Embodiment Construction

[0098] A digital information recording / reproducing system according to an embodiment of the present invention will be described below with reference to the drawings.

[0099] As a typical embodiment of the digital information recording / reproducing system according to the present invention, an apparatus for recording / reproducing moving pictures encoded by MPEG2 at a variable bit rate, such as a DVD digital video recorder, is known. (An example of such a DVD digital video recorder will be described in detail later).

[0100] figure 1 is a perspective view for explaining the structure of a recordable / readable optical disc 10 used in a DVD digital video recorder.

[0101] Such as figure 1 As shown in , this optical disc 10 has a structure obtained by attaching a pair of transparent substrates 14 each having a recording layer 17 using an adhesive layer 20 . Each substrate 14 may be formed of a 0.6 mm thick polycarbonate film, and the adhesive layer 20 may be formed of a very thi...

Abstract

An erase prohibition setting unit sets erase prohibition in accordance with an instruction. When the range is not set in units of cells of the current cell, the current cell is divided by a cell separator to set a sequence of advanced cells. A reconstruction part reconstructs management information for playing, back the advanced cells and current cell, and appends erase prohibition information to the management information for playing back the advanced cells that belong to the range.

Description

technical field [0001] The present invention relates to a digital information recording medium having a limited storage capacity and premised on variable bit rate recording. [0002] The invention also relates to the use of digital information recording / reproducing systems with limited storage capacity. [0003] Furthermore, the present invention relates to digital video recorders for recording and reproducing information such as digital moving pictures compressed by MPEG. Background technique [0004] In recent years, systems for reproducing recorded video data (moving images), audio data, and other optical disc contents have been developed, and for reproducing movie software titles, Karaoke data and so on became popular. [0005] The DVD (Digital Versatile Disc) standard using the MPEG2 (Moving Picture Experts Group) international standard and using an audio compression scheme such as AC-3 (Digital Audio Compression) has been proposed. The DVD standard includes read-only...
