ABSTRACT:
A rotating magnetic head for a magnetic recording reproduction system. The rotating magnetic head detects the position of the rotating head placed on the periphery of a rotating drum, and perform servo control of the position of the movable head. The detection of the position of the rotating head is realized by an optical, non-contact mechanism or by detecting the difference of the track scanned by fixed heads. The former requires more than one movable heads and the latter requires a fixed head.
