Tape reel with flange sections for uniform tape stacking

摘要

A tape drive reel for providing controlled, uniform stacking of tape during read/write operations to reduce lateral tape motion. The reel comprises a hub and two flanges that are located on opposite sides of the hub. Each flange includes a deflectable radial section which pivots about the hub as tape is wound onto the reel. As each loop of tape is wound on the hub and the amount of tape stacked thereon increases, the radial sections of the flanges are deflected towards each other and against the opposite edges of the tape stack, ensuring that the tape stacks uniformly.
