IBM 729 the tape reel. A 3/4 inch gap between records allowed the mechanism enough time to stop the tape. Initial tape speed was 75 inches per second (2.95 m/s) and recording density was 200 characters per inch, giving a transfer speed of 120 kbit/s. Later 729 models supported 556 and 800 characters/inch (transfer speed 480 kbit/s). At 200 characters per inch, a single 2400 foot tape could store the equivalent of some 50,000 punched cards (about 4,000,000 six-bit bytes, or 3 MByte). The 729 series was superseded by 9 track tape drives introduced with the IBM System/360. The IBM 729 I
Ohio State Route 729 east of SR 350 instead of ending in New Vienna as it does today). No major changes have occurred to the routing since then. Ohio State Route 729 State Route 729 (SR 729) is a state highway in central Ohio. The route runs from SR 73 and SR 350 in the community of Snow Hill, northwest of New Vienna to SR 323 north of Jeffersonville. SR 729 begins at an intersection with SR 73 and SR 350 in the Green Township, Clinton County community of Snow Hill. Routes 73 and 350 formed a concurrency northwest of the southern terminus; the
