A magnetic head unit comprising a magnetic head supporting member provided with a magnetic head receiving hole formed in an extremity thereof, and a reading/writing magnetic head placed within the magnetic head receiving hole at a correct position with respect to reference surfaces formed in the underside of the magnetic head supporting member and adhesively fixed to the inner surface of the magnetic head receiving hole. The magnetic head unit is assembled by placing the magnetic head supporting member on a jig having a magnetic head supporting groove and protrusions for supporting the magnetic head supporting member thereon so that the reference surfaces of the magnetic head supporting member are located in parallel to and at a predetermined height from the bottom surface of the magnetic head supporting groove, inserting the magnetic head into the magnetic head receiving hole and placing the same on the bottom surface of the magnetic head supporting groove, temporarily fixing the magnetic head to the inner surface of the magnetic head receiving hole with a quick hardening adhesive, and firmly fixing the magnetic head to the magnetic head supporting member with an adhesive.

Magnetic head unit and method of manufacturing the same

A magnetic head assembly including a carriage which carries thereon a first magnetic head for information writing and reading to and from one side of a disc-like magnetic recording medium, and a hold case which carries thereon a second magnetic head for information writing and reading to and from the other side of the magnetic recording medium, the second magnetic head being disposed in a position opposed to the first magnetic head, the hold case being connected to the carriage through hinge means rotatably to a certain degree relative to the carriage, and the magnetic head assembly being reciprocated in a radial direction of the magnetic recording medium. The first magnetic head is mounted on the carriage through a gimbal spring which is formed rotatably to a certain degree with respect to biaxial hinge portions, and the second magnetic head is mounted on the hold case through a spring plate which is formed rotatably to a certain degree with respect to a uniaxial hinge portion. The hold case is urged toward the carriage on the side of the hinge means rotatably to a certain degree relative to the carriage.
