Abstract: A secure cartridge-based storage system includes a set of read/write control electronics on a control board adapted to removably couple with each of a plurality of storage cartridges. For each individual storage cartridge, the read/write electronics are adapted to retrieve a unique device identifier from the storage cartridge; retrieve an encryption key stored on the control board in association with the unique device identifier; and utilize the encryption key to encrypt or decrypt data that is in transit to or from a target storage location on the storage media.

Abstract: In one aspect, a data storage device includes a disc, an arm, a head, a linear driver, and an elevator. The disc has a read/write surface defining an x-y plane. The arm has a head end that is movable relative to the disc. The head is configured to interact with the read/write surface. The linear driver is configured to move the arm along a substantially straight line in the x-y plane. The elevator is configured to move the arm in a z direction. In another aspect, rather than a linear driver, the data storage device includes a rotary actuator and a pivot actuator. The arm includes a first portion and a load beam. The rotary actuator is configured to move the first portion about a first pivot axis; the pivot actuator is configured to move the load beam about a second pivot axis relative to the first portion.

Abstract: 3D optical data storage refers to forms of optical data storage in which information can be recorded and/or read with 3D resolution. 3D optical media are generally limited in areal density by the diffraction limit of laser light used to read and/or write data to and/or from the optical media. It is thus advantageous to find ways to store data on 3D optical media with a spot size below the diffraction limit of an associated laser reader to further increase areal density of the optical media. A hybrid approach that utilizes plasmon technology to access a surface layer of the 3D optical media with an extremely small spot size and photon technology to access interior layers of the 3D optical media with a larger spot size may substantially increase overall data density of the 3D optical media.

Abstract: A data storage library includes a number of storage cartridges arranged in a rack accessed by a actuated media player. The actuated media player is adapted to move the along a plane relative to a fixed subset of the storage cartridges in the rack to and to selectively couple to each storage cartridge of the fixed subset to facilitate selective read/write access.

Abstract: A hard disc drive includes a slider including a first reader and a second reader. The hard disc drive also includes a magnetic recording medium and a controller. The controller is configured to determine a distance between the slider and the magnetic recording medium based at least in part on amplitudes of read signals from both the first reader and the second reader.

Abstract: A data storage device includes a ramp configured to support at least one head in the data storage device, and a movement mechanism coupled to the ramp and configured to move the ramp from a first position to a second position by at least one of expansion or contraction of at least a portion of the movement mechanism. The data storage device further includes a ramp motion control module operably coupled to the movement mechanism. The ramp motion control module is configured to provide the movement mechanism with a first control signal that causes the movement mechanism to move the ramp from the first position to the second position. The data storage device additionally includes a latch configured to hold the ramp.
