Patent ID: 7468868

Claim:
A rotary disk storage device comprising: a housing; a rotary disk recording medium, said rotary disk recording medium having a data area and being rotatable about a spindle shaft supported by a bottom of said housing; a slider to which a head is attached to read data from said rotary disk recording medium; a suspension assembly to which said slider is attached; an actuator assembly to which said suspension assembly is attached, said actuator assembly including a first arm and a second arm and being adapted to turn about a pivot shaft so that said head moves between said data area and a retraction area, said pivot shaft being supported by the bottom of said housing; a stopper including an elastic member, said elastic member being cantilevered by a support rod and with a magnetic material embedded therein for attracting said actuator assembly, the elastic member configured to engage said first arm and said second arm; and a swivel stop abutted against an outer surface of said elastic member, said swivel stop being disposed in such a position as prevents rotation of the elastic member centered on a support point of said stopper; wherein, when either said first arm or said second arm of said actuator assembly comes into abutment against said elastic member, the elastic member undergoes a moment of force so as to restrict an excessive movement of said actuator assembly to an inner or an outer side, and cushions said abutment.
