摘要： An apparatus includes an amplifier that employs a bias current to drive a print nozzle. A current reduction module can be employed to offset the bias current and to reduce a portion of the bias current from appearing in a subsequent stage to the amplifier in order to mitigate power in the subsequent stage.

摘要： A system provides a signal to an actuator within an optical pickup unit of an optical disk drive. In one implementation, SUM signal data (an output from the quad sensors typically present in the optical pickup unit) is recorded within a SUM table. An error term generator processes the SUM signal data from the SUM table to produce an error term. An actuator control signal generator generates a signal to control movement of the actuator, wherein the signal is a function of a prior actuator position, the error term and an adaptation coefficient, wherein the adaptation coefficient impacts a rate at which the error term is allowed to modify the prior actuator position.

摘要： Focus calibration in an optical drive. Optics are moved with respect to a disc in the optical drive. A first interface of the disc is optically detected at a first distance, and a first drive signal value is detected at the first interface. A drive signal change is determined using a second drive signal value at a second distance. A gain is determined using the drive signal change and a thickness associated with the first and second distances.

摘要： An optical disc drive is has a voice coil motor that carries and moves focal optics to focus a laser beam onto an optical disc The voice coil motor is responsive to input signals which are based on a calibrated temperature. A temperature measurement is made at the voice coil motor for an operating temperature, and a difference is calculated between calibrated and operating temperatures. The temperature differences are used to calculate adjustment in input signals used to drive the voice coil motors.

摘要： A method for calibrating an interferometer uses an actuator adapted to control an optical gap in response to application of an electrical signal. The interferometer is illuminated with a beam of light having a predetermined substantially monochromatic wavelength, oriented at a first predetermined angle of incidence, and light reflected from the interferometer at a second predetermined angle is detected while varying an electrical signal applied to the actuator, thereby establishing a calibrated relationship between the applied electrical signal and an optical path length of the interferometer.
