ACCURATE RADIUS AND VELOCITY MEASUREMENT OF TAPE TRANSPORTS |
| 摘要 |
A method according to one embodiment includes computing a radius value of a tape on an outgoing reel during unwinding of the tape from the outgoing reel, adjusting the computed radius with an offset calculated from a direct measurement of velocity from the tape position, and outputting the adjusted computed radius. A method according to another embodiment includes computing a radius value of a tape on an incoming reel during winding while the tape is being wound onto the incoming reel, adjusting the computed radius with an offset calculated from a direct measurement of velocity from the tape position, and outputting the adjusted computed radius. |
