Abstract

A recording medium, and a method and apparatus for recording data in the recording medium are disclosed. The recording medium including an inner area, a data area, and an outer area includes a first test area contained in the inner area, and a second test area contained in the outer area, wherein the first and second test areas are formed by a predetermined wobble modulation method equal to that of the data area. Therefore, the recording medium can be applied to a method for manufacturing a Blu-ray disc, and data can be effectively recorded / reproduced in / from the recording medium, such as theBlu-ray disc.

Description

technical field [0001] The present invention relates to a recording medium, and more particularly to a physical structure efficiently used when recording data in the recording medium, and a method and apparatus for recording data in the recording medium using the physical structure. Background technique [0002] In general, an optical disc is widely used as a recording medium in which a large amount of data can be recorded. In particular, high-density optical recording media such as Blu-ray Discs (BD) capable of recording / storing high-quality video data and high-quality audio data for a long period of time have recently been developed. [0003] The BD based on the next-generation recording medium technology has been regarded as a next-generation optical recording scheme capable of storing data far exceeding the data volume of a conventional DVD. Recently, many developers have conducted intensive research on international standard technical specifications associated with BDs...
