RE: arsclist Fw: [MLA-L] Help! What is this?



These are likely recordio disks! I just transferred some of these!
BECAREFUL these were meant to be played with a Quill stylus, and a
regular diamond or steel stylus will damage these! They have a very wide
groove and can be hard to find a proper needle. Then you have to use a
very light tracking force IE: .75 grams or less I found worked well.

 There seemed to be quite a few do it your self record formats out
there, I have run into several different type's so far, but these were
very hard to transcribe as they are not a standard size. The "hub" in
the middle is smaller then a 7" 45 or 12" 33 rpm disc, the arm on my
turntable would hit the end stop before it got to the end of the
recording. I had to rig my arm up to travel in that far, and set the
cartridge up at an angle to get the right geometry.

Perhaps someone from ARSC could enlighten this person from MLA?
This is probably a transcription disc, but I don't recall any such
machine in my past experience.

| A colleague of mine in the Baptist archives came to me with a 6-7"
| aluminum disc looking similar to a 45 RPM single. Instead  of the 1.5"
| hole in the center, there are three small holes arranged in a
| triangular pattern. Can anyone shed some light on what this might be.
