摘要： The present invention relates to a method for operating an optical drive system (12) capable of reproducing/recording information from/to an optical carrier (1), wherein the optical drive system includes a focus controller (PID) for controlling a focus actuator (4), and a focus memory loop (ML) for applying a stored correction signal to the focus actuator (4). The method aims at avoiding impacts between the focussing means (3) and the optical carrier (1), by gradually stopping the focus control loop in response to an event, such as a user initiated ejection of the optical carrier. The gradual stop of the focus control loop is achieved by gradually reducing a memory loop parameter of the focus memory loop (ML), and by gradually reducing a controller parameter of an integrating part (I) of the focus controller (PID). It is an advantage of the invention that the phase of the stored correction signal is synchronized with the angular position of optical carrier (1) during the gradual stopping.

摘要： The present invention discloses an optical apparatus capable of reproducing/recording information from/to an optical carrier, e.g. a DVD or BD disk. The apparatus has control means for positioning/focusing a radiation beam (5) on the carrier and photo detection means for detection of radiation reflected from the carrier. Additionally, defect detection means (DEFO) for detection of surface defect areas (A1, A2) can indicate where surface defects, e.g. scratches etc., are present. Processing means are adapted for integrating, and preferably differentiate, error signals (RE, FE) immediately after the beam (5.b) is exiting a defect area (A1) for generating adaptive control signals (AD_RE, AD_FE). The optical system is adapted to apply the adaptive control signals (AD_RE, AD_FE) when the beam is positioned in the defect area (A1) again, thereby reducing off-track deviation as the beam (5.d) exits the defect area (A1).

摘要： In a method and device for performing tilt control, a focus and a tilt controlling output is generated, and a focusing and tilt state of an optical recording/reproducing beam is controlled by determining a radial tilt value based on a differentiation of focus control values obtained at different radii of said optical disk (1). The combination of, e.g., a 3D actuator with the dz/dr tilt measurement provides the advantage that focus and tilt adjustment can be performed in the same element. Thereby, influences or measurement variations caused by environmental conditions and/or circuit characteristics can be minimized to reduce compensations requirements. Furthermore, a 3D actuator (11) with a split coil arrangement may be used to provide a three-dimensional focus adjustment. Thereby, the 3D actuator (11) can be used for feed-forward tilt compensation without offset or gain errors and without any additional sensor.

摘要： An optical playback or recording device is equipped with mass-unbalance detection means (20) for detecting unbalance on the record carrier (2). Mass-unbalance causes vibration and sound in the optical device when the record carrier (2) is rotated at a relatively high speed. When mass-unbalance is detected, the speed may be reduced to reduce the vibration and sound in the optical device. The mass-unbalance detection means (20) performs the following steps to detect mass-unbalance: a) determining the maximum value Umax1 of the actuator control signal (AS) at a rotational speed Ω1; b) determining the maximum value Umax2 of the actuator control signal (AS) at a rotational speed Ω2; c) comparing Formula (I) with Formula (II). If these values are substantially equal, then the effect of mass-unbalance is small, otherwise the effect of mass-unbalance is too great and the speed may have to be reduced U max 1 ω 1 2 with U max 2 ω 2 2 .

摘要： A device is for scribing a visible label on the medium. The medium (11), for example an optical disc, has a label side provided with a radiation sensitive layer for creating the visible label via a beam of radiation. The device has a head (22) and a positioning unit (25) for radially positioning a scribing spot, which unit has a course positioning system by movements of the head and a fine positioning system. The device has a generator unit (32) for, during at least one boundary trace of the substantially parallel traces which precedes or succeeds a head movement, temporarily applying a broadening signal (35) to the fine positioning system for broadening the boundary trace in the transverse direction. This has the advantage that unwritten annular areas called white bands, which may occur due to mismatch of the head movement and the fine positioning system, are reduced or prevented.

摘要： The present invention relates to a method for operating an optical drive system capable of reproducing/recording information from/to an optical carrier (30), wherein a position error and a speed error of a radiation spot (12, 53) on the carrier has been created due to an unreliable error signal which has been generated due to a surface defect (52). The method includes the steps of registering values of e.g. servo signals, determining the occurrence of a defect using a defect detector DEFO (22), generating a first and a second compensation signal and applying these compensation signals to the control system (10) of the optical drive system. The first compensation signal is capable of reducing the speed error and the second compensation signal is capable of reducing the position error. Thus, the application of the compensation signals immediately after the unreliable error signals reduces the position error and the speed error of the focussed radiation spot (12, 53).
