劣碟处理与抓轨的实践经验小结

概念阐述

劣碟

劣碟，顾名思义，就是自身状况不佳导致读取不顺、不准的碟片，包括但不限于：

制造时采用劣质材料的
长期放置导致材料老化的
存放不当导致反射面被刮花的
存放不当导致沾染了难以除去的胶水、纸屑等的

光驱

遇到的碟多了，光驱也收了不少，我所见过的光驱大致有以下几类：

平庸型

价格不高、抓轨表现毫无亮点的。

速度型

连 DVD 都无法读取的旧款 CD 光驱，抓碟速度一等一的快，读碟能力也很不错，如 BENQ - CDRW 52X32，速度可以飚到 12.6×，如：

精确型

抓轨精度极高，但身娇肉贵，动辄要纠错的，如位列 2019 年度 CD／DVD 光驱准确度榜单第一的 ASUS - BW-16D1HT，是一个蓝光光驱，但抓轨速度令人不敢恭维：

因此，鉴于其昂贵的价格（本体 318 + 外置盒 108）和「娇贵」的特性，我不是很推荐它。

强读取型

价格仅 100+，在榜单中也不见身影的 HL-DT-ST - DVDRW GS31N，在读取劣碟时，表现竟出乎意料地好，它似乎能够忽略掉那些细小的问题，同时把握住大局，抓得令人满意的结果。此外，由于是吸入式光驱，它很薄，且只需要一根 SATA 转 USB 线即可正常工作，便携且方便（前面两位为了工作稳定套了外置盒，需要电源线、数据线各一根，相较而言，这个已经方便很多了）。抓取速度较慢，能高于 1.0×，后期能跑上 2.0×，3.0×：

除此之外还有很多很多各式各样的光驱，甚至有非常老式的、我从未见过的摇臂式光驱。

摇臂式光驱

然而光驱之间的区别还有很多很多，如，有的光驱能读取黑色 CD 而有的不能；有的光驱能读取 HTOA（位于第一轨之前间隙中的隐藏音轨）而有的不能；有的具备踰读功能而有的不具备；我也见证了在光头寿终正寝以后抓轨速度飞快却无法读出任何有效数据的光驱……总之，我亲眼所见也只是沧海一粟，也欢迎大家分享自己光驱的一些特性。

如何处理劣碟

这是一个老生常谈的问题了，相信也困扰着为数不少的朋友，在博文中，有翻译自外国作者分享的划痕 CD 修复指南，其基本原理是打磨和抛光，我亲测过，是有效的，但其正常读取的有效性似乎有赖于残留的抛光剂，一旦彻底挥发，读取的情形似乎变得更糟，也许和光驱本身读取能力稍弱也有关联。

我忘记在哪里看过一个方法，工具是牙刷和牙膏，大家都知道牙膏内含研磨剂，我处理的专辑还记得很清楚，是 太阳部落 - 唱给未来的歌，因为包装劣质，直接与纸壳接触的 CD 反光面被胶水胶上了纸屑，直径大概 3 毫米左右，非常大的一坨，还有一些比较小块的，为此我还重新买过一张，两张都是一样的症状，无非程度有别，显然这个包装是非常劣质的。当时我采用的方法就是涂上牙膏，用牙刷把这些多余的东西刷掉，结果你们也能看到，是 100% 的抓轨。

但我心中始终有些惴惴：这样处理得来的「精确抓轨」，它是真正的精确吗？

在忘却了被音频怪物的《音为你》支配的恐惧后，我又一次遇到了一生之敌，它是 汐音社 - 人间词话。当然你们能看到本文就说明我顺利克服了这些困难，毕竟解决不了问题的方法我也不好意思拿出来说。专辑是 2015 年的，距离现在确实已经有了不短的时间间隔。第一张和第二张碟用 BENQ - CDRW 52X32 可以正常读到并抓取，然而后面三张它就无法识别，碟片放进去，吱吱响一阵就显示光驱内无 CD，所谓「巧妇难为无米之炊」，莫过于此，读都读不到，抓取效果又快又好又有什么用呢？只能另想办法。也正是为此，我购买了 ASUS - BW-16D1HT，完成了对第五张碟的抓取。到了第三张和第四张，它就犯了难了，为了至少不一无所获，我甚至用上了爆发模式：

惨烈的结果

惨烈的 Log，惨烈的抓轨

Log 惨烈，音频就更惨烈了，我不藏私，百度网盘，提取码：rr7n。我简单描述一下听感，如果你了解波形重建的原理，就会知道，原本正确的那些音乐内容你仍然能听到，但是会多一些奇奇怪怪的东西，在这里，是节奏固定的、快速的塑料片划过蒲团的声音，而且近在耳边。如果你不想下载整个有问题的抓轨，下面提供单个音轨的对比：百度网盘，提取码：yy9f。

破局之道

于是我就在想了，记录数据的凹凸层被盖在透光层的下面，除非是严重的破坏，否则一般是伤不到的，也就是说，CD 存储的数据是没问题，有问题的是透光层表面，是否能通过某种处理，类似于「抖动」，将原本孤立的严重问题（较小的、深刻的块状划伤）变成更多一些的轻微问题（连续的、浅层的线状划痕）呢？这就是我采用牙膏牙刷大法的逻辑出发点，通过研磨，将严重的划伤弱化，使之淹没在大量轻微划痕中，从而让读碟能力强的光驱（HL-DT-ST - DVDRW GS31N）能够正常抓轨。由于我买了两套，所以可以放心大胆地破坏性处理其中一套的碟片，最后的结果令人欣喜：

抓取成功

小插曲

虽然文中提到的流程并不复杂，但是在实际操作中，我还是历经了好几天的努力、不断地尝试，是的，我对 HL-DT-ST - DVDRW GS31N 本不抱有任何希望，但不曾想到它最后成为了我的大救星。但我必须要指出的一点是，Log 能拿到 100% 的评分，不代表抓轨结果一定完全精确：

各项指标看起来完美，但数据有缺陷的 Log

请关注第七轨，CTDB 显示，它与其他八份抓轨存在一个采样的差别。如果出错，而且错误完全一样，那得是多小的概率！值得一提的是，这份第四张碟是未经过研磨处理的，于是我换了研磨过的那张尝试，得到了：

老铁，没毛病！这个实例告诉我们，即使 Test & Copy CRC 完全一致，也不代表万事大吉。关于问题满分抓轨的更多探讨，可以参见音轨间隙长度溢出问题研究，本文就不加以赘述了。

总结

EAC 虽然已经是我们能使用的最优选，但也并非正确设置后就毫无破绽，无论是糟糕的碟片，还是差劲的光驱，都有可能限制它的发挥。Log Checker 比之 EAC，距离 CD 就又远了一层，即使是 100% 的抓轨，若细究其内容，也可能发现问题的蛛丝马迹。但对于一般用户而言，100% Log 抓轨已经足够可靠。同时，也欢迎大家分享自己的「怪异」抓轨。

最后是一点建议：在使用破坏性处理前，最好买两份，便于留档和对比。CD 处理有风险，下手须谨慎。
