A method and a structure for mounting to a head carriage a magnetic head applicable to a magnetic recorder or reproducer in an electronic camera system wherein an object is electronically photographed and recorded into a rotating magnetic disc and an image is reproduced by a television system or a printer. In the method and structure, a pin is inserted through a through-bore in a head mount plate and is then brought into abutment with the head carriage. Adhesives are applied to clearances between the pin and the through-bore of the head mount plate as well as between the pin and the abutment surface of the head carriage to fill them up. In the method and structure, since the head mount plate is adhesively attached to the head carriage via the pin, the resultant adhesive layers are reduced in thickness, thereby preventing the magnetic head from shifting out of position when the adhesives are hardened.
