ABSTRACT:
A method and apparatus for implicitly partitioning the storage space available on a storage medium, to a storage medium for storing user data and to a recording device for storing user data on a storage medium. In order to limit the mount/unmount time of a volume like a UDF volume on a magnetic tape for ADR and to limit overall seek times during reading:a) storage space available for storage on the medium is divided into a directory region and a data region,b) metadata are stored in the directory region,c) user data are stored in the data region being implicitly subdivided into data sub-regions,d) file set data for user data stored in a data sub-region are stored in a corresponding directory sub-region being assigned to this data sub-region, ande) borders and size of data sub-regions are variable.
