that it was going to be cheaper to do that than
having to pay someone to keep manufacturing the DC-600 tapes.

I still have the 5.25" SCSI-1 drive around here somewhere, complete with
the little carrier tray that it required for the media.  (The Sun systems
of that era came with the same drive.)

tl:dr; somewhere around 1991 was the inflection point :-)

Sony.
They wrote a book about it.

This isn't "the first CD".

The only thing this has in common with them is digital recording
on a spiral track.

Apparently the seller has never heard of WORMs or knows the history of optical 
data recording.

It's obviously not a CD.  It might be just a brown disk with scratches, being 
sold as something unusual to the gullible.  Or it might be an optical disk of 
some sort, but not all optical disks are CDs.

I don't know if DEC was the first to publish software on CDROM; it certainly 
was fairly early.  I remember hearing that DEC was building a CD factory to be 
able to do so -- that apparently was before you could find people to do it for 
you.  I forgot the date; not long after audio CDs appeared.  The VMS License 
Manager was invented to deal with software on CDs, I think.
