You probably meant 200 ips "Inches per second" which is a fast drive. As were those big IBM's. Most normal 9-track tape drives ranged from 45ips in the mid to late 70's to 125ips in the early to late 80's.
I'm fairly sure it was frames per inch. The more modern "PE" 9-tracks were up in the 6250-FPI range, if memory serves. The 7-track units were used with an incremental data logger that would write 1 frame at a time, the tape was moved with a stepper motor. It was read with a conventional high-speed (sort of) block read transport. The 7-track 200-FPI tapes are mention here: http://www.learn-about-electronics.com/magnetic-tape-storage.html Regards, Lew -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
