Abstract

The invention provides a method for using optical storage device to write data into optical storage media, which includes following steps: providing EFM waveform to optical storage device, the EFM waveform includes a previous stripe surface, current pit area and the next stripe surface; according to the wavelength of the previous stripe surface, current pit area and the next stripe surface, selects a group of writing project parameter from many groups of parameter; according to the parameter, it generates writing time length waveform; and uses the waveform to drive the optical picker to write data into the optical storage media.

Description

technical field [0001] The invention provides a high-speed optical recording apparatus (High Speed ​​Optical Recording Apparatus), in particular to a high-speed optical recording apparatus including a counter and a delay chain (Delay Chain). Background technique [0002] In recent years, with the increasing computing power of computers and the continuous improvement of network technology, users use computers as multimedia audio-visual media and use computers as the starting point for communicating with the virtual network world. Mass access to various information has become a trend. In this trend, due to the huge increase in demand for data storage, various storage tools have also become popular products. Among them, products that use optical discs as storage media, due to the low unit price of optical discs under the same storage capacity and It is light and thin, does not take up space, and is easy to carry. It has always attracted people's attention. Especially in recent...
