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...
