Very interesting first post of 2014. Thanks. I can't remember if the Ampex museum had an actual non-functional one or just a picture.
In any case it was fun to see one actually play..."tape".
The other article was also interesting. I do disagree with one of the opening statements, however. They said -
"the process involved in making a record took at least twelve hours". Perhaps to make a pressing, but certainly by that time there were instantaneous lacquer or other discs that could be cut and played back immediately. In fact, from any point, with a needle drop, which has always been the advantage of disc over linear storage media, to the very hard discs in our computers today.
Anyway, very fun stuff, but I wouldn't want to be too close to a Blattnerphone when it was rewinding!
