Abstract: An optical tracking system is presented which aligns a recording head with a magnetic tape. The system relies on an optically detectable servo track on the back of the tape. The servo track is formed by repeatedly engraving, at spaced intervals, three co-linear marks perpendicular to the length of the tape. Laser light reflects off the marks, and passes through a ball lens that directs the reflected light on to separate light detectors, one for each mark. By recording characteristics of the reflected light, the detectors transmit information to the system that permits the recording head to be properly aligned with the tape.

Abstract: An optical tracking system is presented which aligns a recording head with a magnetic tape. The system relies on an optically detectable servo track on the back of the tape. The servo track is formed by repeatedly engraving, at spaced intervals, three colinear marks perpendicular to the length of the tape. Laser light reflects off the marks, and passes through a ball lens that directs the reflected light on to separate light detectors, one for each mark. By recording characteristics of the reflected light, the detectors transmit information to the system that permits the recording head to be properly aligned with the tape.

Abstract: 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.
