1引言光存储技术发展到今天,传统的可记录媒体CD-R 稳步增长,仍保持其固有的市场份额和应用领域,而代表了先进技术的DVD±R呈现出快速增长的势头。由于DVD-R较DVD+R进入市场早,是目前DVD可录盘的主流产品,但DVD+R以其自身的技术优势,大有赶超DVD-R之势。从北京市场上销售的DVD-R盘片中选取不同价位的9种品牌,及国内厂商提供的1种品牌,共 10种品牌(如表1所示),进行光学和电信号检测,其目的有二:调查盘片质量;为制订我国自己的DVD-R光盘测试规范提供参照。调查报告分为两部分:1)质量调查 2)测试结果分析。本期介绍第1部分。
1 Introduction Optical Storage Technology Today, CD-R, a traditional recordable medium, has been steadily growing while still retaining its inherent market share and application areas. DVD ± R, which represents advanced technology, shows a rapid growth momentum. Since DVD-R enters the market earlier than DVD + R, DVD-R is the mainstream DVD recordable product at present. However, DVD + R is superior to DVD-R in its own technical superiority. From the Beijing market, DVD-R disc selection of different price of 9 brands, and domestic manufacturers to provide a brand, a total of 10 brands (shown in Table 1) for optical and electrical signal detection purposes There are two: to investigate the quality of the disc; to provide reference for China’s own DVD-R disc test specifications. Survey report is divided into two parts: 1) quality survey 2) test results analysis. This issue introduces Part 1.
