ABSTRACT:
A thermoelectrically adjustable magnetic head for reading and writing information comprising a read/write core, and position detection cores on both sides thereof generating compensatory output in proportion to the relative positional drift of the magnetic head with position detection and correction device from the center lines of a magnetic disk data tracks by feeding back signals to the magnetic head to rectify said magnetic head's position to the center of said disk data tracks, and in the course of such compensatory operation also eliminates noise generated at the time of recording from the gaps between said tracks.
