摘要： A method for determining an optimum recording condition of an optical recording/reproducing apparatus is used for recording data into an optical disc. Data is first written into a plurality of test regions of the optical disc under a plurality of recording conditions, respectively. The data written into the plurality of test regions are converted into radio-frequency (RF) signals. The RF signals are Viterbi-decoded to obtain corresponding path metric increase rates. The path metric increase rates are used to determine an optimum recording condition.

摘要： A method for controlling read power and an open-loop read control device using the same. The open-loop read control device is used in an optical disk writer and includes a memory, a DAC and an amplifier. The optical disk writer includes a pickup head device having a laser diode. When writing is disabled, the read power of the optical disk writer for reading the disk corresponds to a specific voltage. The memory stores a relationship curve and outputs a corresponding reference value corresponding to the specific voltage. The DAC converts the corresponding reference value into an analog corresponding reference value. The amplifier receives the analog corresponding reference value and outputs a read power control voltage, which controls the laser diode to generate a substantially constant read power in the write process.

摘要： A condition of a recording pulse comprising a top pulse and a following pulse is determined in a predetermined order. In some embodiments, an mT pulse condition is first determined by test recordings with various power and pulse conditions, involving an inspection of recording quality; then an m′T/(n−m)T ratio is determined by test recording under the mT pulse condition fixed; and finally an nT pulse is configured based on the ratio. A phase shift can be corrected by test recording with the nT pulse.

摘要： A tilt adjustment device for adjusting tilt of a left guide bar with respect to a right guide bar, and includes a holding seat and a cylindrical-shaped bushing disposed rotatably within the holding seat. The bushing defines a bar-retention hole to permit extension of the left guide bar theretrhough, and has a turning portion defining a first axis and an insert portion that extends eccentrically from the turning portion and that defines a second axis parallel to the first axis. Rotation of the cylindrical-shaped bushing relative to the holding seat results in a radial movement of the turning portion, which, in turn, moves the first axis toward and away from the second axis of the insert portion.
