ABSTRACT:
A magnetic head having an upper head and a lower head disposed opposite to each other and capable of simultaneously reading information from or writing information in both sides of a magnetic disc inserted therein. The upper head is fixed to a wingable arm at correct vertical position and inclination, while the lower head is mounted through a gimbals spring on a carriage which is slidable along a guide rod or guide rods in the radial direction of the magnetic disc. Since the upper head is positioned correctly and the surface thereof facing the lower head serves as a datum surface, the inclination of the lower head need not be adjusted in assembling the magnetic head, and thereby the process for assembling the magnetic head is remarkably simplified.
