Re: [ARSCLIST] 30-track SoundScriber
I cannot believe the number of orphan formats.
If your FA-5395 is working and you're up to 15 passes on each tape,
you can do it by recording timecode plus two channels per pass. 30
channels was not widely used. In hunting logging recorders on eBay
for the last year or so, I've seen several (and have two) 40-channel
Dictaphone units (with a 20-channel 1/2-inch head assembly as well).
These 40-channel units had 40 audio channels and a separate timecode
track, but at 15/32 in/s I think the timecode was proprietary (I have
two readers) and not IRIG B, but I could be wrong.
These, while they have multi-channel heads were designed to only sum
the desired channels into one speaker for courtroom playback and did
not have individual outputs. I have determined it is possible to tap
individual outputs from each channel and feed them into a digitizer
-- I can probably cobble together 32 tracks without trying too hard
in my facility.
Obviously SoundScriber made a 30-track 1-inch version. Dictaphone I
think also made that configuration, but other suppliers of loggers
used 8-16-24-32-48-64 track configurations between 1/2- and 1-inch tape.
There are a few forensics labs that I am aware of their existence,
but do not know precisely who/where they are, that might be able to help.
Also, beware that not all 30-track heads would be created equal. For
example, what Dictaphone called 30 tracks was 30 tracks PLUS timecode
while it sounds as if your 30 track machine does not have a separate
Why would NASA have chosen this over an IRIG recorder? Cost? Perhaps
there were no mid-level IRIG machines at that point? When did IRIG
jump to 28 tracks on 1-inch tape?
Sorry I don't have a good answer for you, but I hope I've provided
some idea of the magnitude of the problem.
You're ahead of many of the other people I run into -- at least you
have a playback machine (however clumsy) that you can access these tapes with.
Do you have a dimensioned drawing of the tracks? That would be a
help. Do you know what speed these tapes were recorded at? (or how
many hours on X feet of tape?) I have started searching for a head for you.
I had www.TerrysRubberRollers.com make me new pressure rollers for
one of my Dictaphones when I thought I might lease it to someone
doing 9-11 911 tapes, but I think he found another solution.

There is a playback machine (Multi-Channel Reproducer Type FA-5395 by
SoundScriber - early sixties), but the machine only plays back track 1
(usually IRIG-B - timecode) and two other tracks of your choosing by
using a variable selector (mechanically moving two separate playback
heads independently of each other in position over desired tracks). I am
looking for a 30-track playback solution, or any information about
either previously mentioned machines.
