摘要： An optical reading/writing apparatus has an optical head that includes a collimator and a lens. For focusing control, a startup procedure is executed to generate a first startup S-curve. A boundary is then set according to the startup S-curve. After executing focusing on and tracking on, a plurality of position combinations of the collimator and the lens are selected for focusing calibration, thereby obtaining respective focusing error signals. By comparing the focusing error signals with the boundary, whether the position combinations of the selected collimator and the lens are valid can be determined. One of the valid position combinations with the greatest image-quality value is then selected to read/write the optical disc in the subsequent reading/writing procedure.

摘要： A method and system for obtaining focus optimization in an optical disc system is disclosed. The focus offset of a recording unit is set to a first of a plurality of predetermined values. A HF quality value is measured and stored for the selected focus offset value of the recording unit. The focus offset is then set to a best-known focus offset value. Tracks on the optical media being read are then jumped. The above steps are then repeated for each of the plurality of predetermined focus offset values. The optimal focus setting is then determined from the stored HF quality measurements.

摘要： An optical disk drive and a method for determining a disk type are described. The optical disk drive may be arranged to receive a radial error signal while an incident beam is focused onto the optical disk and before tracking the track, to analyze the radial error signal for detecting whether a wobble signal is present, indicating whether the track is wobbled, and to derive a disk type from the wobble signal, if present. The optical disk drive may additionally or alternatively be arranged to receive a central aperture signal while the incident beam is focused onto the optical disk and before tracking a track including a sequence of embossed pits, to analyze the signal amplitude of the central aperture signal, and to determine the disk type from at least a first variation of the signal amplitude of the central aperture signal as a function of time.
