A circuit records data on an optical disk while the disk is rotated at a constant angular velocity (42). A velocity detector determines a velocity of a rotating disk as a detected velocity (53). A memory stores sets of write signal control values, and each set of write signal control values is associated with a predefined velocity (148). A control circuit retrieves at least two sets of write signal control values based on the detected velocity and selected predefined velocities of the sets of write signal control values (30). A write strategy circuit generates one or more write signals in accordance with the write signal control values of the selected set and write data (162). The control circuit designates a selected set of write signal control values from the at least two sets of write signal control values while generating the one or more write signals.
