Abstract
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 stopperfor restricting a turning range of an actuator assemblyhaving a coil supportin a magnetic disk device. In the stopper, rubberis cantilevered by a support rodso as to undergo a moment of force and fulfill a shock absorbing function in order to restrict an excessive movement of the actuator assemblyto an inner or an outer side when the rubberis abutted against a first armor a second armof a bifurcated shape of the coil support, the support rodis disposed outside a turning track of turning ends of the first and second armsof the coil support, and a permanent magnetis embedded in the rubberto attract the first and second arms
