| 20120066518 | CANISTER-BASED STORAGE SYSTEM SECURITY - Security is provided for a data set stored in a data storage canister. The data set has a data size when received for storage within the canister. At least one data security operation is performed on the received data set to generate secure data having a secure data size that may be different than the set data size. The secure data is stored on at least one data storage device within the canister. Any information about the secure data size is kept from the data producer sending the data set for storage. | 03-15-2012 |
| 20100165506 | METHOD OF MANIPULATING DATA STORAGE ELEMENTS - A device and method for simultaneously manipulating multiple data storage cartridges or other storage elements in a storage library. The device housing includes an opening for receiving data storage cartridges. A gripping mechanism extends from the opening. The gripping mechanism is adapted to grip a data storage cartridge to be retrieved and to urge the data storage cartridge into the opening. One or more transport mechanisms are attached to one or more inner walls of the housing. The transport mechanisms are adapted such that once a data storage cartridge moves into the opening, the transport mechanisms will urge the data storage cartridge further into the opening until the data storage cartridge is held within the housing. The data storage cartridge can be moved further into the housing such that the gripping mechanism is free to collect additional cartridges. | 07-01-2010 |
| 20100033871 | BI-DIRECTIONAL MAGNETIC RECORDING HEAD BUILT ON A COMMON SUBSTRATE - The aspects of the present invention provide a magnetic recording head, a method for manufacturing a magnetic recording head, and a magnetic recording head drive. The magnetic recording head includes a substrate and a first magnetic device connected to the substrate. The magnetic recording head also includes a second magnetic device connected to the first magnetic device. The first magnetic device is aligned with the second magnetic device. The first and second magnetic devices are supported by the same side of the substrate. | 02-11-2010 |
| 20090213495 | USE OF GRATING STRUCTURES TO CONTROL ASYMMETRY IN A MAGNETIC SENSOR - The present invention provides apparatus and method for controlling the asymmetrical properties of the response of a magnetic sensor element to a magnetic field produced by the digital data in a magnetic storage device. The present invention also provides an apparatus and method for controlling the bias point of a magnetic field produced by a magnetic sensor element. | 08-27-2009 |
| 20090030954 | MANAGEMENT OF MULTIPLE VIRTUAL DATA COPIES - More than two copies of data in a storage management system may be managed by directing at least one virtual volume to a receiving management class within the storage management system. Each virtual volume is exported to a third multi-volume copy, unknown to the storage management system, based on the receiving management class. A manifest file is created listing each exported virtual volume. | 01-29-2009 |
| 20080285181 | METHOD FOR PROTECTING AGAINST CORROSION IN A GMR SENSOR BY PROVIDING A PROTECTIVE COATING OVER AN END OF A COPPER LAYER SPACED APART FROM A DETECTION SURFACE BY A SPECIFIED DIMENSION - A method for providing a giant magneto-resistive (GMR) sensor for use in sensing magnetic flux is provided. The method comprises positioning a layer of Cu material between first and second layers of a specified ferromagnetic material. The respective end surfaces of the Cu layer and the first and second layers are initially located in a common plane and in a co-planar relationship with one another. The method further comprises removing an amount of material from the copper layer to form a new end surface thereof that is selectively spaced apart from the common plane and applying a protective coating to the new end surface of the Cu layer to inhibit corrosion of the Cu layer. | 11-20-2008 |
| 20080263272 | DATA STORAGE MANAGEMENT METHOD - A method for selectively controlling reutilization of space in a virtual tape system (VTS) having a buffer and a multiple volume tape cartridge includes transferring data volume files to the VTS. The buffer transfers the data making up these files as virtual tape volumes (VTVs) to different locations of the cartridge for storage. A file is selectively designated for the VTS to delete from storage after a date included with the file has elapsed by deleting the VTVs corresponding to the file from the cartridge to reuse space of the cartridge. The method includes detecting if a file transferred as VTVs to the cartridge has been designated for deletion. The VTS is prohibited from deleting the file after the date has elapsed if the file was not designated for deletion and is allowed to delete the file after the date has elapsed if the file was not designated for deletion. | 10-23-2008 |
