摘要： A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of servo sectors defining a plurality of servo tracks. The servo tracks form a plurality of servo zones. A disk locked clock is synchronized relative to a servo data rate of the servo zone the head is over. A first reader/writer gap is measured in cycles of the disk locked clock at a first servo track in the first servo zone. A second reader/writer gap is measured in cycles of the disk locked clock at a second servo track in the second servo zone. The first and second reader/writer gaps are normalized to generate a normalized first and second reader/writer gaps. A third reader/writer gap is estimated in cycles of the disk locked clock at a third servo track in the second servo zone based on the normalized first and second reader/writer gaps.

摘要： A disk drive is disclosed comprising a disk comprising a plurality of servo sectors defining a plurality of servo tracks. The servo tracks form a plurality of servo zones, where a servo data rate of servo sectors in a first servo zone is different than a servo data rate of servo sectors in a second servo zone. A servo control system servos a head over the disk. An estimated servo state of a servo control system is generated, and when the head crosses from a first servo zone to a second servo zone, the estimated servo state is adjusted to compensate for a transient in a circumferential distance between a servo sector in the first servo zone and a servo sector in the second servo zone.

摘要： Systems and methods electrically connect a first electronic device or electrical component, having a external electrical connector, to a circuit board of a second electronic device. A low-cost, user-installable connection system isolates mechanical stresses imposed on the external electrical connector to within the user-installable connection system, thereby preventing the mechanical stresses from reaching the circuit board in the second electronic device. If the connection becomes faulty, only the low-cost, user-installable connection system must be replaced.

摘要： An improved system and method for pen-based handwritten and keystroke data input into a computer system is disclosed. The system and method receives pen-based data entry from multiple related input boxes within a handwriting area on a digitizer pad. Thread-based processing allows each input box or group of input boxes to be separately evaluated, providing for continuous character recognition. Character strokes entered into each input box or group of input boxes are saved and interpreted together to allow more complete recognition of naturally written characters. Improvements on keyboard layouts are also disclosed.
