The present disclosure generally relates to tape assembly implementations for magnetic recording devices, such as tape embedded drives (TEDs). In one or more embodiments, one or more of a first reel and/or a second reel is laterally movable relative to a side wall of a casing of the tape assembly. In one or more embodiments, a drive assembly laterally moves the first reel and the second reel substantially simultaneously such that a spindle distance between a first spindle and a second spindle is substantially constant.

The magnetic tape cartridge includes a magnetic tape, and a cartridge reel, in which, in the magnetic tape, a minimum winding deviation occurrence load measured after the magnetic tape is rewound around the cartridge reel by applying a tension of 0.20 N in a longitudinal direction of the magnetic tape is 200 N or less.

A tape is prevented from moving in a width direction and the tape is prevented from being damaged in a state in which the tape is wound around a tape reel. There is provided a tape reel including: a cylindrical portion around which a tape is wound; a first flange annularly projecting toward an outer side in a radial direction of the cylindrical portion from the cylindrical portion; and a second flange separated from the first flange in an axial direction of the cylindrical portion and annularly projecting toward the outer side in the radial direction from the cylindrical portion, in which a distance between the first flange and the second flange becomes narrower while extending toward the outer side in the radial direction, and a bending elastic modulus of the first flange is smaller than a bending elastic modulus of the second flange.

The present disclosure generally relate to tape assembly implementations for magnetic recording devices, such as tape embedded drives (TEDs). In one or more embodiments, a first reel and a second reel are mounted at stationary positions. One or more of the first reel and/or the second reel includes a hub mounted to a spindle, and a single flange extending relative to the hub. In one or more embodiments, one or more of a first reel and/or a second reel each includes a flangeless hub mounted to a spindle.

A hub includes a hub body around which a magnetic tape is wound, and a noncontact storage medium provided in the hub body, in which the noncontact storage medium stores hub specification information for specifying the hub body, and the hub specification information is associated with hub change characteristic information indicating a change characteristic of the hub body.

A tape cartridge according to an embodiment of the present technology includes: a first tape reel; a magnetic tape; a leader pin; and a second tape reel. The magnetic tape is wound around the first tape reel. The leader pin is attached to an end portion of the magnetic tape and includes a shaft portion parallel to a tape width direction. The second tape reel includes a cylindrical reel hub, a first flange, and a second flange. The reel hub has an inner peripheral surface and an outer peripheral surface, a housing unit capable of housing the leader pin being provided on the inner peripheral surface or the outer peripheral surface. The first flange is provided to one end portion of the reel hub. The second flange is provided to the other end portion of the reel hub and includes a slit portion through which the magnetic tape is capable of passing.
