RECORDING MEDIUM, METHOD AND APPARATUS FOR REPRODUCING DATA ON THE RECORDING MEDIUM, AND METHOD AND APPARATUS FOR RECORDING DATA ON THE RECORDING MEDIUM
First Claim
1. A recording medium on which data is recorded in units of clusters to be read by a recording and/or reproducing apparatus, wherein:
- each of the clusters comprises a plurality of address fields;
each of the address fields comprises 32-bit address unit number (AUN) address information; and
the AUN address information comprises;
a reserved area recorded in 4 bits;
layer information, recorded in 3 bits, used by the apparatus to determine a layer on which data corresponding to the AUN address information is recorded; and
location information, recorded in 25 bits, used by the apparatus to determine a location of the data corresponding to the AUN address information.

Abstract
A recording medium on which data is recorded in units of clusters, a method and apparatus for reproducing data on the recording medium, and a method and apparatus for recording data on the recording medium, wherein each of the clusters includes a plurality of address fields, each address field includes 32-bit address unit number (AUN) address information, and the AUN address information includes a reserved area recorded on 4 bits, layer information, recorded on 3 bits, indicating a layer on which data corresponding to the AUN address information is recorded, and location information, recorded on 25 bits, indicating a location of the data corresponding to the AUN address information. In the recording medium of the present invention, a space in which addresses are recorded is expanded, thereby securing an address area in which addresses of data can be recorded in a data structure.
