Abstract

The present invention provides a high-speed optical recorder, which generates a write signal according to the input RLL modulation waveform to control the write power of the optical pickup. The high-speed optical recorder includes a rough delay device, which will be based on a set of write schemes parameters to generate rough delay parameters and fine delay parameters, and delay the eight to fourteen modulated waveforms according to the rough delay parameters to generate the first delay signal; and a precision delay chain, which includes a plurality of delay units connected in series, each of which The delay unit delays the first delayed signal for a predetermined time, and the precise delay chain delays the first delayed signal according to the precise delay parameter to generate the writing signal.

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...
