Abstract

Disclosed herein is a dual-actuator magnetic storage device comprising: a housing; a magnetic disk in the housing; an interface connector positioned proximate to the housing formed by a first short side and a first long side a first corner of the housing; a first voice coil motor, a second corner of the first voice coil motor near the first short side and a second long side; a first carriage arm, the first a carriage arm positioned adjacent the first short side to move the first carriage arm relative to the disk; a second voice coil motor positioned along the first long side to proximate to the second short side; a second carriage arm located proximate to the second short side and coupled to the second voice coil motor to move the second carriage arm. The interface connector is recessed into the base of the housing proximate the first long side along the first short side to provide electrical communication through the housing.

Description

technical field [0001] The present disclosure relates generally to magnetic storage devices, and more particularly, to increasing the storage capacity of magnetic storage devices. Background technique [0002] Magnetic storage devices, such as hard disk drives ("HDDs"), are widely used to store digital data or electronic information in enterprise data processing systems, computer workstations, portable computing devices, digital audio players, digital video players, and the like. Typically, HDDs contain read and write heads that help facilitate data storage on the disk. Storage capacity is limited by the available area and areal density capabilities of HDD storage elements. Contents of the invention [0003] There is a need for a magnetic storage device and method of manufacturing the same that meets small form factor standards and provides improved storage capacity within size constraints, as data storage applications such as data center storage systems have been widely ...
