ABSTRACT:
A recording/reproducing method which is capable of responding to the recording of various applications by flexibly changing the format of recording regions on a track of a recording medium. A track 20 is divided into a plurality of recording regions 22-32, and the data format of each recording region is selected in accordance with applications to be recorded. The preamble (or IBG) E.sub.PI is provided at the head portion of a track and the recording region to be independently rewritten or reloaded as occasion demands. A format information D.sub.PI indicating the presence of preamble or IBG is recorded in the data region E.sub.D. By designating required number of recording regions using the preamble (or IBG) E.sub.PI, it becomes possible to flexibly respond to the recording of various applications.
