ROLLER GUIDE FOR MAGNETIC TAPE WITH MULTIPLE GUIDING SECTIONS |
摘要 |
A device for guiding a magnetic tape in a data storage drive including a cylindrical body rotatable about a longitudinal axis. The cylindrical body having opposing ends and defining a surface area for mating with a magnetic tape. A curved section at opposite ends of the cylindrical body is contiguous with the surface area of the cylindrical body. A plurality of vents in the cylindrical body allow air flow therethrough between the surface area and the tape. The amount of air flow between the cylindrical body and the tape produces varying frictional forces on the tape such that the tape is biased to a nominal position on the cylindrical body by air pressure on the tape resulting from the air flow interaction with the curved sections.
