| 20080262658 | Vibration Compensation Based on Identification of Vibration Frequency - A shock detection circuit housed in an electronic device includes an output shock signal that is indicative of vibration amplitude. To compensate for vibrations that are experienced by the electronic device, the output shock signal is analyzed. The analysis of the output shock signal allows a vibration frequency of the output shock signal to be identified and used in vibration compensation. | 10-23-2008 |
| 20080284074 | Shock Absorber Capable of Damping Vibration - A shock absorber is provided that also includes vibration damping. The shock absorber includes at least one shock absorbing frame member that partially surrounds an electronic device enclosure. The shock absorber also includes at least two protrusions that protrude from the at least one shock absorbing frame member. Each protrusion extends beyond the at least one shock absorbing frame member from a recessed surface recessed into the at least one shock absorbing frame member. | 11-20-2008 |
| 20080304172 | DATA STORAGE MEDIUM HAVING SYSTEM DATA STORED IN A GUARD BAND BETWEEN ZONES OF CONSECUTIVE DATA STORAGE TRACKS - A storage medium format is provided having a first band of a plurality of consecutive data storage tracks having user data stored thereto, a second band of a plurality of consecutive data storage tracks having other user data stored thereto, and a guard track medially disposed therebetween the first band and the second band and having system data stored thereto. | 12-11-2008 |
| 20090003146 | SERVO GAIN ADJUSTMENT BASED ON BIAS FORCE ERROR - Apparatus and related methods are described for adjusting servo gain. In an exemplary apparatus, a circuit determines a bias force error that occurs between an estimated bias force and an actual bias force on an actuator during movement by a servo motor. The circuit adjusts a servo gain in response to the bias force error, and regulates movement of the actuator by the servo motor in response to the servo gain. | 01-01-2009 |
| 20090089603 | STORAGE DEVICE MAINTENANCE IN A PORTABLE DEVICE BASED ON A POWER EVENT - The disclosure is related to monitoring a portable electronic device to detect an occurrence of a power event. A command can be sent to a data storage device to initiate a maintenance procedure on the data storage device. In a particular embodiment, a method includes monitoring a portable electronic device to detect an occurrence of a power event. The method also includes selectively sending a command to a data storage device to initiate a maintenance procedure on the data storage device when the occurrence of the power event is detected. | 04-02-2009 |
| 20090128945 | DATA PROTECTION BASED ON SYSTEM VIBRATION MODES - An aspect of the present disclosure relates to implementing a data protection mode based on system vibration modes in a data supported system. An exemplary system vibration mode is associated with an operating mode of the data supported system. The data protection mode operates to limit, or prevent, errors caused by the vibration. In one exemplary embodiment, a method is provided for operating a data supported system. The method includes receiving an indication that a vibration associated with an operating mode of the system will occur and, in response, implementing a data protection mode in the system. | 05-21-2009 |
| 20090128946 | DISCONTINUOUS MODE BACK EMF MEASUREMENT - A terminal voltage of an actuator motor is measured while the actuator motor is in a high impedance state. An internal voltage of the actuator motor is measured, and a back-EMF voltage of the actuator motor is estimated in response to the terminal voltage of the actuator motor and the internal voltage of the actuator motor. A drive current supplied to the actuator motor is controlled in response to the estimated back-EMF. | 05-21-2009 |
| 20100313076 | SCANNING REASSIGNED DATA STORAGE LOCATIONS - An aspect of the present disclosure relates to scanning reassigned data storage locations. In one example, a reassignment table is accessed to identify a deallocated data storage location and scan the deallocated data storage location for media defects. | 12-09-2010 |
