Problems solved by technology

However, as the recording density of data increases, a tolerance of less than one bit is difficult to achieve and is therefore unrealistic

example 4

[0303] FIG. 32 shows a top view of a recordable optical disc medium 701 according to a fourth example of the present invention. On the recording surface of the optical disc medium 701, recording tracks 702 are formed in a spiral manner. The recording track 702 is divided into a number of data blocks 703 . In other words, on the recording surface of the optical disc medium 701, the data blocks 703 are continuously arranged in the circumferential direction to form the information track 702.

[0304] FIG. 33 shows the data format of a data block 703 of an optical disc medium 701 according to a fourth example of the present invention. As shown in FIG. 33 , a first frame area 801 is located at the beginning of each data block 703 , and a plurality of second frame areas 802 are located after the first frame area 801 . The first frame area 801 and the plurality of second frame areas 802 form a data block 703 . In FIG. 33, an area shown on the right follows the area shown on the le...

Abstract

A recording medium comprising a recording area, the recording area includes a first area and a second area, the first area includes a frame area, the frame area includes an area in which a second synchronization code sequence and at least a portion of data are to be recorded, and the second area includes an area in which a third synchronization code sequence and a fourth synchronization code sequence are to be recorded.

Description

[0001] This application is a divisional application with a filing date of December 36, 2001, an application number of 01821385.5, and a title of "recording medium, recording method, reproducing method, recording device and reproducing device". technical field [0002] The present invention relates to an optical disc medium allowing high-density data recording and a method and apparatus for recording data on or reproducing data from the optical disc medium. Background technique [0003] Recently, the recording density of optical disc media has rapidly increased. In the case of an optical disc medium that allows digital data recording, data recording, reproduction, and management are generally performed in units of blocks each having a prescribed byte length. (Such a block is called a "data block".) Each data block is given address information. Data recording and reproduction are performed with reference to address information. [0004] For recording data on an optical disc ...
