RECORD CARRIER AND APPARATUS FOR SCANNING THE RECORD CARRIER. |
摘要 |
<p>A record carrier (1) is described which has a servo track (4) indicating an information track (9) intended for recording information blocks represented by marks. The servo track (4) has a periodic variation of a physical parameter at a predetermined frequency and modulated parts for encoding position information at regular intervals. The modulated parts start with a bit sync element and are of a data type having a data bit element or of a word sync type having a word sync element. The bit sync element and the data bit element are modulated according to a same predetermined type of modulation of the periodic variation. The modulated parts further comprise modulated parts (40,41) of an isolated bit sync type only having the bit sync element. Further a device for reading and/or writing the record carrier is described.</p> |
