ABSTRACT:
In a data writing and/or reading device in which data is written and/or read out from a rotating recording medium, a head carriage upon which one or more heads are mounted is guided by first and second guide rods to move in a predetermined direction with respect to the recording medium. A member for biasing the head carriage in the direction opposite the direction of a rotating force produced by the friction between the head or heads and the recording medium is provided. This force in the direction of rotation of the recording medium is counteracted so that deviation of the head in the direction of rotation of the recording medium is eliminated.
