Abstract
A system for limiting contact between a tape (e.g., magnetic, optical) and opposite reel flanges of a reel assembly as the tape is being wound onto or unwound from the reel assembly to reduce axial and radial tape run out and improve tape drive operations.
Claims16
A system for a tape storage device, comprising:
- a reel including a hub for receiving tape thereon, a first flange member secured adjacent a first side of the hub, and a second flange member secured adjacent a second side of the hub, wherein the second side is opposite the first side;
- and
- a device positioned relative to the hub for reducing an axial distance between first and second lateral edges of the tape to limit contact between the tape and the first and second flange members, wherein the reel is moveable relative to the device.
A tape drive, comprising:
- a housing;
- a reel secured within the housing;
- and
- a device positioned relative to the reel for reducing an axial distance between first and second lateral edges of tape before the tape is received on the reel, wherein the reel is moveable relative to the device.
1 more element
A method for reducing contact between tape and first and second spaced flanges of a reel in a tape drive, comprising the steps of:
- moving the tape along a tape path within the tape drive, wherein an axial distance between first and second lateral edges of the tape is a first axial distance during the moving step;
- and
- receiving the tape between the first and second spaced flanges of the reel, wherein the axial distance between first and second lateral edges of the tape is a second axial distance during at least a portion of the receiving step, and wherein the second axial distance is not greater than about 70% of the first axial distance.
