摘要： A rebounding phenomenon of an actuator assembly is to be prevented and device assembling work and maintenance work are to be carried out separately from stopper removing work. In one embodiment, a magnetic disk device includes a stopper 50 for restricting a turning range of an actuator assembly 8 having a coil support 22 in a magnetic disk device. In the stopper 50, rubber 51 is cantilevered by a support rod 261 so as to undergo a moment of force and fulfill a shock absorbing function in order to restrict an excessive movement of the actuator assembly 8 to an inner or an outer side when the rubber 51 is abutted against a first arm 22a or a second arm 22b of a bifurcated shape of the coil support 22, the support rod 261 is disposed outside a turning track of turning ends of the first and second arms 22a, 22b of the coil support 22, and a permanent magnet 52 is embedded in the rubber 51 to attract the first and second arms 22a, 22b.

摘要： The invention prevents the deterioration of the read/write performance of a hard disk drive due to the interference between an inertial latching mechanism and an actuator when a head slider holding a magnetic head is located at a read/write position. A latching arm 22 provided with a projection 23 and included in an inertial latching mechanism 20, and a part 161 of a coil holding arm 16a included in an actuator are formed in shapes such that the latching arm 22 provided with the projection 23 does not interfere with the coil holding arm 16a having the part 161 when a head slider mounted on the actuator is located at a read/write position on a magnetic disk.

摘要： A damping material to increase a damping ratio is disclosed. In one embodiment, an actuator arm assembly of a hard-disk drive (HDD) comprises an actuator arm. A viscoelastic layer is coupled with the actuator arm. A constraining layer is coupled with the viscoelastic layer on a side of the viscoelastic layer opposite the actuator arm. The coupling of the actuator arm, the viscoelastic layer, and the constraining layer occurs over an area which is a fraction of the area between the constraining layer and the actuator arm.

摘要： Turbulence of an airflow returning to a magnetic disk along the base sidewall of a HDD is reduced to thereby reduce flutter of an actuator or a magnetic disk caused by the airflow, thus improving read/write performance. An HDD according to an embodiment of the present invention comprises a base, a top cover fixed to the base, a motor for rotating a magnetic disk, an actuator for moving a head which gets access to the magnetic disk, a ramp slope portion on which an extreme end is ridden up, a ramp support portion for supporting the ramp slope portion, and a stage for holding the ramp support portion. A flow passage is formed which runs toward the magnetic disk through an area near the ramp support portion on the side of the top cover. An inclined portion running toward the bottom of the base is formed on the end of the flow passage on the side of the magnetic disk.
