Abstract: A data storage system that includes a data migration assembly implemented using tape drive technology. The migration assembly includes tape drive modules or cards stacked within a tape drive chassis, which is adapted for insertion into a tape drive slot of a library or rack enclosure. The data storage system includes a server running a host application to manage data migration processes by transmitting control commands and/or parameters to the tape drive module. The tape drive module, in response, performs the data migration including data extraction from the source device and data loading onto the destination device. The data path passes between the source and destination devices through the tape drive cards but does not include the server running the host application so that data security is provided by the tape drive module along the entire data path rather than data being at risk in a server.

Abstract: A method for stabilizing magnetic domains in dual stripe magnetic read heads is provided. This method first comprises providing a plurality of coupled magneto-resistive read elements in a spaced relationship. These read elements include top and bottom patterned magnetic shields on ceramic substrates, with two magneto-resistive (MR) sensor elements between the shields, all separated by insulating layers. Magnetic support structures are provided adjacent and separated from the coupled read elements, wherein the magnetic support structures provide a uniform magnetic field that stabilizes the magnetic domains of the MR sensors in the coupled read elements.

Abstract: A magneto-resistive (MR) stripe element includes a magnetically active body portion and a tri-layer electrical conductor structure arranged proximate the magnetically active body portion. The conductor structure has an alpha-Ta bi-layer film and a chromium capping layer. The alpha-Ta bi-layer film includes a chromium base layer and a tantalum layer. The capping layer caps the alpha-Ta bi-layer film such that the tantalum layer is disposed between the chromium base layer and the chromium capping layer. The tri-layer conductor structure has minimized compressive stress after deposition of the three layers and an even lower compressive stress after annealing. The thickness of the chromium capping layer is dependent at least upon the thickness of the chromium base layer such that the tri-layer conductor has a minimized compressive stress after deposition and annealing. The MR stripe element may be incorporated in a magnetic read head for reading data from a magnetic storage medium.

Abstract: An apparatus and method for controlling electrostatic discharge in magnetic tape heads is, provided. This method includes using a conductive adhesive to electrically connect the substrate and closure of each read/write module as well as connect the read/write modules in the head. The conductive adhesive can be used as an adjunct or a replacement for adhesives used during the normal assembly process. The modules are then connected to ground. In one embodiment, the read modules are electrically tied to the write module, which is then connected to ground through a high resistance path.
