Abstract

The method involves recording at least two different types of files with different formats on the same recording medium. All the audio data are recorded at the start of the disc and text data in a later part of the disc. The first recording session is entirely audio, using the 44100 Hz and 16 bit stereo standard which can be read by all standard audio CD players. The second recording session is effected from a virtual image of the text files and documents, organised in a hierarchy from a root file. A table of contents indicating the start and finish of each file is recorded at the start of the session. This session records a file that will serve in the last session to record the final state. In a third session the table of contents is transferred to a buffer memory for recording at the end of the third session.

Description

Vinvention conceme un procédé d'enregistrement d'informations numériques audio et textes ou documents sur une piste de support d'enregistrement de tçpe non-effacable lequel procédé permet d'enregistrer ces deux types de fichiers aux formats différents sur le même support d'enregistrement.  The invention relates to a method for recording digital audio information and texts or documents on a track of non-erasable type recording medium which method makes it possible to record these two types of files in different formats on the same recording medium. .

There are indeed compact hybrid discs such as CD-Roms .1lied Mode which contain on the same surface data of different scores and in particular audio data and text or document data.

Toutefois. le procédé utilisé pour l'enregistrement de tels supports exige que les données textes outocuments soien[ situées en début de piste et les données audio à la suite. A la lecteurs sur une platine CD Audio. les données textes et documents génèrent un craquement mettant en danger l'appareil de lecture et occupent une place inutilisable par ce ripe de lecteur. Toujours selon ce procédé. l'emplacement en début de piste des données textes et documents est nécessaire pour que les lecteurs de type
CD-Rom puissent les lire.However. the process used for the recording of such media requires that the text data documents be [located at the start of the track and the audio data afterwards. Readers on an Audio CD player. text and document data generate a crack that endangers the reading device and occupies a space that cannot be used by this reader. Always according to this process. the location at the start of the text and document data track is necessary so that type readers
CD-Rom can read them.

L'obier de la présente inventions est un procédé selon lequel les données audio lisibles par les appareils de lecture CD audio standards pourront être positionnées avant les enregistrements textes et documen[s lisibles par les lecteurs de CD-Rom disponible sur le marché. The object of the present invention is a process according to which the audio data readable by standard CD audio playback devices can be positioned before the text recordings and documents readable by CD-Rom players available on the market.

Ce procédé vise donc à rendre le support enregistrable. grâce au procédé d'enregistrement. totalement compatible avec les lecteurs de compact disques audio tels qu'ils existent aujourd'hui et cela dès la lecture de la première piste ou track et également compatible avec les lecteurs de disques compact de type CD-Rom ou CD-I selon le format des données textes et documents gravées sur le support d'enregistrement.This process therefore aims to make the medium recordable. through the registration process. fully compatible with compact audio disc players as they exist today, as soon as the first track or track is played, and also compatible with compact disc players such as CD-Rom or CD-I depending on the format of the text and document data engraved on the recording medium.
