Problems solved by technology

[0006] As mentioned above, whenever a file is recorded, according to the conventional data recording method, the DVD-RAM drive device 200 always recovers the data of a final part of the last recorded file on the DVD-RAM 300, and is related to the data to be recorded. The data of a file together generate a data block, thus resulting in an increase in data recording time

Embodiment Construction

[0016] combine now image 3 Describe in detail a preferred embodiment of the present invention, image 3 is a diagram for explaining a method for recording data in a DVD-RAM according to a preferred embodiment of the present invention. The method for recording data in a DVD-RAM according to the present invention performs ECC encoding on data of a file to be recorded in units of data blocks. When the size of a file to be recorded is not an integral multiple of a data block, dummy data is added to form a final data block, and ECC encoding is performed on the final data block. Then, each ECC block of the ECC-encoded data block is modulated to generate a physical sector. When the structure of a data block used in the present invention is the same as that used in the current method, and one ECC block corresponds to the physical data block 400 or 500 including 16 physical sectors. The present invention records the data of the file that will be recorded as a unit of physical data ...

Abstract

A data recording method error-correction-code (ECC)-encodes and modulates data of a file to be recorded in units of data blocks, and records the encoded and modulated data on a digital versatile disk-random access memory (DVD-RAM). Dummy data is added to make a last data block when the size of a file to be recorded is not an integer multiple of a data block, and then the last data block is ECC-encoded and modulated for recording the same on a DVD-RAM. The recording of data is performed in a recording region of a DVD-RAM where no data is recorded, and also starts from a recording region just next to the last data even when the last data of the previously recorded file includes dummy data.

Description

technical field [0001] The present invention relates to a method for recording data on a digital versatile disc (DVD), and more particularly to a high-speed data recording method for a digital versatile disc random access memory (DVD-RAM). Background technique [0002] A newer form of DVD is DVD-RAM in which data can be freely recorded and deleted. Since the DVD-RAM has a recording capacity for recording a large amount of data, it requires a high-speed data recording time. [0003] figure 1 A structure of a data sector for recording data in a DVD-RAM is shown. The data sector has a size of 2064 bytes, and the sector is composed of 12 rows, each row having 172 bytes. Each row in the data sector includes main data recording information. The beginning of the first row of the data sector includes identification (ID), identification error correction code (IEC), and reserved (RSV) data, and the ending part in the 12th row of the last row includes 4 bytes error detection code ...
