Latest Patents

David C Robbins holds a patent for an "Automatic velocity calibrator for a velocity servo loop in a magnetic disk drive." This invention allows for a velocity calibration in a single pass over the magnetic disks by measuring actuator velocity and adjusting the gain of the velocity transducer through a series of successive approximations. The process involves turning a timer on in response to a track crossing and turning it off after detecting at least two successive track crossings. A plurality of velocity measurements are stored and averaged, and the average velocity is compared to a constant velocity command. An 8-bit latch is then incremented or decremented based on this comparison, while a digital to analog converter produces a reference for an automatic gain control amplifier in the servo system, which adjusts the velocity transducer gain.
