ABSTRACT:
A support apparatus for the magnetic heads of a two-sided floppy disk drive has a first magnetic head which is elastically supported on the front portion of a carriage so as to be able to move in the normal direction of a floppy disk, and a second magnetic head which is supported by the front portion of a rotating arm. The rotation of the arm towards the floppy disk is restrained by an arm support. In a first embodiment, the first magnetic head is supported by a first gimbal spring which is secured to the carriage, and the second magnetic head is secured to a steel plate which is secured to the arm. In a second embodiment, the second magnetic head is supported by a second gimbal spring which is secured to the arm which has a greater stiffness than the first gimbal spring.
