Method and apparatus for providing coarse and fine radial positioning of a multiple head assembly relative to the concentric tracks of a rotatable magnetic disk. In addition to a plurality of data heads, the head assembly also includes a pair of position sensing heads having skewed core gaps disposed at an angle with respect to each other. These position sensing heads are used for prerecording concentric position control tracks on the disk as well as for subsequent sensing of position control information during both coarse and fine positioning operations. The position control information prerecorded in the position control tracks is specially chosen so as to provide a pair of pulse trains during position sensing having characteristics such that highly accurate and reliable control of head position can be achieved based upon a detection of the coincidence relationship between predetermined pulses of the respective pulse trains.
