Abstract: Apparatus are disclosed for reproducing information from an information carrying tape wherein the tape is advanced by the imposition of a first force longitudinally of the tape, and wherein a second force extending into the plane of the tape at an angle to the first force is imposed. A flutter component is detected in information reproduced from the tape, and the second force is varied in response to the detected flutter component in the sense of a flutter reduction. Advantageously, the mentioned first force may be varied in response to a low-frequency flutter component, while the second force may be varied in respone to a high-frequency flutter component. Piezoelectric tape drive capstan, tape guiding and reproduce head actuating or mounting systems are also disclosed.
