The invention relates to a system for improved access control, in particular copy protec-tion, and improved personalized processing of information, the system comprising a record carrier ( 1 ) like a CD-RW+ or a DVD storing copy-protected information and a device for reading and/or writing the record carrier. For that, the record carrier ( 1 ) has a first area ( 3 ) for storing a first kind of information and further has multiple second areas ( 4.1, . . . , 4.8 ) each designed for comprising a storage medium for storing second kinds of information, these storage media preferably being implemented as chips. For copy protection, the first kind of information may be encrypted and the second kinds of information may contain decryption information. The use of multiple storage media for the second kinds of information provides for a more flexible design in distributing the storage and, preferably, computing resources over the record carrier ( 1 ). Furthermore, making the storage media detachable from the record carrier ( 1 ) results in an easy way of handling diversified access rights and personalization information.
