Problems solved by technology

However, if only the radius of the laser beam is reduced, the amount of light used when recording / reading data is also reduced, and the effect caused by damage or dust occurring on the surface of the disc is relatively increased.
That is, the error generation rate increases when recording / reading data

Embodiment Construction

[0032] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0033] Figure 1A and 1B is a block diagram of a data recording apparatus according to a preferred embodiment of the present invention. refer to Figure 1A and 1B, the data recording apparatus includes an error correction code (ECC) encoding section 1 , a modulating section 3 and a recording section 5 . The ECC encoding section 1 includes an ECC encoder 11 and an interleaver 12 . The ECC encoder 11 encodes main data with an error correction code (ECC). The interleaver 12 interleaves the ECC-encoded main data according to the present invention to generate recording blocks. Interleaving is performed to increase error correction efficiency, and interleaving is a method for physically dispersing and recording adjacent main data on an optical disc in ECC blocks. By interleaving, burst errors can be corrected very efficiently. A more spe...

Abstract

Provided are an optical information recording medium, a data recording device, and a data recording method used by the device. Optical information recording medium containing data included in one or more recording blocks. Identifiers in a plurality of sectors including a plurality of error correction code (ECC) blocks are sequentially extracted so that the ECC blocks are equally selected and arranged at predetermined intervals. As a result, the provided optical information recording medium, data recording device and data recording method used by the device have a higher error correction rate.

Description

technical field [0001] The present invention relates to error correction, and more particularly, to an optical information recording medium, a data recording device, and a data recording method used by the device, which are capable of recording high-density data. Background technique [0002] Digital broadcasting will soon be common in many countries around the world. However, current digital versatile discs (DVDs) have a capacity of 4.7-10 Gbytes, so a two-hour movie (about 25 Gbytes) received via digital broadcasting cannot be recorded on one disc. As a result, a high-density recording medium for recording digital broadcasts having the capacity of one movie is required. [0003] A method of reducing the size of a laser beam used when recording / reading data is a representative example of a method of increasing recording density. The smaller the radius of the laser beam, the denser the information tracks in which data is recorded can be formed, ...
