ABSTRACT:
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.
