Abstract: A dynamic tracking reproduction apparatus comprises an actuator for driving a magnetic head in a width direction of recording tracks formed on a recording and reproducing tape; error detector for detecting offsets of the magnetic head from a reference position in the width direction of the recording tracks as positional error signals on basis of signals read from the magnetic head; actuator driver for driving said actuator so that the magnetic head is directed to the reference position on the basis of the detected error signals; and a delay element for correcting time axis of the read signals so that the magnetic head can be located on the reference position on the basis of the detected error signals. Since the time axis fluctuations generated during dynamic tracking operation can be cancelled by the delay element, it is possible to generate reliable reproducing signals free from the time axis fluctuations.
