Notes on the Concord/Panasonic 12 I.P.S. 1/2" reel to reel... This is an odd 1/2" recording format that was incompatible with other E.I.A.J., Shibaden, and Sony CV machines. With the transport speed of 12 inches per second (much faster that the commonly used 7.5 inches per second scheme), a "normal" one-hour length of videotape (as used on other 1/2" reel to reel decks) would only last around 40 minutes. There appeared to be no advantage to this higher linear speed in so much as video or audio quality improvement.
As with other non-E.I.A.J. machines, re-production and recovery of this format’s recordings is extremely difficult.
