ABSTRACT:
The invention relates to an apparatus for recording a main file comprising a main information signal and auxiliary files comprising auxiliary signals in a track on a record carrier. The apparatus writes in a first location a block of an auxiliary file comprising a part of an auxiliary information signal having a specific presentation time, in a second location a subsequent block of the corresponding auxiliary file and in at least one location between the first and second location at least one block of the main file comprising a part of the main information signal having a presentation time which corresponds to the presentation time of the auxiliary information signal to be written in the first location. In this way the respective files are interleaved written on the record carrier such that the jumping time between subsequent read actions is significantly reduced. This results in an increase of the effective read bit-rate of a playback device.
