| 20090006891 | Apparatus, System, and Method for Hard Disk Drive Redundancy - 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. | 01-01-2009 |
| 20090196988 | HOLOGRAPHIC DISK WITH 2P TRACK-BEARING LAYER - A method for forming a holographic storage media, including: applying a liquid photopolymer to a substrate of glass, quartz, or polycarbonate, the substrate having a first surface; engaging a stamper with a negative of desired tracks on the liquid photopolymer; curing the liquid photopolymer with ultraviolet light creating a plurality of tracks; applying a reflective layer to the plurality of tracks; applying a gap layer to the plurality of tracks; applying a dichronic mirror layer to the gap layer; and applying a holographic storage layer to the dichronic mirror layer. | 08-06-2009 |
| 20090201243 | METHODS AND SYSTEMS INVOLVING DIURNAL COMPUTING - A method for controlling a computer system comprising, determining an ambient light level, starting a lighting device operative to illuminate an input device responsive to determining that the ambient light level is below a threshold value, and stopping the lighting device responsive to determining that the ambient light level is above the threshold value. | 08-13-2009 |
| 20090201782 | HOLOGRAPHIC DISK WITH OPTICAL-NOTCH-FILTER LABEL - A holographic disk, including: a holographic recording layer and a servo-tracking layer, the holographic recording layer separated from the servo-tracking layer by a dichroic mirror that prevents a data I/O laser from accessing the servo-tracking layer while allowing a servo-tracking laser to access embedded servo tracks; a transparent cover layer including at least one layer of optical notch filter that forms a label, the optical notch filter blocking light at a wavelength different from the data I/O laser and the servo-tracking laser; where the label is a color label including at least one of numbers, letters, descriptive figures, pictures, and barcodes. | 08-13-2009 |
| 20100032530 | AUGMENTED TRACK TO FACILITATE REMOVAL OF STIFFENING LAYERS FROM A CABLE RETAINED IN THE TRACK - An apparatus to support a cable is provided and includes a channel shaped track, in which the cable is retained, which is formed to define a plurality of pairs of holes on opposing sides of the track at substantially equal intervals and slots that each extend from respective tops of each of the holes to an exterior surface of the track, and a plurality of support members, each of which extends across the track and between at least a portion of adjacent pairs of the holes, to thereby be respectively positioned to prevent the cable from propagating toward the exterior surface of the track. | 02-11-2010 |
| 20100121825 | FILE SYSTEM WITH INTERNAL DEDUPLICATION AND MANAGEMENT OF DATA BLOCKS - A method for deduplicating and managing data blocks within a file system includes adding a deduplication identifier to each pointer pointing to a data block to indicate whether the data block is deduplicated, detecting duplicate data blocks, determining whether one of the duplicate data blocks has been deduplicated, when detected, determining that one duplicate data block is a master copy when it is determined that one duplicate data block has been deduplicated, selecting one of the duplicate data blocks to be a master copy when it is determined that the duplicate data blocks have not been deduplicated, and setting the deduplication identifier of the selected duplicate data block to indicate deduplication, and determining that the other duplicate data block is a new duplicate data block and setting the deduplication identifier of the other duplicate data block to indicate deduplication and directing the respective pointer to the master copy. | 05-13-2010 |
| 20100177885 | METHODS TO FACILITATE ENCRYPTION IN DATA STORAGE DEVICES - Methods are provided for managing data encryption for a data storage library. An implementation assessment is performed for a customer and, in response to the implementation assessment, a set of customizations are generated for an encryption command communications appliance to enable the appliance to communicate with an encryption-capable storage device and a data storage library controller within the data storage library and with an encryption key manager (EKM) coupled to the data storage library. The encryption command communications appliance is configured with the set of customizations and the configured encryption command communications appliance is installed in the data storage library coupled to the library controller, the storage device and the EKM. | 07-15-2010 |
| 20110102938 | POWER MODE OPERATION OF A MAGNETIC TAPE DRIVE - A magnetic tape drive having a tape drive system for moving magnetic tape, tape read/write and servo system, tape cartridge load/unload systems, I/O communications, memory; and a control system, operates in three modes to conserve energy consumption. A first low power mode powers the I/O communications, the memory, and the control system. If a magnetic tape cartridge is in loaded position in the magnetic tape drive, the second low power mode powers the same as the first low power mode, and additionally powers the tape drive system to apply tension to a magnetic tape of the magnetic tape cartridge. In the first and the second low power modes, the control system operates the I/O communications, the memory and the control system to respond to and execute commands received at the I/O communications if the commands are executable without magnetic tape access. The third, full power mode, is entered if a command received at the I/O communications requires magnetic tape access. | 05-05-2011 |
