ABSTRACT:
An exemplary method for optimizing a recording signal of an optical recording apparatus to record data onto a disc, the recording signal having a first pulse-width parameter, the method includes selecting an initial value of the first pulse-width parameter; generating adjusted values based on the initial value to record test data onto the disc respectively; measuring mark lengths of lands; determining average lengths of the mark lengths of lands; determining differences between the average lengths and a predetermined standard length; linear curve fitting the adjusted values and the differences employing the following linear curve fitting equation: Y=AX+B to obtain the constants A and B, wherein X represents the adjusted values, Y represents the differences; determining and storing an optimum value of the first pulse-width parameter to be used for recording the data onto the disc, this optimum value equals to −B/A. An optical recording apparatus is also provided.
