Abstract

Verfahren zum Verkürzen der Zeit bis zur Aufnahme und/oder Wiedergabe von digitalen Daten auf einem plattenförmigen Datenträger, der einen festen Datensatz (Table of contents-TOC) und einen veränderlichen Datensatz (User Table of Contents (UTOC)) enthält, dadurch gekennzeichnet, daß durch Betätigen mindestens einer Taste unmittelbar nach dem Lesen des festen Datensatzes mit der Aufnahme oder Wiedergabe der digitalen Daten zum Verkürzen der Zeit bis zur Aufnahme oder Wiedergabe begonnen wird.Method for shortening the time until the recording and / or reproduction of digital data on a disk-shaped data carrier which contains a fixed data record (Table of contents-TOC) and a variable data record (User Table of Contents (UTOC)), characterized in that by pressing at least one key immediately after reading the fixed data record, the recording or playback of the digital data is started to shorten the time until the recording or playback.

Description

Datenträger zur Aufnahme von digitalen Daten, beispielsweise eine MO-Disk (Magneto-Optische Disk), sind in ihrer Organisationsstruktur regelmäßig so aufgebaut, daß sie zum einen einen festen Datensatz (Table Of Content-TOC) oder feste Directory enthalten, der beispielsweise notwendige Steuerdaten für einen Recorder enthält. Zum anderen ist üblicherweise neben den eigentlichen Aufnahmedaten ein veränderlicher Datensatz vorgesehen, eine sogenannte User (Benutzer)-Directory oder UTOC (User Table Of Contents), die Daten, beispielsweise (Sprung-)Adressdaten der bereits gemachten Audio-Aufzeichnungen, enthält.Data carriers for recording digital Data, for example an MO disk (Magneto-Optical Disk) In its organizational structure, it is regularly structured in such a way that it a fixed record (Table Of Content-TOC) or fixed directory contain, for example, the necessary tax data for one Includes recorder. The other is usual in addition to the actual recording data, a changeable data record is provided, a so-called user directory or UTOC (user table Of Contents), the data, for example (jump) address data of the already made audio recordings.

Um eine Aufnahme durchzuführen, wird bisher nach dem Einlegen eines Datenträgers wie z.B. einer MO-Disk in einen Recorder zunächst die TOC und anschließend die UTOC gelesen, bevor eine Wiedergabe öder eine weitere Aufnahme erfolgen kann.To take a picture, Previously after inserting a data medium such as a MO disk into a recorder first the TOC and then read the UTOC before playback or further recording can take place.

Das Lesen der TOC muß unbedingt erfolgen, da sie wie oben erwähnt notwendige Steuerdaten für den Recorder bzw. für den Datenträger enthält. Sind auf dem Datenträger bereits Aufnahmen abgelegt, kann das Lesen der UTOC bei diesem Datenträger unter Umständen jedoch recht lange, unter ungünstigen Umstän den mehrere Sekunden, dauern. Vom Einlegen einer Disk bis zur möglichen neuen Aufnahme oder Wiedergabe kann unter ungünstigen Umständen also eine lange Zeit verstreichen.Reading the TOC is imperative be done as mentioned above necessary tax data for the Recorder or for the disk contains. Are on the disk Already stored recordings, reading the UTOC can be found on this data carrier circumstances however, quite a long time, under unfavorable Circumstances several seconds. From inserting a disc to the possible one new recording or playback can therefore under unfavorable circumstances to pass a long time.

Es sind bereits ein digitales Tonbandgerät und ein Verfahren für dessen Betrieb bekannt, bei welchem der Zustand eines Löschsperretabulators festgestellt und eine TOC-Information vom Band nur übertragen wird, wenn der Löschsperretabulator einen nicht aufzeichnungsfähigen Zustand anzeigt, vgl. DE 39 17 009 A1 und es ist weiterhin eine optische Speicherplatte bekannt, bei der in einem nicht überschreibbaren Bereich ein Höchstwert für die Anzahl von Aufzeichnungen oder für die Gesamt-Aufzeichnungsdauer gespeichert ist, vgl. DE 39 31 206 A1 .A digital tape recorder and a method for its operation are already known, in which the state of a deletion inhibit tabulator is ascertained and TOC information is only transmitted from the tape if the deletion inhibitor tabulator indicates a non-recordable state, cf. DE 39 17 009 A1 and an optical disk is also known in which a maximum value for the number of recordings or for the total recording time is stored in a non-rewritable area, cf. DE 39 31 206 A1 ,

Aufgabe der Erfindung ist es, die Zeit vom Einlegen eine Datenträgers, wie z.B. einer MO-Disk, bis zu einer möglichen neuen Aufnahme oder Wiedergabe zu verkürzen.The object of the invention is that Time from inserting a disk, such as. a MO disk until a possible new recording or Shorten playback.

Gemäß der Erfindung wird die Aufgabe bei einem Verfahren gemäß dem Oberbegriff des Patentanspruchs 1 dadurch gelöst, daß unmittelbar nach dem Lesen des festen Datensatzes mit der Aufnahme oder Wiedergabe von Daten begonnen wird.According to the invention the object in a method according to the preamble of claim 1 solved in that immediately after reading the fixed record with the recording or playback of data is started.

Die Aufgabe wird zudem mit einer Anordnung gemäß Anspruch 3 gelöst. Vorteilhafte Ausgestalungen der Erfindung sind in den Unteransprüchen angegeben.The task also comes with a Arrangement according to claim 3 solved. Advantageous embodiments of the invention are specified in the subclaims.

Die UTOC wird in diesem Falle nicht gelesen, sondern unmittelbar nach dem Lesen der TOC wird mit einer Aufnahme oder Wiedergabe begonnen.In this case, the UTOC will not read, but immediately after reading the TOC is with a Recording or playback started.

Zwar kann es bei einem solchen Aufnahmeverfahren passieren, das vorherige Aufnahmen auf dem Datenträger gelöscht oder überschrieben werden, gerade dies jedoch ist unter Umständen auch beabsichtigt, wenn der Benutzer z.B. eine irgendwie teilweise bespielte MO-Disk, deren Aufnahme nicht weiter verwand werden soll, nicht extra löscht, sondern einlegt und sofort mit der Aufnahme beginnen möchte.It can happen with such an admission procedure happen that previous recordings on the disk deleted or overwritten , but this may be the intention, if the user e.g. a somehow partially recorded MO disk, whose Recording should no longer be used, not deleted, but instead inserted and wants to start recording immediately.

Dazu ist es vorteilhalft, wenn ein Aufnahmegerät für die Datenträger wie z.B. ein MOD-Recorder eine sogenannte "Quick-Record/(Play)-Taste" aufweist, die eine Durchführung des Aufnahmeverfahrens gemäß dem Anspruch 1 ermöglicht.It is advantageous if a recording apparatus for the disk such as. a MOD recorder has a so-called "quick-record / (play) button" which carries out the Admission procedure according to the claim 1 enables.

Mit dem Drücken der Quick-Record-Taste, wird der oben beschriebene Quick-Recard(oder Play)-Mode (Q-R-Mode) eingeleitet, der die Aufnahme gemäß dem Patentanspruch 1 durchführt. Vorzugsweise ist die Quick-Record (Play)-Taste mit der normalen Record (Play)-Taste gekoppelt. By pressing the quick record button, the quick recard (or play) mode (Q-R mode) described above was initiated, the inclusion according to the claim 1 carries out. Preferably, the Quick Record (Play) button is the normal one Record (Play) button paired.

Ein besonderer Vorteil eines solchen Aufnahmeverfahrens ist es, daß die Zeit vom Einlegen einer MOD bis zum Beginn einer Aufnahme oder Wiedergabe erheblich verkürzt wird.A particular advantage of one It is the admission procedure that the Time from inserting a MOD to starting recording or playback significantly shortened becomes.
