In tape transport apparatus for use with an 8-mm video tape recorder having an automatic track following system, during reproduction at a variable tape speed, a tracking error signal formed on the basis of a frequency component of a reproduced pilot signal is sampled and held once per one field. The sampled and held output is compared with a reference value, the running state of the tape is positively identified on the basis of the comparison, and tracking control responsive to the identified running state is carried out. The apparatus has the additional capability of skipping pilot signal frequencies in a quasi-locked state to assist in obtaining a locked state.
