Abstract: A data storage device includes a first actuator and a second actuator rotatable around a common axis. The data storage device further includes a first electrical connector configured to communicate electrical signals to and from the first actuator via a first flexible circuit. The data storage device further includes a second electrical connector separate from but in a stacked arrangement with the first electrical connector. The second electrical connector is configured to communicate electrical signals to and from the second actuator via a second flexible circuit.

Abstract: According to some embodiments, a storage device includes a first actuator and a second actuator rotatable around a common axis. The storage device further includes a first electrical connector configured to communicate electrical signals to and from the first actuator, and a second electrical connector configured to communicate electrical signals to and from the second actuator and to communicate electrical signals to and from the first electrical connector. The storage device includes a hermetically-sealed body, the hermetically-sealed body including a base deck and a top cover, wherein the second electrical connector is configured to send and receive electrical signals to and from the first actuator and the second actuator through a single aperture in the hermetically-sealed body.

Abstract: An apparatus includes at least one actuator shaft. First and second head stack assemblies are coaxially located on the actuator shaft(s). The first and second head stack assemblies each include: at least one bearing having an inner race coupled to an outer surface of the actuator shaft(s); an E-block surrounding an outer race of the at least one bearing; an annular gap is between the E-block and the outer race of the at least one bearing; a ring of bonding material filling the annular gap; and an access gap providing a fluid path to the annular gap from at least one of a top and a bottom of the E-block.
