Thanks for sharing those recordings, it was awesome to see the passion on restoring those wire recorders. I am very impressed with the audio quality, I would not claim to have golden ears, but I did not hear much flutter or audio distortion as you hear in other "older" mediums.
Hi there -- no, there's no policy against links -- the problem was that the link I had from last year no longer worked -- if you can email the link to me at max@CliveMaxfield.com I would be delighted to add it into the article :-)
I didnt know wire recorder existed either, until a colleague introduced it to me a few years back. Quite facinating.
Apparently you found my colleagues story but didn't include the link to his nice images and recordings. I assume some kind of policy prevents you?
I remember playing with an old Zenith spool audio recorder as our first consumer product that recorder family events (circa 1966), and appreciate the value of servo drive electronics that assisted in keeping the flutter to a minimum.
It is remarkable that any of this equipment still functional, given that most mechanism rely on friction and rubber mechanisms (which ages very fast) in order to feed and keep the media on track.
As a young student considering career options prior to attending college, I worked for AMPEX a audio and Video recorder manufacturer. As a technician doing final test and bias on their 64 track tape recorders, it sure was a niece lesson on audio and servo electronics. By today standards, the audio fidelity is great if not better, but some the mechanical limitations fall short to measure up with modern digital means to eliminate servo variations and other side effects of media drive. Progress has come a long way, but still in pursuit of a more durable media ;-)
