Abstract
PURPOSE: To operate a head disk assembly (HDA) self-damping brake by a link mechanism for transmitting the tension of an HDA driving belt to an HDA self- damping brake release truck, and to stop it quickly when a fault has occurred.
CONSTITUTION: A pulley 10 attached to an HDA13 fixed to a base plate 1 and a pulley 9 attached to a drive motor 2 mounted to a motor plate 4 are well- balanced by a drive belt 8 and a spring 5. In case when such a fault as cut of detachment of the drive belt 8 has occurred, the spring 5 contracts, a shaft 7 is drawn toward the side of a shaft 6, the motor plate 4 is moved to a position of 4' centering around a shaft 34, a lever 33 is moved to a position of 33' centering around a shaft 32, and a truck 29 connected by a shaft 36 is moved to a position of 29'. A bearing 27 of the truck 29 is separated from inclined surface parts 22b, 23b of levers 23, 23, a friction plate 12 is pinched by brake pads 24, 25, and an inertia rotation of a spindle shaft 11 is stopped.
