摘要： A data storage tape cartridge including a housing, first and second tape reels, a storage tape, first and second corner guides and an idler wrap guide. The housing defines a head access window. The tape reels are rotatably disposed within the housing, with the storage tape extending between the tape reels. The first and second comer guides are disposed within the housing at opposite sides of the head access window. Finally, the idler wrap guide is disposed within the housing and defines a tape path extending from the first tape reel to the idler wrap guide, and from the idler wrap guide to the first corner guide. The idler wrap guide is configured to frictionally dampen lateral movement of the storage tape upon rotation of the tape reels to greatly reduce servo off track events.

摘要： A tape reel assembly for a data storage tape cartridge is described. The tape reel assembly has a hub. The hub includes a cylindrical core, an annular arm, and a web. The cylindrical core defines a drive side and a top side. The annular arm is co-axially disposed exterior to and separated from the cylindrical core. Additionally, the annular arm defines a tape winding surface bisected by a center line into a top half opposite the drive side and a bottom half adjacent the drive side. The web extends from the top side of the core, and a web center connects to the annular arm at a point in the top half.

摘要： A leader block assembly including a leader block, a tape clamp, and an elastomeric member. The leader block forms a channel defined by opposing sidewalls extending from a base, each sidewall forming a lip having an under surface. The tape clamp is nested within the channel and includes a bottom surface, opposing sides, and at least one cantilevered leg positioned at each of the opposing sides, respectively. Each leg extends upwardly relative to the bottom surface. The elastomeric member is disposed between the leader block and the tape clamp, and biases the tape clamp to a locked position in which the legs engage the under surface of the respect lips providing positive engagement between the tape clamp and the leader block.

摘要： A data cartridge of the type in which magnetic recording tape is reversibly driven from one spool to another by an endless elastic drive belt contacting the periphery of the tape spools, a drive roller, and two located rollers at opposite corners of the cartridge. Tape tension and drive force are controlled by predetermined drag resulting from magnetic brakes built into the corner rollers.

摘要： A prism is provided for deflecting light through the tape information holes in the tape of a data cartridge. The prism includes a substantially hollow main prism body. The inside surface of the angled prism surface is formed in steps, so that light passing into the angled portion passes in the normal direction through a step, is reflected off of the angled surface, and then passes in the normal direction through the adjacent side of the step, or the adjacent side of the next step. In this fashion, minimal plastic material is required for the prism, while light reflection is restricted to only a single surface. An alternative embodiment provides steps on the internal surface of a mirror, instead of a prism.

摘要： In a belt driven tape cartridge, tape tension is controlled by a yoke which articulates in a region between the tape packs. The yoke includes at least two rollers, one mounted adjacent each tape pack, for rotation on shafts constrained in the yoke. The cartridge belt is stretched around the drive roller and the yoked rollers to pull the yoke mechanism into firm engagement with the tape packs.

摘要： Stretched surface recording disk (SD) 10 comprises an annular support 12 having raised annular ridges 42 and 28 at its inside and outside diameters 22 and 30 with a base portion 24 in between the two ridges, and an annular recording medium film 14 held in radial tension and stretched across the base portion by adhering the film to attachment surfaces 48 and 36 near the inside and outside diameters respectively. The SD is annealed twice during manufacture to relieve stress in the stretched film 14. This annealing results in SD essentially free from track anisotropy and stress distribution anisotropy in the plane of the disk. As a result, data tracks are more stable than in previous SD, track density can be greater, and the SD is generally more reliable.

摘要： A plunger assembly for pressing together two smooth layers of material against a firm planar supporting surface without entrapping air between the layers. The assembly includes a soft resilient pad having adjacent surfaces disposed at an obtuse angle and meeting at a ridge. The pad is pressed against the material to first engage the ridge and then the adjacent surfaces progressively outwardly from the ridge to sweep air from between the layers of the material.
