Various aspects of the present disclosure are directed toward a disc driver apparatus including a base, a disc drive actuator assembly, and a vapor-trapping pathway. The base, in certain embodiments, has an upwardly-facing portion with a first step and an adjacent second step that is vertically lower than the first step. The disc drive actuator assembly in some embodiments includes a pivot shaft, an E-block, and a plurality of bearings. The pivot shaft is fixed relative to the base, and the E-block has a portion facing the upwardly-facing portion of the base. The plurality of bearings are designed to facilitate rotation of the E-block around the pivot shaft. The vapor-trapping pathway includes the first step and a trap region that is partly defined by the second step, the vapor-trapping pathway being designed to pass vapor flow outwardly, relative to the pivot shaft, from a level below the bearings to the trap region.

Disc drive apparatus with vapor-trapping pathway

The present invention includes a method and apparatus for attenuating flexible circuit resonance. The apparatus includes a flexible circuit assembly. The flexible circuit assembly has a flexible circuit having a flexible cable with first and second sides. The flexible circuit assembly also includes a circuit support. The circuit support includes a base having top and bottom surfaces. The bottom surface is attached to the first side of the flexible cable. The circuit support also includes a support wall extending substantially perpendicularly relative to the top surface of the base. The support wall has a first face, which is substantially oriented towards the top surface of the base. The first side of the flexible cable is attached to the first face and also faces a second face of the support wall to thereby reverse a direction in which the flexible cable faces.
