摘要： The invention relates to a data storage device (101) which comprises a data interface (103) for reading data from a spinning data storage disc (105). The data storage device (101) comprises a motor (111) for spinning the data storage disc (105) at a desired speed. The data storage device (101) further comprises a speed change processor (115) for determining a preferred motor speed change time; and a motor controller (113) for controlling the motor (111) to perform the speed change in response to the preferred motor speed change time. Specifically, the preferred motor speed change time resulting in the lowest energy consumption for disc spin-up and jump operations are determined, and the motor (111) is controlled to change the speed substantially within the preferred motor speed change time. The invention is particularly suitable for Small Form Factor Optical (SFFO) disc systems and allows for reduced energy consumption and thus increased battery life.

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 invention relates to a pickup unit (1) for reading and/or writing data on a disk (2). The pickup unit comprises a base (5), a lens (3) in a lens holder (4) which is suspended from the base (5) and which is movable in at least a focusing direction of the lens (3), a pullback arrangement (9), and/or a locking arrangement (12, 12'). The pullback arrangement (9) and the locking arrangement (12, 12') are adapted to act on the lens holder in order to prevent collisions between the lens (holder) and the disk, the pullback arrangement (9) is adapted to pull the lens holder (4) into an inoperative position remote from the disk, while the locking arrangement (12, 12') is adapted to subsequently lock the lens holder in the inoperative position. In this manner collisions due to strong external mechanical forces or pulses exerted on the pick up unit can be effectively prevented.

摘要： Conventional accelerometers are based on test masses that are suspended in some kind of spring damper system. According to an exemplary embodiment of the present invention, a two-dimensional adaptive accelerometer based on dielectrophoresis is provided, which measures an acceleration of a test mass freely floating in a medium by determining the movement of the test mass due to an accelerating force acting on the test mass. A non-uniform electric force field provides for a wide and adjustable dynamic range.

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.
