Record Carrier and apparatus for exploring the record Carrier

摘要

1.Record Carrier comprising a servo Track (4) indicating an information Track (9) proposed to tax information blocks represented by Brands, such servo Track (4) has a periodic variation of a physical parameter at a Predetermined Frequency and parts Modul Adas to encode position information at regular intervals, a First type of Modulated Parts,With an initial element of bit synchronization and are of a Data type that have an element of data bits and a Second type of Modulated parts with an initial element of bit synchronization and Synchronization are of a type that have an element of synchronization Word Word,The Word Sync Element and the element of data bits are Modulated according to a same Predetermined type of modulation of the periodic variation, characterized in that the effective force of the element and the element synchronization Word data bits are equal,The effective force is the number of periodic Variations that are substantially different and available for Detection of the corresponding element. 2. - bearer of registration as claimed in claim 1, wherein the Synchronizer Component modular partial Word comprise two elements separated by an interval of periodic variations in unmodulated.
