In today’s world of rapidly developing technology,
在技术迅猛发展的今天
there are an ever-increasing number of technical standards and formats.
文件格式和技术标准的种类增速空前
And every time a new format is created,
每当一种新的格式问世时
its creators suddenly find themselves tasked with
设计者都会忽然发现自己需要想办法
figuring out some way of distinguishing this format from all the other ones.
把该格式与其他格式区分开
Now, often times you can use simple physical characteristics,
一般情况下可通过简单的物理特征区分
but that doesn’t necessarily indicate what the format is.
但这仍不足以标识其格式
For example, compact discs and DVDs look virtually identical,
举个例子 CD(Compact Disk)和DVD的外观看上去基本相同
and while an eagle-eyed person obsessed with technological trivia
虽然对于那些眼力出众的技术极客来说
can figure out the differences soon enough
可以很快发现两者的差异
It helps to create some sort of logo.
但能有个标志用来辨识就更好了
This logo isn’t just there for identification purposes, either.
标识也不单是用来区分文件格式的
In its traditional use,
按照惯例
it signifies compatibility with the technical specifications of the format.
它还表明了该格式技术规格的兼容性
For example, the venerable VHS cassette.
列如 就“久远的”的VHS录像带而言
This mark isn’t simply descriptive.
这个标识并不仅仅是描述性的
It appears on all videocassette recorders that use the VHS specifications,
它出现在所有使用VHS规格的录影机上
it appears on all video cassettes that use the VHS specifications,
也出现在所有使用VHS标准的录影带上
and it doesn’t appear on cassettes or recorders
而那些不兼容VHS的卡带和录影机上
that don’t use the VHS specifications.
就不会出现该标识
So, even though a quarter of a century passed
因此即便这两台卡带录影机的生产日期
between the manufacture of these two machines,
间隔了25年的时间
because they both have that little logo on it,
由于两台机器上都有这个标识
we can rest assured that a recording made
我们依然可以确信 这个机器录的带子
with this machine will play on this machine, and vice versa.
一定可以在另一个机器上播放 反之亦然
And that’s the point to these labels.
这正是这些标签的用途
Every format has some sort of mark for compatibility.
每种格式都有其特有的兼容性标志
The Compact Disc logo indicates compatibility
例如Compact Disk的标志代表着
with Compact Disc players,
该设备兼容CD光碟
and if I might add
这里我要补充的是
I think that this logo is starting to dip into the retro-cool category.
我认为这个标志已经带点儿复古酷的范儿了
Something about it is just a delightful mix of futuristic, retro,
在它的身上 未来与复古
and wholesome…
以令人愉悦的方式完美结合
Anyway, yes this logo would get little additions underneath it
总而言之 这个标志下面的确会有一些附加说明
to distinguish all the various versions of CD that eventually came about,
用以区分后来出现的各种不同格式的CD
but you’ll find this
但你会发现
Compact Disc mark on any player designed to…
在所有能放CD的播放器上
play them.
都能找到这个Compact Disk标志
Just match up the symbol on the disc
我们只要看到
with the symbol on the player
碟片与播放器上的标志匹配
and you’ll be sure of compatibility.
就能确定它们兼容
Same goes for DVD.
对DVD来说也一样
Does this disc have the DVD logo? Well,
这张碟片有DVD的标识吗?
so does your player.
对吧 你的播放器上也有
Same goes for USB.
USB也是一样
Do you see the pitchfork of knowledge?
当看见这个类似三叉戟图标的时候
Then that’s a USB device.
就表明那是个USB设备
Of course, thunderbolt over USB-C along with power delivery
当然 雷电接口(并非苹果的闪电Lightning) USB-C接口 还有电源接口
is making this increasingly more confusing
长得都差不多 更加令人疑惑
but let’s hope we get that sorted soon.
让我们期待在未来可以改良
And while we’re at it,
既然我们说到这个了
thanks to Pioneer and their near-complete dominance over the format,
多亏了“先锋”在光盘领域近乎处于独家垄断的地位
we call these things Laserdiscs
我们统称这种东西为“LD(镭射/激光光盘)”
without realizing that
而没有意识到这个名称
laserdisc and in particular this logo,
尤其是镭射光盘这个标识
is what Pioneer decided to brand their players
只是先锋公司依照镭射影碟的标准
and discs following the Laservision videodisc standard.
给他们的播放器加的标识
Guys, I’m trying to demonstrate the usefulness of these symbols
朋友们 我在努力向大家解释这些标识的用处
and here you are mucking it up.
而这里是你们最容易搞乱的
The designers (and patent holders) of whatever system we’re talking about create these
我们探讨这些体系的设计者和专利持有者们 他们创造这些标识
symbols not only to demonstrate compatibility for the benefit of consumers,
不仅仅是从用户角度出发标识其兼容性
but also to enforce it from manufactures
更是为了用其来规范生产
and collect those sweet, sweet licensing fees in the process.
并在此过程中 躺着收取授权费用
[♫ upbeat promotional music ♫] Do YOU want to manufacture compact disc players?
你想制造CD机吗?
Sweet!
很好
Just pay us an exorbitant fee,
只需付给我们一大笔费用
and then we’ll give you the knowledge you need to build your CD player!
我们就会给你提供制作CD机所需的相关信息
Then, we’ll charge you a few dollars
然后 你每制作一台CD机
for each player you make, and then,
我们都会收取几美元
and ONLY then, can you put our coveted little logo on it!
之后 只有这个时候 你才能在上面加上我们的标识
It does protect consumers,
我想这的确保护了消费者的权益
I guess, but most importantly it makes us MONEY!
但最重要的是 它可以给我们带来收益!
And it wasn’t just players.
不仅仅是播放器
As recently as 2001,
早从2001年起
Sony and Philips were collecting royalty fees for discs, too.
索尼和飞利浦还开始收取光盘的版权费
At that time, Philips got 1.8 cents per disc,
那个时期 每卖出一张光盘 飞利浦公司获利1.8美分
and Sony got 1.2 cents per disc.
索尼则得到1.2美分
That might not seem like much,
可能看起来不是很多
but considering how many copies of albums were being sold,
但是考虑到市场上有多少张专辑
that’s still plenty huge.
这仍是一个巨大的数字
For example, Linkin Park’s debut
例如“林肯公园”的首张专辑
album Hybrid Theory sold 27 million copies worldwide,
《混沌理论》在全球范围内销售了2700万张
meaning that Philips made ne arly half a million dollars,
这意味着飞利浦赚了近五十万美元
and Sony raked in $ 324,000.
索尼也狂揽三十二万四千美元
So while this little logo may seem like a simple compatibility mark,
所以尽管这个小商标看起来只是一个简单的兼容性标志
it was also a serious money maker.
它同时也是一个强大的造钱机器
But now we come to the meat and potatoes of this video;
那么现在 我们进入这个视频的正题部分
SD cards.
SD卡
I think it’s safe to say that SD has come to prominence
我想我们可以说 SD卡已经
in the removable flash media market.
统治了可移动闪存媒体市场
And just like all the other standards both flash and otherwise,
正如其他规格的闪存 或其他存储设备一样
SD uses a logo to both
SD卡用一个标识
ensure and enforce compatibility.
来标识并规范其兼容性
SD stands for Secure Digital,
字母SD代表安全数码(Secure Digital)
although I prefer to think of it as super dope
尽管我更倾向于把它理解为超级强(Super Dope)
and the SD Association is who makes the rules.
但毕竟SD协会才说了算
The SDA is way less in it for the money,
SD协会并不是为了赚钱
as they are a nonprofit group
因为他们是一个非盈利团体
and only charge$2,500 to join.
并且只要2500美元作为准入金
As far as I can tell,
据我所知
they don’t assess a fee to their members
他们并不会在其成员生产闪存卡
on a per-manufactured-card basis to use that logo.
并使用SD标识的时候收取费用
Their self-described function is as follows:
他们对SD卡功能的自我描述如下:
“The SD Association establishes
SD协会为SD闪存卡投入建立了
the technical and specification standards for SD memory card applications,
各项技术和参数标准
continuously promotes SD as the leading industry standard,
不断加以改进 使其达到行业领先地位
and encourages the development of digital A/V, wireless communication,
并且依托SD独一无二的技术优势
and digital networking products that utilize the many unique benefits of SD standards.
促进数-模信号转换 无线通信和数字化网络产品的发展
Fun stuff.
非常有趣
But, about that logo.
但是 关于那个标志
Why is the D in SD…
为什么SD中的字母D
a disc?
是一张光盘的样子?
I’m fairly confident that this isn’t a disc,
我很确信这里面没有什么“盘”
but I’ll ask my sources.
但我会问一下我的“线人”
Is this a disc?
这是个“盘”吗?
No, it’s not a disc!
不 这不是“盘”!
Is this a disc?
这是个“盘”吗?
Yes all signs seem to indicate that this is indeed not a disc.
是的 所有线索表明这的确不是一个“盘”
Well, that settles it.
好了 问题解决了
Two out of two sources agree that this is not a disc.
二分之二的“线人”都认为这不是一个“盘”
So, um, why is there a disc in the logo?
那么 为什么在这个标识里会出现“盘”的符号呢?
Well, you know how sometimes a company announces
如你所知 当一家公司宣布
that they’re gon na develop a thing,
他们即将开发一个产品
and then they put a lot of R & D effort
然后为了开发工作 他们投入了
into developing the thing,
大量的人力物力
but it turns out that another set
结果却发现其他的公司
of companies is ALSO developing a thing,
也正在研发这件东西
and now you’ve got a situation of two competing things?
那么现在你就面临两个产品相互竞争的处境
That happened in the developmental stages of DVD.
这种情况在DVD的开发过程中就出现过
Philips and Sony were backing an updated version
飞利浦和索尼在着手
of their very own Compact Disc,
升级他们的压缩光盘(Compact Disk即CD)技术
which they called the MultiMedia Compact Disc or MMCD.
他们称之为多媒体压缩光盘技术 简称MMCD
Meanwhile, all of these other manufacturers were backing a different kind of disc.
与此同时 还有其他厂商在研发一种不同的光盘技术
That disc had a different name from MultiMedia Compact Disc.
这种光盘技术和多媒体压缩光盘技术(MMCD)命名不一样
See, what makes DVDs able to store more data than a CD
你看 DVD之所以能比CD存储更多数据
is that the pits are packed more densely.
是因为DVD的数据记录点密度更大
This new disc had a greater pit density than a CD.
这种新型光盘比CD的数据记录点密度大得多
In fact, you might say its density was kinda super.
事实上 你可以说它的数据记录点密度超级大
It was a super density disc.
它就是超高密度光盘(Super Density)
SD!
也就是SD盘
Toshiba designed this logo for use in the never realized Super Density disc.
东芝设计这个标志本来是用于其超高密度光盘的 但其最终并未推广
I’ve mentioned this before in my video
我曾经在介绍
introducing the DVD and its murder of Laserdisc,
DVD打败激光唱盘的视频中提到过这件事
but the creation of the DVD standard hinged
但DVD标准的建立
on the aforementioned companies coming to an agreement
最终有赖于上述公司
on which format to use.
在格式标准问题上达成的共识
This agreement was in large part forced
该共识很大程度上是由计算机公司强制推行的
by computer companies, who envisioned using this
他们设想将此标准用于数据储存
standard for data storage, and who didn’t want to pick sides
但他们不想选边站
and wind up on the wrong one.
因为这样很可能选错技术路线
When the companies agreed and morphed the competing standards into the one,
当各个公司最终同意 将标准统一为
the only, the glorious DVD,
独一无二的 辉煌的DVD标准时
suddenly Toshiba had this useless logo that they designed sitting around.
东芝突然想到了他们之前设计但弃用的标志
And, rather than be wasteful about it,
东芝没有浪费它
they slapped it onto a new flash memory standard.
而是用它来冠名这个新的闪存标准
Sandisk and Matsushita partnered with Toshiba,
在闪迪 松下和东芝合作之下
and the Secure Digital format was born.
安全数字格式(SD)诞生了
Just to add to the trivia,
补充一些细节
SD was essentially just a modification
SD本质上只是对早期的
of the earlier MultiMediaCard (MMC),
多媒体卡(MMC卡)的一个修改版
but support for DRM was added as part of its specifications.
但作为其规范的一部分 添加了对DRM(数字版权管理)的支持
It is likely ( though I have not confirmed it )
很可能(虽然我没有验证过)
that its name was chosen because it was
之所以选择这个名字
designed to fit within the Secure Digital Music Initiative,
是因为它的设计符合《安全数码音乐计划》
which was essentially the record industry’s last ditch effort to
这个计划可以说是唱片业最后的挣扎了
try and get tech companies to move away from MP3s
唱片公司一直试图让科技公司放弃MP3格式
and into a more locked down standard.
而改用一个更有利于版权保护的标准
It didn’t work, but the name stuck anyway.
这个尝试没有成功 但这个名字保留下来了
From my perspective, it looks very much like Toshiba,
依我看 看起来就像
having created this logo,
东芝创建了这个标志
set out to make a new memory card standard,
开始制定一个新的存储卡标准
and the Secure Digital Music Initiative just sort
《安全数码音乐计划》只是
of fell into their laps.
落入了他们的圈套
They designed it to work within that initiative,
他们最初的设想是用技术标准服务于该计划
and if music were to be distributed on cards,
如果把音乐录在存储卡上发售
it might be helpful to put a disc in the logo because,
那么在商标中包含光盘图案就比较好
you know, that’s what music used to go on.
因为 你知道 这就是过去音乐的载体
Anyway, regardless of what exactly transpired,
无论如何 不管到底发生了什么
we do know for sure that this logo is a leftover.
我们已经知道这个标志是一个遗留物
Perhaps you’ve never even noticed that the D is an optical disc.
也许你从来没有注意到这个字母D是一张光盘
I didn’t until I first read about it.
我也是在第一次读到相关文章时才知道
And to be fair,
公平地说
many designs don’t put the little lines through the D
许多标志的字母D上面并没有画那些贯穿的小线段
so it’s harder to make the connection.
所以更难想象这是张光盘
But now that we all know,
但是现在既然我们都知道了
we can laugh at the follies of the past
我们就能自嘲过去的愚昧
and be thankful that the standard endures,
并感谢标准的延续
with one unifying logo letting us know everything we need to….
一个统一的标志能让我们知道一切……
Jeez guys, how many more revisions are you gonna go through?
天哪 你们还要修改多少次?
Won’t you ever be satisfied!
难道你们永远都不会满意吗?
Isn’t half a terabyte on your fingernail enough!?
指甲盖那么大的卡能存下512G数据还不够吗?
I mean really, we’ve got 4K TV now,
我是说 真的 我们现在有4k电视
how much more data are we gon na need?
我们还需要多少数据?
Why don’t you just–
你为什么不……
Thanks for watching,
感谢收看
and I hope you enjoyed this little explanation of the mysterious
希望您喜欢我们这部
disc in the discless format.
关于(标识中字母D上的)神秘的“盘”的小视频
It’s not so much mysterious as much
当我解释清楚之后
as it is a hand me down.
它就显得不那么神秘了
The remains of a project long ago abandoned,
一个被废弃项目的遗留产物
but which ended up being useful after all.
终究被再利用起来
If a little thematically inconsistent.
虽然主题上有点不一致

I got about half-way through the script before I realized
我都录了一半了
that the camera wasn’t recording…
才发现摄像机没有按录像键
and it’s a shame because there were some great bloopers in there.
很遗憾 因为那一遍有许多亮点
To my surprise, while going through DVDs to show the logo,
令我惊讶的是 当我翻看DVD来展示这个标志时
I discovered that Disney DVDs
我发现迪士尼DVD
don’t actually use the official DVD logo.
并没有使用官方的DVD标志
They use their own “ Disney DVD ” thing,
他们使用的是迪士尼自己的DVD标识
which makes me wonder just how they made/make
这让我想知道他们是
their DVDs. Are they correctly licensed and the DVD association (now One-red) just lets them use their own
如何制作他们的DVD的 他们是否获取了正当许可 并且DVD协会(现改称One-Red)
logo?
也同意他们使用自己的标识?
I can’t imagine Disney isn’t being above board,
我相信迪士尼在这件事情上是光明正大的

fits into the whole DVD ecosystem.
是如何融入DVD系统的
Ya know?
