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: A system includes a first preamplifier, a second preamplifier and a flex circuit. The first preamplifier is configured to be connected to a first plurality of recording heads. The second preamplifier is configured to be connected to a second plurality of recording heads. At least one of the first plurality of recording heads and at least one of the second plurality of recording heads are configured to concurrently perform read and or write operations. The flex circuit is a single flex circuit configured to connect the first and second preamplifiers to the plurality of recording heads.

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: Systems and methods for a flexible dynamic loop having reduced impedance are described. The flexible dynamic loop may supply current from a preamplifier to another device, such as a hard disk drive. In one embodiment, a flexible dynamic loop comprises a flexible structure having a set of wire traces. The flexible dynamic loop may also comprise a set of impedance control structures on the flexible structure and perpendicular to a bend radius of the flexible structure, wherein the set of impedance control structures change an impedance level experienced by at least some of the set of wire traces. Some of the impedance control structures may be staggered. The flexible dynamic loop may also include a cover layer formed over the set of impedance control structures, which may be patterned with perforations. The flexible dynamic loop may also include one or more flexible rails connecting some of the impedance control structures.
