摘要： A writing method for a multilayer optical disc. The method includes: measuring and recording optimum internal gains obtained when the objective lens is located on each inner side of the pick-up head, respectively, checking the writing direction based on the specific writing direction on each data layer of the disc, selecting the inner optimum internal gain when the writing direction is toward outside, and selecting the opposite inner optimum internal gain when the writing direction is toward inside to minimize the offset of the tracking error signal.

摘要： A writing method for an optical disk drive includes receiving a command to write a disc; implementing an optimum power control (OPC) test for a predetermined data transfer rate to obtain a relation of a beta parameter to writing power; acquiring a writing power for the predetermined data transfer rate with a target beta parameter; calculating the energy area ratio of writing strategies for every data transfer rate; multiplying the energy area ratio by the writing power for the predetermined data transfer rate to produce the writing power for every data transfer rate; and compensating the writing power with automatic writing control.
