Problems solved by technology

Even if the burner is set to the highest burning ratio at the factory, the recording quality of the disc is the best. However, due to the recording quality of the disc and the ambient temperature of the burner, the quality of the disc and the It is related to the aging condition of the computer. In fact, the burning quality of the same disc using various burning speeds is often unpredictable.
Therefore, the user cannot know in advance which burning speed can produce the best burning quality
Even the user may use an inappropriate programming speed to cause the problem of programming failure

Embodiment Construction

[0021] Please refer to FIG. 1 , which shows a structural block diagram of a burner according to a preferred embodiment of the present invention. The recorder 100 is, for example, a recorder equipped in a computer or a TV program recording device, and includes a disc tray 110 , a spindle motor 120 , an optical pickup head 130 and a processor 140 . The disc tray 110 is used for placing an optical disc 111 , such as a CD disc, a DVD disc or a Blu-ray disc. The spindle motor 120 is controlled by the processor 140 to rotate the optical disk 111 corresponding to a recording speed. The optical pickup head 130 is used to burn the optical disc 111 according to the control of the processor 140 . In addition, the processor 140 controls the spindle motor 120 to make the optical disc 111 rotate corresponding to a certain recording speed, and controls the optical pickup 130 to perform the OPC program to obtain the recording quality of the disc corresponding to the recording speed. The ind...

Abstract

Burning and recording device includes optical picking up head, and processor, providing multiple operation speeds. The optical picking up head is in use for burning and recording optical disk. Based on each burning and recording speed, processor controls the optical picking up head to execute optimal power correction (OPC) program and provides burning and recording qualitative index based on the program. The method for selecting final burning and recording qualitative index includes following steps: placing optical disk sheet into the device, based on each burning and recording speed, the device executes OPC program to obtain corresponding burning and recording qualitative index; based on burning and recording qualitative indexes, selecting a final speed from burning and recording speeds supported, and the device carries out burning and recording operation for optical disk sheet based on the selected final speed.

Description

technical field [0001] The present invention relates to a method for selecting the final recording speed (Recording Speed) and its recorder (Recorder), and in particular to a method for selecting the final recording speed that can select the best recording speed according to the disc recording quality and its recorder. Background technique [0002] The burner usually has multiple supported burning speeds for burning optical discs, such as CDs or DVDs. As far as 16 times DVD discs are concerned, the supported burning speeds are 1 times, 2 times, 4 times, 8 times, 12 times and 16 times. The burning quality of the disc is related to the burning strategy used by the burner. [0003] The programming strategy includes the setting of laser programming waveform and laser programming power. Laser burning waveforms corresponding to various burning speeds are usually preset in the burner or CD. When the burner starts to burn an optical disc at a certain burning speed, it will first...
