Abstract
A loop-shaped drive and drive system for retrieving and storing information on flexible recording strips. The drive has a loop-shaped conduit having a working surface on its inner periphery. A fluid, such as air, is supplied to the conduit and emerges from an array of uniformly distributed orifices in the working surface. Fluid streams from the orifices support the recording strip above the working surface and transport it around the inner periphery of the loop-shaped conduit. As the strip travels around the loop-shaped conduit, it passes in close proximity with at least one transducer, thereby allowing the transducer(s) to read/write information on the strip.
