Problems solved by technology

In particular, in practice, different recording waveforms should be used for each type of optical disc, which means that there will be problems in manufacturing multi-drives that can record / reproduce optical discs of all specifications, because multi-drives must be adapted to various different recording waveforms
This problem causes an increase in the cost

Embodiment Construction

[0039] figure 2 is a block diagram of a recording apparatus according to a preferred embodiment of the present invention. refer to figure 2 A recording device capable of forming marks on an optical recording medium 200 has a pickup unit 1 , a recording waveform generation unit 2 and a channel (channel) modulation unit 3 .

[0040] The channel modulation unit 3 modulates data input from the outside into a channel bit stream. The recording waveform generation unit 2 receives a channel bit stream and generates a recording waveform for recording the received channel bit stream. The recording waveform generated according to the present invention has an erase pattern which contains erase multi-pulses. Waveforms will be explained later. The pickup unit 1 irradiates light on the optical recording medium 1 according to the generated recording waveform so as to form marks or spaces.

Abstract

A method and apparatus for recording data on an optical recording medium are provided. The method forms a mark or a space by using a recording waveform having an erase pattern containing a multi-pulse. By doing so, the method prevents distortion of and improves a mark shape such that the characteristic of recording / reproducing is improved.

Description

[0001] This application is a divisional application of the application number 02144455.2 titled "Method and Device for Recording Data on Optical Recording Medium" filed with the China Intellectual Property Office on September 28, 2002. technical field [0002] The present invention relates to a method and apparatus for recording data on an optical recording medium, and more particularly to a method and apparatus in which data is recorded on an optical disc by forming marks on the optical disc. Background technique [0003] Recording data on an optical disc as an optical recording medium means forming marks on tracks formed on the optical disc. On a read-only optical disk such as a compact disk read-only memory (CD-ROM) and a digital versatile disk read-only memory (DVD-ROM), marks are formed as pits. In recordable optical discs such as CD-R / RW and DVD-R / RW / RAM, a phase-change (phase-change) film is formed in the recording layer, which can be changed into a crystalline phase ...
