Abstract

A recording medium read / write method and apparatus are disclosed. The present invention records version information of a corresponding recording medium as read / write control information within the recording medium. The version information includes write compatibility version information and read compatibility version information. The read / write apparatus efficiently performs the read / write of the recording medium with reference to the version informations recorded within the recording medium.

Description

technical field [0001] The present invention relates to a recording medium and its control information recording method, and more particularly to a method of recording read / write control information associated with a version of a corresponding recording medium as control information and a recording medium read / write method using the recorded control information and equipment. Background technique [0002] In general, optical discs on which a large amount of data can be recorded are widely used as optical recording media. Recently, many efforts have been made to develop a new high-density optical recording medium (HD-DVD) such as Blu-ray Disc (hereinafter abbreviated as BD), on which high-definition video data and high-quality audio data can be recorded and stored. [0003] Blu-ray Disc (BD), which is one of next-generation HD-DVD technologies, is a next-generation optical recording scheme capable of storing data significantly exceeding the storage capacity of conventional D...
