1 inch type B videotape
From Wikipedia, the free encyclopedia
1 inch type B (designated Type B by SMPTE) is an open-reel videotape format developed by Bosch in Germany in 1976. It never saw much success outside Europe however, due to the format requiring an optional and costly digital framestore in addition to the normal analog timebase corrector to do any "trick-play" functions, such as still, or variable-speed playback.
This was due to the fact that, unlike 1 inch type C which recorded one field per helical track on the tape, Type B segmented each field on 5 0r 6 tracks per field according to whether it was a 525 or 625 line machine.
The tape speed allowed 96 minutes on a large reel, and used 2 R/P heads on the drum rotating at 9000 RPM.
The picture quality was excellent and record only as well as standard R/P machines and "Trick" machines and portable versions were marketed. BCN20, BCN40, BCN50 etc.
