Embodiment Construction

[0032] figure 1 In order to illustrate the structure of the data frame of the present invention, 12 rows (rows) contain 4-byte ID (identifier: identifier, hereinafter referred to as ID) and 2-byte IED, 6-byte MSF, and 160 (D0 -D159) bytes of main data; 172 bytes of main data (D160-D331); 172 bytes of main data (D332-D503)...172 bytes of main data (D1708-D1879); And the data frame formed by 168 (D1880-D2047) bytes of main data and 4 bytes of EDC in row 12 (rows).

[0033]In the present invention, as mentioned above, in the user data of 2048 bytes, use RS-PC ECC (the error correction code of the error correction coding method, hereinafter referred to as RS-PC ECC) and 8 / 16 modulation code (comprising Modulation code with a coding rate similar to it), to record data at a high density (twice the existing capacity) on the data frame of the CD-R / RW disc as a scheme, in the above figure 1 The data frame structure, change the ID and MSF part, the process is as follows:

Abstract

Under DVD data frame structure, let two physical sections (sector) correspond to 1ATTP frame structure of CD - R / RW. Number of sector is recorded in number of section of ID, and field type and data type etc. information is assigned to section information of ID. The data frame structure in the invention records minute, second of ATIP absolute time information and frame structure information onto 3bytes of 6 bytes MSFA part; or records conversion information of ATIP absolute time and the left 3 bytes as standby. The invention uses current CD - R / RW optical recording media, modifies ID and MSF sects properly, overcomes absolute time processing limit in current CD - R / RW media. Moreover, the invention guarantees high-density data recording and play back environment of CD - R / RW optical disk.

Description

[0001] technical field [0002] The invention relates to a method for high-density data recording of an optical recording medium. The present invention relates to the data frame structure and its recording method of recording data on optical recording media with high density, especially refers to recording user data on CD-R / RW (CD-R or CD-RW) with high density. ), the high-density data recording format of the optical recording medium that uses the DVD data frame structure to simplify high-density recording and playback. Background technique [0003] A CD-RW drive is a device that connects to a PC and reads or stores data from a CD-RW. This CD drive can generally read out serial data recorded on CD discs (CD-ROM, CD-AUDIO), and can also record data on optical discs (CD-R) (CD-RW). In particular, CD-R can only be recorded once, while CD-RW can be recorded multiple times. Since each data complies with the standard format of the CD series (the format defined by the Red Book, Ye...
