Controller and method employed in optical storage apparatus for generating control signals each having minimum transmission pulse length corresponding to more than one power symbol period

摘要

A controller of an optical storage apparatus for generating a plurality of control signals is provided. The controller includes a code generator implemented for determining a plurality of control codes according to an input data associated with data recording, and generating the control signals to deliver the control codes. Each of the control codes represents one power level. Besides, regarding each of the control signals, a minimum transmission pulse length thereof corresponds to more than one power symbol period.
