Abstract

The present invention provides a method and an apparatus for encoding / decoding data, and a method and apparatus for recording / reproducing data. A method and apparatus for stably encoding / decoding data, and a method and apparatus for recording / reproducing data are disclosed. The method inserts decoding information into a data section including several predetermined-bit data, determines encoding values of the data according to a transition state of the data and a value of corresponding data, and generates the decoding information and the determined encoding values in units of the data section.

Description

technical field [0001] The present invention relates to a method and apparatus for recording / reproducing data, and more particularly, to a method and apparatus for encoding / decoding data, and a method and apparatus for recording / reproducing data using the encoding / decoding method. Background technique [0002] An apparatus for recording / reproducing information or data in / from a recording medium (for example, a compact disc (CD) or a digital video disc (DVD)) can record information or data on a single-layer recording surface, and can reproduce information on the single-layer Record Information or data recorded in a surface. [0003] If the recording / reproducing surface of the recording medium described above is constructed in the form of a laminated structure, the storage capacity of the recording medium can be greatly increased. However, the number of recording / reproducing surfaces that can be laminated on a single recording medium is generally set to a maximum value of 4, ...
