Abstract

In the figure, a low cost magnetographic printer 20 is shown which records at 400 inches per second and reduces meed to 31) inches per second for printing. A cylindrically shaped magnetic tape 10 is positioned over a hydrostatic air 3earing post 6 which is internally pressurized. The cylindrical tape is held on the post bv a fixed shoulder (not shown) on one end and a removable flange (not shown) on the other end. The air bearinq in the post suspends the tape circumferentially from the post and positions the tape accurately between the flange and shoulder by actions commonly referred to as "pneumatic bleed servo" (in reference to U.S. Patent 3,225,600).
