Methods of determining the optimal erase and write power, and recording apparatus with devices for said methods |
| 摘要 |
<p>The application relates to methods and devices for determining the optimal erase (17) and write powers for erasing and writing information on an optical record carrier (85). These optimal powers are determined from two powers, Pmin (15) and Pmax (16), found at specific points, (22) and (24), in a curve (10) where the normalized reflected power (12) is plotted versus the test power (11).</p> |
