ABSTRACT:
A double-sided magnetic head supporting mechanism for reading and writing data on a floppy disk.
One of the magnetic heads is mounted on either a carriage or an arm in a fixed state by a gimbal pair assembly which is movable only vertically and restrained from inclining, and the other magnetic head is mounted on either an arm or a carriage by a biaxial gimbal spring.
The gimbal pair assembly includes a pair of opposing biaxial gimbal springs disposed with a space therebetween and a spacer for fixing the central portions of the gimbal springs. The head is mounted on the central portion of one of the gimbal springs. Since the pair of gimbal springs are integrally fixed at the central portions by a spacer, the gimbal pair assembly can move only vertically, so that parallel vertical movement only is allowed to the head mounted on the gimbal pair assembly with inclination being removed therefrom. Thus, when the double-sided head vertically moves in accordance with the movement of the floppy disk, no offtrack is caused.
