Abstract

PURPOSE:To exert unidirectional pre-load to the magnetic arm with a simple constitution at all times, by forming the circular arc surface on the magnetic arm and contacting the rotary roller. CONSTITUTION:To the radial direction of the rotary arm group 8 mounting the magnetic head group 7 writing in or reading out information on the magnetic disc group 6, the pre-load receiver 13 made of the curved surface of circular arm in radius R taking the bearing 18 as the center is provided, and it is fitted to the pre-load shaft 14 in rotary free with being restricted for the movement of thrust direction by means of snap ring, and the external circumference is pushed with the pre-load roller 12 formed with the rubber 15. Thus, the bearing 18 is unidirectionally pushed with elastic deformation of rubber 15, the pre-load exerted is added to the rotary arm group 8, and harmful mechanical oscillation can be rejected.
