This invention provides a method of managing the navigation data for a
rewritable recording medium which are referred to for control of
recording, editing, and reproduction. It enables to access to each
information table in the navigation data directly by referring to the
start address, which is kept in the first information table in the
navigation data. When data are recorded to the rewritable recording
medium, the management data which are relevant to the data to be recorded
are created and written to the relevant information tables, which are
accessed directly based on the start addresses. When data on the
recording medium are reproduced, the information tables which contain
management data required for reproduction of the requested data are
located directly by the start addresses. Then, the data are read out from
the rewritable recording medium and reproduced in reference to the
management data. Compared to the prior navigation data structure, where
the information tables are accessed through calculation of the end
addresses, the present invention allows to reduce the access time to each
information table, contributing to the real-time operation for writing
and reproduction.
