摘要: An apparatus and method for reducing optical source noise other common-mode system in a data signal read from an storage medium. exemplary accordance with one aspect of the present invention includes first detector to generate by detecting return beam resulting application radiation medium; second monitor providing beam; correction circuit adapted receive corrected therefrom; means controlling gain path at least response to, example, low-frequency amplitude differences between signal. One or more delay lines may be included provide phase matching input.
