Problems solved by technology

[0015] Therefore, when the circumference of the area where the recording and / or reproducing unit block is recorded is smaller than the length of the recording and / or reproducing unit block, an overlapping area is generated, the error correction capability is significantly reduced, and thus the reliability of the data is reduced

Embodiment Construction

[0035] According to an aspect of the present invention, there is provided a recording and / or reproducing apparatus including: a signal processing unit that performs signal processing of a first address and a second address to distinguish a first address located in a data recordable area of ​​an information recording medium. an area and a second area located in the data recordable area, the second area uses a recording and / or reproducing unit block of a size different from that used in the first area, and the data recording on or reading data from the information recording medium; and a control unit that controls the signal processing unit for recording using the first address in the first area of ​​the information recording medium and the second address in the second area of ​​the information recording medium and / or reproduce data.

[0036]The signal processing unit may include: a dither signal processing unit including a first dither processing unit processing the first addre...

Abstract

A recording and / or reproducing apparatus including a signal processing unit that performs signal processing of a first and a second address to distinguish a first area disposed in a data recordable area of an information recording medium from a second area disposed in the data recordable area, the second area using a recording and / or reproducing unit block with a different size from that of a recording and / or reproducing unit block used in the first area, and records data on or reads data from the information recording medium; and a control unit that controls the signal processing unit for recording and / or reproducing data using the first address in the first area of the information recording medium and the second address in the second area.

Description

technical field [0001] The present invention relates to an information recording medium, and more particularly, to a recording and / or reproducing apparatus, a recording and / or reproducing method, and a disc manufacturing apparatus and method, and / or an information recording medium. Background technique [0002] Currently, the channel bit length (CBL) of a digital versatile disc (DVD) is 0.133um. As DVD data storage density increases, DVD track width and CBL decrease. As a result, the error correction capability is reduced. A drop in error correction capability caused by a CBL drop can be compensated for by increasing the size of a recording and / or reproducing block, for example, from 32KB to 64KB. Therefore, increasing the recording and / or reproducing block size to compensate for the decrease in error correction capability is the best method for detecting errors in 80mm or 120mm discs. However, as the physical size of recording media continues to d...
