Abstract: 1. A device for scanning an information carrier (1), which information carrier carries identification information (10, 11) and user information (7, 8), the identification information (10, 11) being spread over the information carrier and the information including data (7, 13) and parities (8, 12), which device includes read means (42, 34) for reading the information present on the information carrier, the device including error correction means (45) for the correction of errors in the information, characterized in that the device further includes organization means (46) for the organization of the information in such a manner that both the identification information and the user information can be processed by the error correction means (45). 2. A device as claimed in Claim 1, characterized in that the organization means (46) further include addition means (46) for adding dummy bytes (9) of predetermined value to the identification information (10, 11). 3. A device as claimed in Claim 1, characterized in that the device further includes write means. 4. A device as claimed in Claim 1, characterized in that organization means (46) are further adapted to collect the identification information (10, 11) by reading the address information areas (5) of a predetermined number of tracks and subsequently organizing the address information about the information carrier (1), the tacks of which are of substantially paralle, wherein reading the address information areas (5) comprise the identification information on tracks. 5. A device as claimed in Claim 1, characterized in that the organization means (46) are adapted to add eight dummy bytes (9) of non-zero value to the identification information (10, 11), particularly the value FF in hexadecimal notation when the that the predetermined number of tracks is two, each track including eight address information areas (5), each address information area comprising 15 bytes of address information. 6. A method of manufacturing an information carrier (1), the method comprising the following steps: a. receiving identification information (10, 11), b. calculating parities (12) on the basis of the identification information (10, 11), c. adding the parities ( 12) to the identification information ( 10, 11 ), d. outputting the identification information ( 10, 11 ) and parities ( 12), e. providing the information carrier (1) with the identification information (10, 11) and parities (12), characterized in that the identification information (10, 11 ) is arranged so as to be spread over the information carrier (1). 7. A method of manufacturing an information carrier (1), the method comprising the following steps: a. receiving identification information (10, 11), b. receiving dummy bytes (9) of predetermined value, c. calculating parities (12) on the basis of the identification information (10, 11) and dummy bytes (9), d. adding the parities (12) to the identification information (10, 11), e. outputting the identification information (10, 11) and parities (12), f. providing the information carrier (1) with the identification information (10, 11) and parities (12), characterized in that the identification information (10, 11 ) is arranged so as to be spread over the information carrier (1). 8. A method as claimed in Claim 9, characterized in that the dummy bytes (9) have a non-zero value, particularly the value FF in hexadecimal notation. 9. An information carrier carrying identification information (10, 11), the identification information (10, 11) being arranged so as to be spread over the information carrier (1), characterized in that the identification information (10, 11) comprises parities (12) calculated on the basis of the identification information (10, 11, 13). 10. An information carrier as claimed in claim 9, characterized in that the identification information (10, 11) comprises permanent information (10, 11) and in that the user information (7, 8) comprises rewritable information (7, 8). 11. An information carrier as claimed in claim 9, characterized in that comprises address information (50) and disc information (51).
