摘要： The present invention discloses a tilt adjustment system and method of an optical disk device with a pickup head, which includes a decoder for decoding the encoded information from an optical disk and checking whether error occurs during decoding. A decoding error calculator calculates a statistics corresponding to the decoding errors under the different tilts of the pickup head. A tilt control unit utilizes a specific algorithm to determine a decoding error rate, which is minimal than the other error rates within the statistics. Thus, an optimal tilt value can be decided upon the minimal error rate to adjust the tilt of the pickup head.

摘要： Methods and apparatuses for generating a protection window signal for use in header detection of an optical storage medium are disclosed. One of the methods involves: extracting a maximum level of an RF-sum signal derived from the optical storage medium to generate a first level value; extracting at least one of DC level and bottom level of the RF-sum signal to generate a corresponding second level value; calculating a reference level according to the first and second level values; and comparing the RF-sum signal with the reference level to determine a protection window signal. When the accessing of the optical storage medium is switched from a first area with a first reflectivity to a second area with a second reflectivity, the response speed of extracting the DC level/bottom level of the RF-sum signal, the weighting of the second level value, or the DC level of the RF-sum signal is adjusted.

摘要： The invention provides a method for determining the layer type of a blu-ray disk. First, a laser beam is focused on a target layer of the blu-ray disk. Reflection of the laser beam from the target layer is the detected to obtain a reflection signal. The reflection signal is then processed to generate a first tracking error signal and a second tracking error signal. Magnitudes of the first tracking error signal and the second tracking error signal are then measured. The magnitude of the second tracking error signal is then subtracted from the magnitude of the first tracking error signal to obtain a difference value. Finally, the layer type of the target layer is determined by comparing the difference value with the first predetermined threshold.
