摘要: A control device for controlling tape transport within a system is disclosed. The includes determination unit, which at least first servo channel and second determining lateral position of relative to the head, difference between positions. computing unit computes number unsupported wraps as function difference, wherein corresponds layers around take-up reel having air in-between, spring constant wraps, radius nominal path length. calibration calibrates one dependent on constant.
