Problems solved by technology

[0014] However, the F / E integrated circuit device 105 of the existing DVD optical recording system described above will add information such as sector information and sector number to the main data (Main data) transmitted from the B / E integrated circuit device 101. , and perform error correction code (ECC) and modulation processing, so not only the calculation is complicated, but also the system processing efficiency is very low
[0015] In addition, when a large amount of data is stored on the optical disk, the complexity of the work in the F / E integrated circuit device 105 will increase, and the efficiency will decrease again.

Abstract

This invention relates to one light recording control system, which comprises the following parts: B / E integration circuit device for main data memory and to convert outside data into digital signals; F / E integration circuit device to convert main data and generate channel information after testing the main data error; B / E interface device; memory to store the main data written fan information and added fan number and CPR-MAI sections in the B / E integration circuit device; leg control information to indicate memory; laser diode driver to store the channel data into disc generated by F / E integration circuit device.

Description

(1) Technical field [0001] The present invention relates to an optical recording control system, especially when DVD (Digital Versatile Disc) is stored, reducing the complex calculation amount of the beginning / end F / E (FRONT END) integrated circuit IC (Integrated Circuit) device, and can efficiently An optical recording control system for storing data on an optical disc. (2) Background technology [0002] An optical disc is a storage medium designed to store large amounts of information. CD (compact disk) and DVD (digital versatile disk) are widely used among these optical disks. Among them, CD-R (Recordable compact disk) and CD-RW (Read-Writable compact disk) are mainly used for CD. As we all know, DVD uses 660nm laser, and CD-RW uses 790nm laser to store and reproduce information. Therefore, an optical recording / pickup head compatible with DVD and CD-RW has two types of light sources emitting different wavelengths, and optical devices for receiving these two types of li...
