CD-R already formed is development most fast light 盘格式, it application already ultra- 出存储 data, in CD-AUDIO field/area in to application. 随 计算 machine outer development, 脱离计算 machine system 独立CD-R刻录 machine already upper 市, for CD-AUDIO进行录 made, made has obvious increase. use 银 代替金 is CD-R this type of 格式 广泛 application most 终奠定 基础. in, large amount production CD-R light ratio production light need complex, difficult more, make 如此CD-R也取 不凡 formed 绩. in, due to development new, Raw Materials, and using/adopting new technology, make CD-R production cost large large reduce. ratio 如: using/adopting 银代替金做反射层, make 此项费 use from $0.50 drop to $0.36. in addition, production cycle shrink short reduce production cost. in 90 year 代初期 production cycle is 12秒, in is 6.5秒. 随 人们 for 存储容 amount increase demand and light technology development 必然结果, can 够存储 more more data DVD-R格式也浮出 water 面. this type of currently in industry in use relatively is 广泛, main/primary used for made as and 演示. versus 信不久之 rear, it will comprehensive for generally use 户, in DVD-R amount already to standards requirements 4.7GB容 amount. CD-R and DVD-R格式 记录 principle is same, in types in can use has machine material, and CD-R一样DVD-R can 兼容DVD-ROM and DVD-VIDEO. 开始CD-R has 1X speed degree can force, process 不断进步, already can to 2X, 4X speed degree, to 1998 year already to 8X speed degree 记录. for can 记录介质 coating has types can technology, is SAN process （Samsung-Akzo Nobel）, is Korea and Netherlands AKZO-NOBEL development. this development is is cost and increase CD-R system function, but also SAN-CD-R can use DVD播放 machine 读出. in CD-R production in, is using/adopting 缓冲层, make 便宜 染 material and low metal aluminum use, this process 同样也 can use in DVD-R格式 production in. in SAN process in, has 一层进行部 separation metal 层（Partial mirror） thick degree is several nano, is ensure it uniform distribution, Akzo.Nobel already 批准 针 for this new process Nestal Subsystem(Nestal子 system) in processing can light production in application. and light 盘格式一样, can 记录格式 light 盘 injection molding parts molding process is simple process process, many factors effect/influence most quality. ratio 如: and electrical process in structure and process. new production parameters adjustment, metal distribution, Laquering and DVD-R in bonding and other specific requirements and other and other. testing equipment for can 记录介质而言, remove already has for BRIEF and DISHING outer, more add complex testing is 必需. Nestal using/adopting Digital-instrumeng Namoscope for CD-R, DVD-R and DVD-RAM and DVD-RW盘 预刻槽进行 testing. this type of device in analysis 预刻槽 structure 时, 无需预先进行染 material coating and metal coating coating 布. remove this testing methods outer, especially design cooling tube/pipe 也安装 to coating system in. use analysis process process stability property and demolding temperature degree effect/influence. 预刻槽 复 made in using/adopting ring control injection distribution 时, need to most 佳 复 made 效果, remove need filling process outer, stability ring cycle, especially is cooling time and formed film temperature degree is key/critical factors. is anti 止出现 surface defects （雾点）, need has very good demolding technology, control molding temperature degree and ring cycle balanced very important （随 循 ring cycle shrink short, molding temperature degree decrease low ）. shrink short ring cycle has 一 极限, it is 由Briefh and Dishing resistant property 决定. molding temperature degree scope/range is surface defects 决定 （雾点）. Nestal实验室 already according to 实验完 formed lower table/sheet, it is for coating / machine combined and 特殊PC盘基 as 出. versus 互关连 走 toward suitable for injection molding parts molding process machine / coating combined. pressure 模CD-R 预刻槽 deep 220nm, DVD-R 预刻槽 deep in 150nm-200nm between. process 联系考虑 process optimization, 首先必 must process process can property. its in very important is: for production cycle 改变（控 pressure and cooling time 改变）, will effect/influence to sheet/slice quality parameters. can property: 盘基槽 deep / pressure deep *100 for 应一定 盘 semi 径, can made for most good 预刻槽. 平均槽 deep can molding and machine this type of can force. Brief and Dishing循 ring cycle long, Brief and Dishing 效果越 good, Brief table/sheet value <+_50mm(di 倍传送, 说明书<+-100mm)Dishing table/sheet value <0.20（ semi 径偏移, 说明书<+-1.2） process again property Nestal selection “直接 injection process ”, make thick degree drop to most low. in 实验室 research in, can through amount light weight stability property process process again property. Nestal承认 it CD-R weight 偏差不 large 于0.5%. molding system anti can force use testing methods can make PC盘基 污染 drop to most low 程序. 一旦发生污染, material will can uniform coating or can most and bonding in 一起. key/critical several is: molding system positive as time and can property —— in CD-R made in, dry 扰都会污染洁净室, will bad system temperature degree balanced. 无污染紧密 molding mechanism —— in molding inner, especially requirements design anti anti structure. molding process 通风必 must use 洁净空 gas. as plant/unit use gripper(small 手柄), anti belt/tape molding 区. pressure machine pressure machine lifespan various conditions effect/influence. for has can 记录介质 格式而言, pressure machine versus 当昂贵. has many different methods is is can can long pressure machine lifespan. 今天, in Nestal子 system in, CD-R pressure machine lifespan is 100000圈. 另一 限 made pressure machine lifespan is 偏心距, 偏心距 most large can ultra- 70um, 但今天, production already will it to 平均40um left right. in most good pressure 模母盘 and electrical conditions lower, is make pressure machine has most long lifespan below/following is key/critical: molding mechanism adjustment and positive. molding toward 导. 特殊（ machine 械） pressure control design. 特殊处理 反射 surface. can heavy 写介质 for can heavy 写介质, usually selection machine material （ metal ） coating, can 记录介质 and can heavy 写介质 in molding upper main/primary difference in 于预刻槽 形状. CD-RW 预刻槽 deep large 约40nm, DVD-RW 预刻槽 deep in 50nm-90nm between, positive is this 一点, can 写格式 in molding process and can 记录格式 versus ratio, 显 不十 separation important. use CD-RW不 can full toward lower 兼容旧 has device, 包括Audio播放 machine, therefore in short inner, it main/primary is can 写介质 use in machine upper, 进行文 parts and 备份. DVD-RAM is has Cartrige（保护 box/case ） light 盘格式, Nestal也 positive plan 提出一 types system solution/scheme, use production Cartrige and Jenel boxes.DVD most standards also has formed. 如: DVD-RAM, DVD+RW, DVD-RW都 is strong/high has force competition for 手.
