Disk drive capable of restricting unexpected movement of a head suspension using a latch member to restrict movement of the suspension and elasticity of the suspension to enable a head load tab to move down a ramp inclined surface

Abstract

A guiding passage is formed on a ramp member. The guiding passage defines an inclined surface angled towards plane including the surface of a recording disk at a position toward an inoperative position. A restriction member is allowed to restrict the movement of the load tab on the inclined surface when the load tab moves from the inoperative position toward the recording disk. If an impact acts on a recording disk drive when the recording disk stands still, the restriction member serves to restrict the movement of the load tab on the inclined surface. The elasticity of a head suspension enables the load tab to move down the inclined surface. The downward movement of the load tab causes a reduction in deformation of the head suspension. The head suspension thus receives a smaller load.
