Embodiment Construction

[0044] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0045] Figure 2A and 2B is a block diagram of a recording apparatus according to a preferred embodiment of the present invention. see Figure 2A A recording device for forming marks or spaces on an optical recording medium 200 to record data includes a pickup unit 1 , a recording waveform generator 2 and a channel modulator 3 .

[0046] The channel modulator 3 modulates the input data into a sequence of channel bits. The recording waveform generator 2 is supplied with respect to the channel bit sequence and the cancellation power P b1 and P b2 information, and generate recording waveforms for recording channel bit sequences. The resulting recorded waveform includes an erased pattern with erased multipulses. The recording waveform will be described in detail later. The pickup unit 1 irradiates light to the optical recording medium 200 accordi...

Abstract

The invention provides a device for recording data on an optical recording medium. The device for recording data on an optical recording medium comprises a recorded-wave shape generator for generating a recorded wave shape which has a multi-pulse canceling mode, and a pick-up unit for implementing the light irradiation on an optical recording medium according to the generated recorded wave shape so as to form a label or an isolation, thereby preventing the labeled shape from deforming and improving the shape of the label, and further improving the recording and playing properties.

Description

[0001] This case is a divisional application of an invention patent application with an application date of December 16, 2002, an application number of 02156100.1, and an invention title of "Method and Device for Recording Data on an Optical Recording Medium". technical field [0002] The present invention relates to a method and apparatus for recording data on an optical recording medium, in particular to a method and apparatus for recording digital data by forming marks on an optical disc. Background technique [0003] When recording data on an optical recording medium such as an optical disc, marks are formed in tracks formed in the optical disc. A mark is formed as a pit of a read-only disc such as CD-ROM, DVD-ROM or the like. Marks are formed on recordable discs such as CD-R / RW, DVD-R / RW / RAM, etc., when a phase change occurs in a phase change layer that is changed to crystalline or non-crystalline depending on temperature. Crystallized and covering the recording layer....
