Individual adjustment of pit and land transition locations in an optical disc mastering process

摘要

In an optical disc mastering process in which a master disc is generated, an apparatus comprising
a master driver circuit (300), operably connectable to a signal processing system which generates a modulation signal to modulate a writing beam, comprising:
a latch (308) for receiving and temporarily storing successive portions of the modulation signal; and
a master oscillator (310), operably coupled to the latch, which generates and supplies a master clock at a selected frequency to the latch to reclock the modulation signal at the selected frequency of the master clock.
