Audio information is stored on a unitary storage medium with a Table-of-Contents (TOC) mechanism for therein specifying an actual configuration of various audio items on the medium. In particular, one or more Sub-TOCs are each assigned to a respective different audio format. A single Master-TOC is provided for specifically pointing to each Sub-TOC.

Audio-centered information is stored on a unitary medium by using a Table-of-Contents (TOC) mechanism that specifies an actual configuration of various audio items on the medium. In particular, each one of a set of one or more Track Areas gets at least two mutually logically conforming Sub-TOCs assigned. This allows to retrieve any constituent Sub-TOC part from at least any correct copy of the Sub-TOCs. Furthermore, one or more Master-TOCs are provided for specifically pointing to each of the Sub-TOCs.

A device for recording blocks of information on logical addresses on a write once record carrier at corresponding physical addresses. The logical addresses are translated into the physical addresses by addressing means (). Allocation means () define a continuous addressing space for a user area and divide it into a front area, a middle area and a rear area for sequentially recording information by allocating to them parts of the user area address range. The device has re-allocation means () for splitting the middle area into new areas, specifically when no more data can be stored in the rear area or the front area.

Audio-centered information is stored on a unitary medium by a Table-of-Contents (TOC) mechanism for specifying an actual configuration of various audio items on the medium. In addition to the TOC mechanism a file-based access mechanism to the information is assigned through a ROOT directory that contains a highest level TOC directory pointing at various audio items.

A record carrier has at least two parallel substantially co-extending information layers that are suitable for scanning by a single scanning head. Each information layer has a control block for storing information for controlling the scanning of user information stored in the respective information layer. The control blocks are placed in the record carrier such that they can be sequentially read by a scanning device, with minimum displacement of a scanning head. The user information may be stored in a first format in the first information layer, and user information for the same contents may be stored in a second format in a second information layer. The first format may be a low-density structure and the second format may be a high-density structure.

For mapping sampled digital audio information onto a linear physical mapping space that is partitioned in a string of uniform-sized blocks, in particular, for variable-rate coded audio information that is distributed over successive audio units which are each composed from one or more audio packets, each block is supplemented with a block header for indicating an actual content of the block in question with respect to any constituent packet of the audio information.

Audio-centered information is stored on a unitary storage medium through a Table-of-Contents (TOC) mechanism that specifies an actual configuration of various audio items. In particular, in addition to the TOC mechanism a file-based access mechanism is assigned to the audio-centered information by a higher level Audio file. At a next-lower level a mechanism is assigned separately as one or more track-wise organized files indicating exclusively audio items contained in the area, and separately therefrom a comprehensive file indicating audio tracks as well as interposed pause intervals.

A record carrier provided with at least two parallel information layers suitable to be scanned by means of a single scanning head is described. Each information layer is provided with a control block in which information is stored which can be used for reading the user information stored in this information layer. The control blocks are placed in the record carrier in such a way that they can be sequentially read by means of a scanning device, with a minimum displacement of the scanning head. The user information may be stored in a first format in the first information layer, and the same user information may be stored in a second format in a second information layer. The first format may be a low-density structure and the second format may be a high-density structure.

A disc-like record carrier has a machine-readable information track in which is provided record carrier control information including the actual physical diameter of the carrier.
