In a magnetic recording device wherein a magnetic head is maintained in elastic contact with a recording medium, an improved magnetic head supporting device integrates a hinge, a swingably supported arm and a magnetic head holding member into a unitary flat spring member. Further, an elongate oil retaining bearing sleeve is provided to guide the magnetic head cartridge in the horizontal or radial direction relative to the recording medium.

In a recording and reproducing device of the type in which a transducing head mounted on a carriage is selectively positionable to read or write data on a recording surface of a flat recording medium, the improvement of a transducing head supporting device comprising: an L-shaped head carriage comprised of a long leg extending parallel to the recording surface of the flat recording medium and a short leg extending perpendicular to the recording surface of the flat recording medium; means movable across the recording surface of the recording medium for mounting the head carriage; a flat spring for carrying the head and for resiliently biasing the head with respect to the long leg of the head carriage, the spring including three integrally formed portions, namely a hinge end portion attached to a distal end of the short leg of the head carriage, an arm portion extending generally parallel to the long leg of the head carriage and a head mounting portion for mounting the transducing head; reinforcement means for encasing at least the side edges of the arm portion and the head mounting portion of the first spring so as to leave exposed the area of the head mounting portion immediately surrounding the head to allow the hinge portion and the head mounting portion to flex while restricting flexure and waving of the arm portion, the reinforcement means further including a protrusion aligned with and adjacent to the head for lightly depressing the head relative to the flat spring and for providing a pivot point support for the head on its side opposite to the recording medium.
