Abstract
A tape tracking device for a tape recorder comprises first and second position detection heads disposed such that one of the first and second position detection heads is upwardly displaced by its one upper half from a track on which a signal is recorded and reproduced by a record/reproduce head and the other is downwardly displaced by its one lower half from the track, a DC reversible motor rotated according to a difference between the reproduced signals of said first and second position detection heads, and a post tiltable by an eccentric cam attached to a shaft of the motor and adapted to impart a pressure in the up and down directions to correct a deviation of the tape in the direction of the width of the tape.
