摘要： A method and apparatus for automatically applying a flying splicing tape to a roll of sheet material. The roll of sheet material is defined by a width and includes an outer-most layer. With this in mind, the method includes lifting a portion of the outer-most layer away from a remainder of the roll. The lifted portion is then cut to form a leading edge that is otherwise spaced from a remainder of the wound roll. To this end, the cut is made at a defined spacial location along the outer-most layer such that the leading edge is radially aligned with a defined application line relative to a circumference on the wound portion of the roll. In other words, when the outer-most portion is subsequently wound back onto the roll, the leading edge will be aligned with the defined application line. The splicing tape is then applied to the wound portion of the roll at the defined application line, such that the splicing tape extends across at least a portion of the width of the roll. In one preferred embodiment, the splicing tape is applied in a straight fashion relative to an axis of the roll. Finally, the leading edge is adhered to an outer surface of the splicing tape. More particularly, the leading edge is positioned relative to the splicing tape such that the outer-most layer covers a first section of the splicing tape, whereas a second section of the splicing tape remains exposed. In another preferred embodiment, the applied splicing tape is cut to form a trailing end that is substantially aligned with a side of the roll.

摘要： Methods and apparatus for applying a flying splicing tape to a roll of sheet material. A preferred embodiment of the invention provides methods and apparatus for lifting a portion of the outer-most layer of sheet material away from a roll of sheet material to form a lifted portion of the outer-most layer, applying a splicing tape to a wound portion of the roll, and applying pressure to the lifted portion of the outer-most layer to progressively place the lifted portion of the outer-most layer in contact with the remainder of the roll and the splicing tape.

摘要： A tape bearing surface for a tape that reduces tape surface contact near the edge, while minimizing variation in cross-web tension, and a method of making the same. The tape surface piece has a longitudinal axes defining a tape path and a lateral axis is perpendicular to the longitudinal axis along a top surface. The top surface defines a convex shape having at least one distinct radii extending along the lateral axis. In one embodiment, the convex shape is elliptical or parabolic. In one embodiment, two distinct radii are formed so that a first radius proximate a center of the lateral axis is greater then a second radius proximate edges of the lateral axis. The present invention is also directed to a tape guide and a tape cartridge containing the present tape bearing surface.

摘要： A tape cartridge includes a first rotatable hub and a second rotatable hub. The first hub and the second hub are wound so that they are substantially full of the flexible recording tape. The flexible tape between the first and second hub crosses a centerline including the two hubs. Both the first rotatable hub and the second rotatable hub are removable from the cartridge. The hubs have a flange with a conical edge which nests into a first opening and a second opening in the tape cartridge with conical receiving surfaces. The conical edges have a plurality of reliefs therein to form conical teeth within each of the first and second hub. The conical teeth of one of the hubs engages the reliefs of the other hub to seal the cartridge and to support the tape between the hubs. The cartridge also includes a base, a latch for engaging the first rotatable hub and the second rotatable hub. A cartridge cover covers the latch and base. The tape cartridge is placed into a tape drive for reading and writing to tape media within a tape cartridge. The tape drive includes an apparatus for removing the first hub and second hub from the tape cartridge. The tape drive also includes a first spindle attached to a first arm and a second spindle attached to a second arm. The arms move the first spindle and the second spindle between a hub receiving position and a functional position. In the functional position, the first spindle and the second spindle position the tape near the transducer in a transducing relationship. Each of the spindles may include a hub flange extension or a tape packer.

摘要： A data storage cartridge includes a length of magnetic tape wound on a pair of tape reels within a housing to define a tape path. A tape guide disposed along a portion of the tape path includes a top and bottom flange. Each flange is resilient so that it acts to resiliently guide an edge of the tape. This minimizes violent crashes of a tape edge against the tape guide. Each flange may have a plurality of spaced resilient finger guides for directly contacting the edges of the tape. The finger guides serve to independently exert a force on the edges of the tape, thereby guiding the tape.

摘要： A high performance tape reel with an outwardly facing cylindrical tape winding surface parallel to a drive pin bore on a reel hub. The hub has a pair of hub reference surfaces adjacent to the winding surface for aligning tape flanges. Flanges are attached to the hub at a location remote from the winding surface and magnetic tape. A drive cap with a reel pin bearing surface is attached to the hub so that the reel pin bearing surface substantially covers one entrance to the drive pin bore.

摘要： A reel-to-reel tape cartridge includes two tape guides for guiding the tape to and from respective tape reels. The tape guides have a large radius of curvature and are flanged to form a long trough to guide and align the tape to improve tape tracking. The tape guides are formed of two flange pieces separated by a tape surface piece and a post. Each flange piece is generally semi-circular and includes three notches which receive tabs on the tape surface piece to secure the tape surface piece. The tape surface piece is formed as a type of leaf spring that is loaded when it is assembled between the flange pieces. The post can be cylindrical or flat.

摘要： Data recording tape is passed along guides and past a read/write head. Sensors detect the position of the tape and adjust the guides and the head as a function of the position. If the tape deviates from the target tape path, a controller moves a guide to steer the tape back to the target tape path, using the sensor signals. In cases of tape disturbance such as those involving rapid tape motion, an adaptive estimator uses the sensor signals to position the head to anticipate the expected position of the tape when the disturbance arrives at the head.
