  • Patent number: 3939493
    Abstract: Various pneumatic means are shown for lifting tape locally away from a rotating head as the rotating head moves. Only the tape in the vicinity of the head is lifted. The lifting is done with minimal pneumatic force, and done only locally about the head so that recovery time for read/write operations after a lifting operation is short, Air to lift the tape can be blown from passages around the head, from passages through the head, or from passages in front of the head. Local lifting about the head is enhanced by insuring that the pneumatic air flow to lift the tape does not easily dissipate in air space between the mandrel and the head rotor.
