An encryption communications appliance provides data encryption management for a data storage library. The appliance is coupled to an encryption-capable storage device, a data storage library controller within the data storage library and with an encryption key manager (EKM). The encryption command communications appliance intercepts encryption key requests from the data storage device and transparently forwards the requests to the EKM. The appliance also forwards transparently communications between the library controller and the data storage device.

An apparatus, system, and method are disclosed for hard disk drive redundancy. A demarcation module demarks a parity data block in each set of a specified number of data blocks on a hard disk drive. An association module associates a PBA of each un-demarked data block with a LBA. A write module writes the data to the un-demarked data blocks. A parity module calculates parity data for the data written to the un-demarked data blocks and the write module writes the parity data to the parity data block.

A magnetic storage media has a servo track segment and a timing based servo band recorded on the servo track segment. The timing based servo band includes a modulated timing based servo pattern string representative of magnetic encoded servo position information for facilitating a determination of a servo position error signal. Exemplary forms of the modulation of the timing based servo pattern string includes a pattern interspacing modulation, a magnetic intensity modulation, and a pulse position modulation.

A dual-path optical recording medium and an apparatus for accessing such are disclosed. The dual-path optical recording medium includes a substrate, an intermediate recording layer, a holographic recording layer and a dichronic mirror layer. The intermediate recording layer is a rewritable data storage layer with a relatively low storage capacity. The holographic recording layer is a write-once data storage layer with a relatively high storage capacity. The dichronic mirror layer is located between the holographic recording layer and the intermediate recording layer. The apparatus for accessing the dual-path optical recording medium includes a first light module capable of generating a first laser light, and a second light module capable of generating a second laser light.

A holographic storage media incorporates a holographic recording layer for storing holographic data and a DVD reflective layer for storing control information. The DVD reflective layer is positioned within the holographic storage media relative to the holographic recording layer to enable individual optical access to the holographic recording layer via a data laser light for processing the holographic data and individual optical access to the DVD reflective layer via an information laser light for processing the control information. The holographic recording layer and the DVD reflective layer may be physically separated by one or more intermediate reflective layers. The data laser light and the information laser light may differ in one or more optical characteristics. The holographic recording layer and the DVD reflective layer may be optically accessed by the respective laser lights through different light transparent faces of the holographic storage media.

A velocity calculator performs high-order calculations of servo frame velocities of a storage media, particularly tape and disk. The velocity calculator employs a servo frame indexing module for generating a first-order preceding servo frame velocity signal indicative of a first-order calculation of a preceding servo frame velocity including a first-order preceding servo frame error term based on first-order current servo frame velocity signal indicative of a first-order calculation of a current servo frame velocity including a first-order current servo frame error term. The velocity calculator further employs a velocity estimating module for generating a higher-order current servo frame velocity signal indicative of a second or higher order velocity calculation of the current servo frame velocity including a higher-order current servo frame error term based on the first-order preceding servo frame velocity signal and the first-order current servo frame velocity signal.
