摘要： The present invention discloses read and write power control methods and system for an optical recording device that records information on an optical disk having read-only areas. The read and write power control methods respectively introduce the steps of determining a specific level of a former power control signal output based on a former power control, and then according to the specific level, setting a predetermined level of a power control signal to induce a present power control for rapidly outputting a proper power of the pick-up head. Accordingly, the level transition of the read/write power control signal can be shortened and even eliminated. An unstable read/write power output for the pick-up head can be avoided.

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.
