METHOD AND RECORDING DEVICE FOR RECORDING SIGNALS ON A RECORD CARRIER |
摘要 |
<p>Disclosure is given of a device and method for recording by means of a radiation beam user information on a record carrier. The user information is written in the form of optically detectable marks in concentric tracks. The tracks are subdivided into sectors. The record carrier used has ring-shaped zones. Within these zones lie the sectors aligned seen in radial direction. For writing the marks in the tracks, a write intensity of the radiation beam is set to a determined set value. For this purpose, a test information pattern is written in a buffer sector which is situated on an edge of a zone. Then the test information pattern is read back during which operation the test information pattern is converted to a corresponding test data pattern. Based upon the test data pattern a set value for the write intensity is determined.</p> |
