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： Provided is a reel capable of improving the rigidity of the hub and maintaining the tape characteristics. A single resin layer 36 lying below an aluminum ring 112 in an axial direction of the reel hub 32 and having a wall thickness t2 of 0.8-1.7 mm can suppress the partial rigidity reduction of the reel hub 32. This can suppress the partial characteristic deterioration of a recording tape T wound on the reel hub 32 (partial broadening of the width of the recording tape T, etc.). Besides, crack occurrence can be reduced in the single resin layer 114 of the reel hub 32.

摘要： A recording tape cartridge is disclosed wherein when in non-use, a reel accommodated in a case and having a recording tape wound thereon is prevented from rotating by being meshed with a braking member which is non-rotatble with reference to the case; and when in use, in response to the braking member being pushed up by a release pad or a clutch member, the reel is released from the meshed state and allowed to rotate together with the release pad or the clutch member. With the rotation of the reel, the braking member has its pivot portion disposed in sliding contact with a sliding contact portion formed at a portion corresponding to an axial center of the release pad or the clutch member while being pressed against the sliding contact portion by a biasing force of a compression coil spring. The recording tape cartridge is designed such that a relation μ×L≦0.4 holds between a length L (mm) of the compression coil spring along the axis line of the reel when the reel rotates together with the release pad or the clutch member and a coefficient of dynamic friction μ between the pivot portion of the braking member and the sliding contact portion of the release pad or the clutch member.

摘要： A recording tape cartridge houses a reel including a hub around which recording tape is wound and at least part of which is formed by a resin. The rigidity (modulus of elasticity) y in the radial direction of the hub and the creep deformation ratio x of the recording tape satisfy the conditions of y≧87.3 exp(21.6x) and x>0.1. By setting the rigidity of the reel hub to match the creep deformation ratio of the recording tape so as to satisfy this relationship, creep deformation of the recording tape can be controlled at the smallest cost.
