摘要： At a reel, an outer peripheral surface of a cylindrical tube portion of a reel hub is a tape winding surface around which a magnetic tape is wound. In a free state, the tape winding surface forms a substantial taper shape in which an outer diameter is greater at an upper end portion side where a radial direction rigidity is relatively low, than at a lower end portion side where the rigidity is high. In a state in which a magnetic tape is wound, the tape winding surface can form a shape that is substantially symmetrical with respect to a transverse direction of the magnetic tape. As a result, the reel and a recording tape cartridge are obtained in which the outer peripheral surface of the hub forms a proper shape in a state in which a recording tape is wound.

摘要： There are provided a tape reel, a recording tape cartridge, a take-up reel, and a drive device at which, when a recording tape is wound on a hub, fluctuations in an axial direction of the hub can be suppressed and occurrence of tape edge damage can be prevented. At a tape reel having a hub on which a recording tape T is wound and flanges which are provided at both end portions of the hub, a large diameter portion, whose diameter is larger than diameters of both end portion sides of the hub, is formed at the hub. The large diameter portion is offset, from a widthwise direction central portion of the hub, toward the one flange side or the other flange side.

摘要： A reel is provided with a tubular hub, a first flange, a second flange, and positioning portions. A projection portion that projects in a radial direction is formed at an inner periphery face of the hub. The first flange includes a first extension portion which is extended in the axial direction of the hub from a first flange portion and is joined to the projection portion. The second flange includes a second extension portion which is extended in the axial direction of the hub from a second flange portion and is joined to the projection portion. The positioning portions regulate, in the radial direction, positions of distal end portions of the first extension portion and the second extension portion relative to the hub. Gaps are formed between the inner periphery face of the hub and outer periphery faces of the first extension portion and the second extension portion.
