ABSTRACT:
In a rotating head magnetic tape transport, magnetic media is transported from a supply spool to a take-up spool. Interlayer slippage, due to air entrapped between tape layers, is reduced by impressing a waveform on the take-up spool motor voltage during high speed search. The impressed waveform has a high acceleration component. As a result of the impressed waveform, a continual jerking action is imparted to the tape to squeeze out entrapped air and leave said tape in a state of tension or tightly wound.
