摘要：
An optical storage system modulates a laser beam based on a high frequency modulation (HFM) signal and a pattern to be recorded on an optical storage medium. At least one of an amplitude and a frequency of the HFM signal is adjusted when using the light beam to record the pattern on the optical storage medium or read data from the medium.
