| 20080227571 | Tennis backboard - The invention provides a new tennis backboard design. The backboard includes a firm backing layer underlying a soft deadening layer. The rebound of a tennis ball from the backboard is reduced as compared to rebound from a rigid hard-surface backboard. This allows a player to stand fairly close to the backboard, which reduces misses. The player can stand fairly close and hit balls hard against the backboard. Because the rebound is reduced, the ball simply bounces back softly and easily to the player, allowing the player to hit hard again from a fairly short distance. Thus, long rallies without missing are easily achieved. Since the bounce is reduced, the player can stand closer to the backboard, and therefore the backboard can be smaller than conventional backboards without the player missing the backboard. This allows the backboard to be light, portable, and easily stored. Because of the addition of a soft deadening layer, the firm backing layer of the backboard can also be thin and made of lighter and weaker material than a conventional backboard, reducing the weight of the backboard. | 09-18-2008 |

| 20130286503 | HEAD WRAP PROCEDURE - A method according to one embodiment includes detecting a signal originating from at least one reader of a first outer module of a head as a tape passes thereacross, the head having at least the first outer module and a second outer modules positioned on opposite sides of an inner module and aligned with the inner module in a direction of tape travel thereacross. A first guide positioned in front of the first outer module is moved in a direction towards the tape until the signal detected by the first outer module decreases. The first guide is moved in a direction away from the tape to a position to set about a predetermined wrap angle of the tape relative to the first outer module after the signal detected by the first outer module decreases. | 10-31-2013 |
| 20140185161 | HUMIDITY AND TEMPERATURE CONTROLLED TAPE DRIVE CLEANING - In one embodiment, a method includes receiving at least one of temperature information and humidity information about an environment in which a tape drive resides, performing an analysis of the at least one of temperature information and humidity information, making a determination whether to modify a cleaning cycle based on the analysis of the at least one of temperature information and humidity information, and making a selection and/or modification of a timing of a cleaning operation of the tape drive based on the determination. | 07-03-2014 |
| 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 |
| 20140307346 | HUMIDITY AND TEMPERATURE CONTROLLED TAPE DRIVE CLEANING - In one embodiment, a method includes making a determination whether to modify a cleaning cycle, e.g., of a tape drive, based at least in part on at least one of: an age of one or more tapes, a type of one or more tapes, and an identity of a vendor of one or more tapes. A selection and/or modification of a timing of a cleaning operation is made based on the determination. | 10-16-2014 |
| 20150078148 | EXTENDED DIAGNOSTIC OVERLAY CONTROL FOR TAPE STORAGE DEVICES - A method according to one embodiment includes monitoring a plurality of parameters relating to operation of a tape drive to collect data from the operation of the tape drive. A specification of one or more of the parameters to log during one or more collection windows is received. At least some of the data collected from the operation of the tape drive is logged to a memory during the one or more collection windows, where the at least some of the data collected is stored in a plurality of fields. The method further includes dynamically overlaying one or more of the fields with data corresponding to the one or more specified parameters. | 03-19-2015 |

| 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 |
