Abstract: A method for adjusting a tape wrap angle is described comprising the steps of operating the tape system to generate or regenerate an electrical signal in the head from the tape, either increasing or reducing the tape wrap angle as appropriate until a signal from the tape head reappears or goes to zero, then increasing the wrap angle until the desired angle is achieved as measured by the signal from the head or by moving the tape support a fixed amount. A tape recording and/or reading system with adjustable wrap angles is described which can be used with a method of the invention. The system includes one or more rollers mounted on an adjustable shaft with an eccentric or axially offset portion supporting the roller. Preferably for a magnetic head, an adjustable shaft and roller are located on the tape-in and tape-out side of the tape head. The angular orientation of the eccentric shaft is adjustable, thereby, allowing precise adjustment of the position of the roller with respect to the tape head. Rotating the shaft moves the eccentric portion of the shaft further behind or closer to the head and, therefore, causes the roller mounted on the eccentric portion of the shaft to move similarly resulting in a change in the corresponding wrap angle of the tape in relation to the head. When the desired wrap angle is achieved, the shaft can be restrained from further rotation by an appropriate friction or other locking means. Although the invention can be used with any type of tape head, it is used to particular advantage with flat contour tape recording heads.

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 that has textured surface over which the tape passes. The textured surface has a surface roughness exceeding the flying height of the tape above the surface. This new irregular surface topography reduces the air bearing and allows limited contact between the tape guide and the tape while minimizing tape distortion that can occur with other surface topographies.

Abstract: A tape drive is provided having a pair of stationary guide assemblies disposed symmetrically about the magnetic read/write head. Each of the stationary guide assemblies has a mounting portion and a separate guide surface portion mounted on the mounting portion. The mounting portion may be made of a plastic and the guide surface portion of a ceramic, for example. A spring arrangement with pressure pads is mounted directly on the mounting portion, and applies pressure to a top edge of a tape during guiding of the tape.

Abstract: A roller body receives a tape at a cylindrical surface. First and second flange members are located adjacent one and the other ends of the roller body for movement in the axial direction of the roller body, respectively. If one edge of the tape creases, the movement of the first flange member is restrained, so that a reference position can be set for the other edge of the tape in the first flange member. If the other edge of the tape creases, the movement of the second flange member is restrained, so that a reference position can be set for the one edge of the tape in the second flange member. In either case, the centerline can be prevented from shifting. Employment of the guide roller of this type in a tape drive allows a head to reliably follow a servo track on the tape.

Abstract: The invention is directed to arrangements of tape guides which can improve the guiding of data storage tape. Tape guides having specific sizes relative to the data storage tape are also disclosed. The disclosed tape guides and arrangements of tape guides can improve the ability to properly guide the data storage tape, e.g., during media fabrication, servo recording or readout, data recording or data readout. The invention is particularly useful for magnetic tape, but may also find application with optical tape, holographic tape, or other formats of data storage tape.

Abstract: A tape path roller guide has a cylindrical guiding surface between two flanges. A plurality of continuous venting valleys in the guiding surface are wholly parallel to a central axis of the cylinder forming axial paddle-like surfaces generating air flow away from the cylindrical guiding surface tending to draw air from the guiding surface. Thus, a tape is allowed to stay in contact with the guiding surface. Because of the continuous venting valleys, the roller cylinder is made by molding or extrusion.
