Abstract

PURPOSE:To execute a stable positioning control by forming a position signal by rectifying and adding a positioning use burst signal reproduced by two position sense use head groups, in the opposite direction. CONSTITUTION:For instance, two pieces of position sense use heads 3a, 3b having TW' in which core width is narrower than track width TW placed at an equal interval TP are placed by holding a relation of TP+ or -(TW-TW')/2, with respect to a recording/reproducing head 2, and a discriminating signal and a burst signal for positioning, whose frequency is lower than a data frequency are recorded to the track in a shape of a sector. In this state, a position signal is formed by rectifying and adding the positioning burst signal reproduced by one position sense use head 3a and the positioning burst signal reproduced by the other position sense use head 3b, in the opposite direction. In such a way, the position signal is formed based on only a reproduced output from an area 22 in which the burst signal is recorded, and an exact position signal which is not influenced by a resolution is formed.
