METHODS, OPTICAL RECORDING APPARATUS USING SUCH METHODS AND OPTICAL RECORDING MEDIUM FOR USE BY THE METHODS AND THE APPARATUS |
摘要 |
In methods and an optical recording apparatus using these methods, an optimum write power of a radiation beam in the apparatus is set by writing a series of test patterns on the optical recording medium, forming a read signal from the patterns and processing the read signal. Such processing involves fitting a function, preferably a straight line, to parameters obtained from the read signal without having to perform a differentiation step. |
