PURPOSE:To eliminate a read error by applying the internal force to the gaps existing at the hook part, the coupling part and the rubbing part among component parts to eliminate those gaps. CONSTITUTION:A part A serving as a bearing part 23 of a feed motor 10 contains a spring 26 which has a contact with a roll 23b to give force to the roll 23 obliquely in the upper left direction. While a part of a bearing B has an angular bearing 27, and the component force of the spring 26 pushes the bearing 27. A roll 28 is energized toward a head 5 by a spring 29. A working point Pg has a vector of the force in the direction where the shaft of a gear system 13 increases the distance to the shaft of a gear system 14. While a working point Pe also has a vector of the force in the direction where the distance is increased between the system 13 and a rack 6. Then three guide rings 25 are provided to control the head surface, and a spring 30 and a roll 31 are used to energize the head 5 toward a disk 4. At a bearing rubbing part between the rotary shaft of a disk drive motor 2 and a turntable 3, rolls 20 and 21 energized by a spring 22 are pressed to a taper surface 19. In such constitution, the relative motions are never produced among component parts despite the application of impact or vibrations. |
