This apparatus is designed for processing information stored in a data carrier in which information can be stored in many layers (L0, L1, . . . ) Often said information is arranged in files and related sub-files. It is proposed to arrange the file and the related sub-file in the same vicinity so that a displacement from the main file to a related sub-file is quickly made and vice versa. Application: video streams, for example, which have a certain quality level. For example, the quality is good for usage on a small portable screen. If a user wants to display this stream on a (large) screen, the enhancement sub-files placed in other layers can be used, which provides additional quality to the base layer stream.
1- An apparatus for processing information stored in a data carrier in which information can be stored in places defined by a first position indication and by at least a second position indication, comprising:
2- An apparatus as claimed in claim 1, wherein the data carrier is a removable one.
3- An apparatus as claimed in claim 1 wherein the data carrier is an optical disc comprising at least two layers, the first position indication defining a location on the surface area of the disc and the second position indication defining the envisaged layer.
4- An apparatus as claimed in claim 1, wherein means are provided for managing a defect in a file on the basis of other, related files.
5- A data carrier suitable for use in an apparatus as claimed in claim 1, comprising data organized in files and related sub-files such that at least a part of a file and its related sub-file are close together.
6- A data carrier as claimed in claim 5, constituted by an optical disc having at least two layers, wherein the files with their related sub-files are on different layers in the same locations of the disc.
7- A data carrier as claimed in claim 6, wherein the files and related sub-files are placed close together in one or a plurality of layers.
8- A method of storing a file with a plurality of related sub-files, comprising the steps of:
9- An optical head suitable for an apparatus as claimed in claim 1.
