1. A method implemented in an apparatus for playback of multimedia data content from a removable optical disk for retrieving a file system of the removable optical disk, the file system indicating physical positions of content on the removable optical disk, the method comprising:
- upon insertion of the removable optical disk into the apparatus, determining a signature of the removable optical disk by measuring features based on a data pattern stored on the removable optical disk, the signature including a plurality of elements;
comparing the signature with a plurality of signatures stored in a content database; and
retrieving the associated file system indicating the physical position of the content on the removable optical disk from the content database if the signature is equal to a signature stored in the content database.
