Abstract: Provided are a tape guide roller and tape drive having a guide roller having magnets and bushings to stabilize a roller barrel for a tape medium. The tape guide roller has a roller barrel extending around a vertical axis. The tape medium passes across the roller barrel to guide the tape medium on a tape path. A plurality of magnets positioned with respect to the vertical axis provide an axial force to stabilize the tape guide roller axially.

Abstract: A rotatable tape guide with a cylindrical barrel having a cylindrical peripheral surface; and a guide flange substantially at each outer side of the cylindrical barrel and having a frusto-conical surface. The frusto-conical surface is configured at a taper angle outward with respect to the perpendicular direction from the cylindrical surface; the taper angle of the guide flange substantially at an angle such that the angle at which a tapered tangential line extends from the circumference of the cylindrical peripheral surface of the cylindrical barrel and along the taper of the guide flange, to the maximum periphery of the frusto-conical surface, is at the maximum potential angle of attack from a magnetic tape at a supply reel with respect to the guide flange.

Abstract: A tape guide roller comprises a cylindrical barrel with a cylindrical peripheral surface parallel to a central axis; the cylindrical peripheral surface comprising smooth cylindrical surface zones alternating in the circumferential direction about the cylindrical peripheral surface with non-smooth cylindrical surface zones. The non-smooth cylindrical surface zones may comprise a textured surface, and/or may comprise a grooved surface.

Abstract: A magnetic-tape cartridge case has the same general geometry and dimensions of a conventional cartridge, but an additional slanted wall is incorporated between two other walls at one end of the cartridge case. A memory chip is placed with its antenna adjacent to the additional wall inside the case. The memory chip is accessible by non-contact means from two substantially orthogonal directions and the antenna of the external reading device may be placed in closer proximity than heretofore possible and may be optimally oriented to improve data transmission.
