Abstract: A gimbals spring for supporting a floating type magnetic head has bent portions formed at both lateral edges of a load beam of the gimbals spring, the bent portions projecting in a direction in which the magnetic head projects from the load beam. A reinforcing plate is secured to the reverse side of the distal end portion of the load beam with respect to the magnetic head in order to make compensation for the strength of said distal end portion which is weakened due to the fact that the bent portions cannot extend as far as the distal end portion of the load beam because of the existence of the magnetic head. Thus, the bent portions do not take part in determination of the overall thickness of the magnetic head including the gimbals spring, which means that it is possible to reduce the thickness of the floating type magnetic head and minimize the size of the magnetic disk drive.
