Abstract
A Direct Access Storage Device (DASD), either magnetic or optical, wherein the chamber which encloses the disk, actuator and electrical connections is sealed from the outside conditions by disposing a seal or gasket about a connector which is surface mounted on a flex cable and disposing the connector in a passage through the base of the DASD. The flex cable is disposed adjacent the inner surface of the cover, and a tail portion of the flex cable is folded to an orientation to position the tail so that it may be attached to an actuator or similar mechanism within the DASD. The tail is maintained in its proper orientation once inserted into a slot formed into the base member. The slot side walls constrain the tail without the need to have the tail fixedly attached to the base member at any point and thereby easing assembly, disassembly, rework and/or repair of the DASD. Compressive forces exerted on the flex cable by the cover and cover screws effectively ground the flex cable through a grounding tab engaged with the base. Further, the compressive forces exerted by the cover against the flex cable, gasket, and base member insure an effective seal of the internal chamber of the DASD …
