One of the last US-designed products was the legendary IVC model 9000 VTR, considered by many experts to be the best analog VTR ever made. It used 2" tape, much like the 2" Quadruplex format, but using segmented helical scanning for the recording and playback of the video tracks (as opposed to 2" Quadruplex's transverse scanning). Vacuum column tape handling and modular plug in electronics made the machine a delight to work with, and the multi generation capability was exceptional. The IVC9000 was also the first production machine to fully meet the complex editing requirements of the PAL eight field sequence.
