Technologies are described herein for implementing a space-efficient internal energy storage apparatus in a data storage device or other electronic device have a metallic or otherwise electrically-conductive housing or case structure. A first carbon layer is applied to an inner surface of the metallic housing, and a dielectric spacer is applied upon the first carbon layer. Next, a conductive layer having a second carbon layer is applied over the dielectric spacer, and the metallic housing and the conductive layer is electrically connected to a circuitry of the electronic device.

Energy storage apparatus in device with conductive case structure

Apparatus and method for managing data in a multi-device data storage system. In some embodiments, a plurality of data storage devices are provided, each data storage device having a local driver circuit adapted to transfer data with a local memory module. A main driver circuit external to the plurality of data storage devices is configured to stream frequency modulated write data via parallel data transfer paths to the respective local driver circuits for concurrent transfer of the frequency modulated write data to the respective local memory modules.

Multi-device storage with consolidated channel and control circuitry

A mass data storage system includes a number of communicatively coupled storage drives powered and controlled by shared control electronics. The shared control electronics are configured to transmit analog read/write signals through an interconnect to each of the multiple individually selectable storage drives. The interconnect bi-directionally couples the control electronics to each of the multiple selectable storage drives.

Interconnect for shared control electronics

A charge leveler coupled between an external power supply and a data storage device includes a current limiter to receive an input current from the external power supply and to provide a limited input current at no more than a pre-determined level. A charge reservoir couplable in parallel with an output of the current limiter supplements the limited input current when the pre-determined level is exceeded. The charge reservoir is replenished with surplus limited current when the data storage device draws less than the pre-determined level. A boost assist regulator monitors a requested current from the data storage device, and initiates operation of the charge reservoir to supplement the limited input current when the requested current exceeds the limited input current.

Adaptive charge leveling in a data storage device

An apparatus includes a communication interface, a controller, and a power section. The communication interface is configured to receive power from an external host to the apparatus. The controller is configured to limit a current drawn by the communication interface to a predetermined value when the apparatus is powered through the external host. The power section is configured to generate a first voltage from a portion of the limited current drawn by the communication interface. The first voltage powers a data storage circuitry. The power section is further configured to store electrical charges received from another portion of the limited current drawn by the communication interface. The power section is further configured to generate a second voltage from the stored electrical charges in response to a signal from the controller. The second voltage supplements the first voltage during high power events by the data storage circuitry.

Portable storage device with charge reservoir for higher current operations

Technologies are described herein for implementing a space-efficient internal energy storage apparatus in a data storage device or other electronic device have a metallic or otherwise electrically-conductive housing or case structure. The energy storage apparatus comprises an interior surface of the metallic housing, a conductive layer disposed parallel to the interior surface of the metallic housing, and a separator disposed between the interior surface and the conductive layer. The metallic housing is configured to act as a first electrode of the energy storage apparatus and the conductive layer is configured to act as an opposing electrode to the first electrode.

A rigid multi-layer printed circuit board (PCB) has an embedded elongated conductor between opposing first and second reference planes. The first and second reference planes are formed of conductive material and are electrically isolated from the conductor by intervening insulative material. Each of the first and second reference planes have a plurality of spaced apart windows extending therethrough, the windows aligned with the elongated conductor.

Windowed reference planes for embedded conductors

A system that includes a first data storage element actuated by a first electric motor. The system also includes a second data storage element actuated by a second electric motor. An electrical connector assembly transfers electrical energy from a back electromotive force generated in the first electric motor, by movement of the first data storage element, to the second electric motor to thereby energize the second electric motor.
