Embodiment Construction

[0127] Best Mode for Carrying Out the Invention

[0128] An information recording medium according to the present invention includes a chain volume management information area provided in the lead-in area and each overflow protection area. In each chain volume management information, the address information of the subsequent logical section and the address information of the chain volume management information area are recorded.

[0129] Further, according to the present invention, an information reproducing apparatus using such an information recording medium accesses the linked lead-in area and subsequent overflow protection area until an unrecorded area or the chain volume management information recording disk end information is detected, and the latest chain volume is read out. management information, and obtains the physical address of the end of the accessible area from the address information of the previous logical sector. In such an access operation o...

Abstract

An information recording medium comprises a data recording area. A lead-in area and a volume space are allocated in the data recording area in advance. The volume space is constructed so as to allow a logical zone for recording at least a volume-file structure and an over-run protection area for preventing an access to an unrecorded area to be alternately allocated in the volume space. The lead-in area and the over-run protection area each include a chain volume management information area for storing chain volume management information. The chain volume management information includes address information of a subsequent logical zone and address information of a subsequent chain volume management information area.

Description

[0001] This invention is a divisional case of the Chinese invention patent application with the filing date of May 30, 2001, the application number of 01812732.0, and the title of the invention as "information recording medium, information recording method, information recording device, information reproduction method and information reproduction device" Apply. technical field [0002] The present invention relates to an information recording medium, and a method and apparatus for recording information into the medium. The present invention also relates to a method and apparatus for reproducing information recorded in an information recording medium. More particularly, the present invention relates to an information recording medium in which there is a lead-in area and an over-run protection area, both of which include a chain for recording an end position for acquiring an accessible area. (chain) volume (volume) is an area for managing information, and it...
