US 7,257,226 B1 · Information management method and information management apparatus

Abstract

An information management method and an information management apparatus can minimize the confusion and the degradation of signal quality that can arise in terms of the compatibility of an apparatus adapted to a set of new standards and another apparatus adapted to a set of old standards. The protection flag of track mode is made equal to 1 as protection information for protecting the recording area of a disk carrying strings of codes according to the new standards from recording, editing and erasing operations of an apparatus conforming to the old standards and adapted to be able to refer only the management data area of the disk. When the disk carrying strings of codes recorded according to the new standards is used by the apparatus conforming to the old standards, the recording area of the disk is protected from recording, editing and erasing operations of the apparatus conforming to the old standards as the protection flag is 1.

Dependent claims

An information management method comprising:

generating protection information for protecting the storage area of a recording medium storing a second string of codes recorded by a second audio coding technique from any recording, editing and erasing operations of a first apparatus adapted to handle a first string of codes by a first audio coding technique and by referring to first management data stored in a first management data area;
arranging said protection information in the first management data area as one of said first management data;
and
protecting the storage area of the medium storing said second string of codes from any recording, editing and erasing operations of said first apparatus, while allowing reproducing operations of said first apparatus, on the basis of said protection information when the medium storing said second string of codes is operated by said first apparatus,
wherein said protection information includes a protection mode for a track on the medium, the protection mode indicating that the track is prohibited from rewriting.
