20080272222 | METHOD FOR REDUCING OCCURRENCES OF TAPE STICK CONDITIONS IN MAGNETIC TAPE - Disclosed is a method for reducing occurrences of tape stick conditions in magnetic tape, the method including stopping functional rotation of each of two bi-directionally rotatable reels of a reel-to-reel tape drive that includes a length of magnetic tape at least partially wound around each reel, a portion of the length of tape extending between the two moveable reels and contacting a head positioned between the two reels; wherein the stopping creates a stop condition in the tape drive, actuating a fractional rotation at least one of the two bi-directionally movable reels a fraction of a reel turn in a first direction during the stop condition, causing the portion of the length of tape to at least temporarily break contact with the head via the fractional rotation, and re-starting functional rotation of each of the reels, ending the stop condition via the re-starting. | 11-06-2008 |

TUCSON AZ USAANM OGURA; EIJIAACI KANAGAWAAACO JPAAGP OGURA; EIJI KANAGAWA JP - In a tape drive having a rotatable take-up reel supporting an end of an elongate tape, a drive control system for rotating the take-up reel and for rotating a tape supply reel of a removable tape cartridge. The drive control system is arranged to tension and move the elongate tape between the reels. At rewind, the drive control system rewinds the elongate tape onto the supply reel at rewind velocity under tension; upon the rewinding approaching the end of the elongate tape, rewinds the elongate tape at a reduced velocity under tension, the reduced velocity less than 60% of the rewind velocity; and stops the reduced velocity rewinding for a period of time and maintains the elongate tape in a dwell state under tension which is greater than an operating tension during tape motion. The dwell state time period may be substantially 10 seconds. | 01-17-2013 |
20140237269 | ESTIMATING POWER USAGE IN A COMPUTING ENVIRONMENT - Power usage is estimated in a computing environment by automatically detecting hardware configuration information by use of a software agent that is translated into power consumption information for implementing a plurality of power estimation models for efficient power consumption and utilization. | 08-21-2014 |

20140240865 | DYNAMICALLY CONTROLLING MAGNETORESITIVE BIAS - Magnetoresistive (MR) bias is dynamically controlled in a tape drive using a processor device. Median tape head amplitude is monitored during a calibration operation, as measured across all tracks of the tape head, against predetermined thresholds of the tape drive for determining if the median tape head amplitude is below the threshold value. Upon determining the median tape head amplitude is below the threshold value during the calibration operation, a reference MR bias and a MR bias range is dynamically adjusted, during the calibration operation, for increasing the median tape head amplitude. | 08-28-2014 |

20080215986 | DEVICE DIRECTED USER INTERFACE ELEMENTS FOR DATA HANDLING SYSTEM MANAGEMENT CONSOLE GRAPHICAL USER INTERFACE - A management console managing a data handling system stores user interface panel elements, and an attached device sends directions to the management console to select at least one of the stored user interface panel elements for a graphical user interface (GUI) panel for the device. The device sends directions to the management console to correlate at least one device command for the device to the GUI panel for the attached device; and the management console generates GUI panel(s) employing the selected user interface panel element(s); and calls commands in response to operation of inputs to the GUI panel(s), the correlated command being available to be called. Further, the attached device(s) send directions to the management console as to labeling of the GUI panel for the attached device; and the management console inserts label(s) in the user interface panel element per the labeling directions. | 09-04-2008 |
20080282172 | DYNAMIC GUI RENDERING BY AGGREGATION OF DEVICE CAPABILITIES - Provided are techniques for rendering a Graphical User Interface (GUI). A device capabilities set is obtained from a device. A rendering package that corresponds to the device capabilities set for the device is selected. The GUI is generated using the rendering package and the device capabilities set. The GUI is displayed to a user on a user interface to enable the user to manage the device. | 11-13-2008 |
20090302143 | APPLYING WHIP EFFECT TO MAGNETIC TAPE EXHIBITING A TAPE STICK CONDITION - As the result of a tape stick condition of magnetic tape with respect to a tape head, the supply reel and the take-up reel apply a base tension to the magnetic tape therebetween of substantially less than a full tension that occurs when the tape is running, and one reel varies the applied tension greater than and less than the base tension by an amount less than the base tension. The variation of the applied tension comprises first applying the greater tension and in succession, second, applying the less tension, comprising a whip effect. The whip effect may be in accordance with a sine wave. The varied tension is less than the base tension to maintain positive tension. | 12-10-2009 |
20100020662 | Automatic Unthread to Secure Tape From Sticking to the Head - A system and method for automatically unthreading a tape. The system and method determine whether the drive being at the stop state could cause the tape sticking condition in future after a defined dwell time (e.g., 20 minutes). The tape sticking tends to increase with time and humidity. Moreover, it is known that worn tape is stickier than new tape. With a plurality of attempts (e.g., four attempts) of moving tape (e.g., every 5 minutes), the drive is able to identify whether the tape needs to be unthreaded. Such a system allows a tape drive to handle the tape in safety at severe condition for the sticking tape, and minimize the penalty for the response to the command in normal condition. | 01-28-2010 |
