Method of mounting a magnetic head

A method of mounting an upper magnetic head, having a sliding contact surface on a lower side and a mounting surface on an upper side thereof, to one end of a pivotable case which extends longitudinally over a carriage supporting a lower magnetic head, said upper magnetic head being mounted precisely to said one end of said case such that when said case is pivoted downwardly toward said carriage, said upper magnetic head faces opposite said lower magnetic head on opposite sides of a magnetic disk interposed in a plane therebetween, said case being provided with a mounting surface on said one end for mounting the magnetic head, comprising:

• employing a jig having a grooved placing unit with a bottom surface formed downwardly in the jig and a pair of supports projecting upwardly from the jig by a predetermined height above, and spaced apart longitudinally and in parallel with, the bottom surface of the groove placing unit;
• placing the sliding contact surface of the head on the bottom surface of the placing unit of the jig to position the head therein;
• placing the case longitudinally on the pair of supports so that its mounting surface on said one end thereof is located opposite the mounting surface of the upper side of said head and spaced from the contact surface placed on the bottom surface of said placing unit by a predetermined spacing determined by the predetermined height of the supports;
• and
• filling a bonding agent in a resulting gap between the mounting surfaces of the head and the case created by said predetermined spacing and allowing the head and case to bond together.
