Embodiment Construction

[0021] In the present embodiment, take music disc or VCD as example, because the data in music disc and VCD sheet lacks one layer of error correction ability compared with general data disc, when making CD drive grab these audio-visual track data It is more difficult and more error data are obtained. Fortunately, such small errors in audio-visual data are acceptable as long as the human ears or eyes do not hear popping or staccato sounds, or see mosaics or pauses in the picture. Of course, the error rate of zero is the best. However, on the other hand, when duplicating data, the optical disk drive has a relatively long period of time to read data correctly, and can perform slow-down reading.

[0022] image 3 It is a flow chart of an embodiment of the method for preventing data reading errors in the present invention. From initial state (step starts (START)), comprise inserting optical disc, and decide to read mode; First, judge whether CD-ROM drive reads data pattern and be...

Abstract

The method includes following steps. A data-reading mode is determined. When the data reading mode is a video / audio play back mode, the first reading program reads out data on the carrier. When the data reading mode is a copying mode, the second reading program reads out data on the carrier. Data read out are output.

Description

(1) Technical field [0001] The present invention relates to a method for preventing data reading error of an optical disc drive, in particular to a method for preventing data reading error of a music CD. (2) Background technology [0002] Facing the advent of the era of digital technology, with the increasing amount of data processed by computers and the growing demand for huge storage capacity, although hard disk equipment manufacturers continue to improve and introduce new ones with high requirements for quality, capacity, speed, and stability, computer users if If important data is not properly backed up or saved in time, a heavy price must be paid. Not only the built data is destroyed, but also face the difficulty of rebuilding which consumes manpower, time and money. In the face of this dilemma, the launch of products such as optical discs, optical disc drives, and burners will bring storage media into a new era. CD-ROM has large capacity, small size, light weight, ea...
