摘要： A record carrier has pattern of substantially parallel tracks constituting a data area, and a first and second boundary mark on predefined transverse positions bordering the data area. An optical disc drive scans the record carrier via a beam of radiation (24) from a head (22). The device has a control unit for determining a position of a selected track, and a tracking system for positioning the head on the selected track via a jump by a motor (40) that moves the head transverse to the tracks. The device has a head range unit (32) for detecting the boundary marks via the beam and controlling the motor for limiting said transverse movement of the head to a head range corresponding to the data area bordered by the boundary marks. Hence the motor is stopped (48) to prevent the head from exceeding head range corresponding to the data area without position sensors or mechanical elements.

摘要： An optical disc drive scans selected tracks on a record carrier via a beam of radiation (24) from a head (22). The head is positioned on the track by a tracking system. The tracking system includes a main servo loop, constituted by a motor (40) for moving the head along a rail (46) transverse to the tracks, position means (41) for generating a position signal in dependence of an actual position of the head, and an amplifier (44) generating a driving signal coupled to the motor. The amplifier has an adjustable gain that is set in dependence on a friction profile. The device has a memory (34) for storing the friction profile as determined during a calibration process. By compensating friction of the rail a reliable response of the tracking system to jump commands is achieved. Power dissipation is reduced because the driving signal as generated is just strong enough to move the head along the rail.

摘要： An optical disc drive scans tracks on a record carrier via a beam of radiation (24) from a head (22). The head is positioned on a selected track by a tracking system. A motor (40) moves the head transverse to the tracks in dependence on a position signal, which is generated in dependence on a number of revolutions of the motor. A control unit (20) determines a distance of moving the head based on the position of the selected track and a current position of the head. An accurate track pitch ratio is retrieved from the record carrier to calculate the distance to be moved. A memory (34) stores a motor transfer rate as determined during a calibration process, which motor transfer rate indicates a number of revolutions of the motor for a predefined moving distance. The motor transfer rate enables translating the positions as determined and a distance to move the head into in revolutions of the motor.

摘要： The present invention discloses an electronic device (1) comprising an optical device (10) having a container enclosing an insulating liquid (A) and an electrically susceptible liquid (B), the insulating liquid (A) and the electrically susceptible liquid (B) being immiscible and being in contact with each other via an interface (14), at least one of the liquids (A; B) being at least partially placed in a light path through the container. The electronic device further comprises first signal generating means (34) for generating a control signal indicative of a difference between the actual position of the interface (14) and a desired position; second signal generating means (50) for generating a further control signal for adapting the position of the interface (14) in response to the control signal; and control means (40) for prohibiting the second signal generating means (50) to update the further control signal during a positional change of the interface. Consequently, it is avoided that an update of the further control signal, e.g. a driving voltage of the optical device, is based on a control signal, e.g. a focus error signal, derived from an unstable interface (14).

摘要： A controllable optical lens system, comprises a chamber housing first and second fluids, the interface between the fluids defining a lens surface. An electrode arrangement controls the shape of the lens surface and has first and second electrodes. A parameter is determined by the system dependent on the electrical resistance through at least one of the lens fluids between the first and second electrodes. Thus, the series resistance through a lens fluid is used as a measure of meniscus position.
