碟片制造工艺流程
HDD areal densities have been growing at compound annual growth rate of 60 -- 100% for many years. This trend does not seem to be abating with growing demand for conventional computers and new emerging markets such as consumer electronics. SHDS continues to advance its technology to keep pace with this burgeoning market.STEP 1 - Substrates
3.5" aluminium or 2.5" glass substrates are processed.
STEP 2 - Texture
Substrates are polished to create texture patterns on the disk surface. Texturing is done for the purpose of removing substrate level defects. In addition inducing a specified level of roughness to prevent stiction between the head-disk interface. Finally it is done for aiding magnetic anisotropy in the sputtering process.
STEP 3 - Wash
All particulate contaminations must be removed and the disk surface must be perfectly cleaned and dry before entering the vacuum sputtering process.
STEP 4 - Sputter
Magnetic thin film layers are sputtered onto the disk surface Areal densities for media are primarily determined by this process. Substrates take on magnetic properties after various layers of magnetic alloys are sputtered onto them. A carbon layer finish is applied to make the media more robust and durable.
STEP 5 - Lubrication
A layer of solvent based lubricants are coated over the disk surface to enhance durability and media reliability performance.
STEP 6 - Tape Burnish
An abrasive tape is used to remove any asperities on the disk before testing.
STEP 7 - Testing
Disk is sent for mechanical and parametric testing.
STEP 8 - Packing
All disks that pass testing are then sealed in a vacuum package, ready for shipment to customers.

这就是卖的东西，别上当，看不懂的~~~对修盘没什么用~~~ 楼上的 你就这点水准吗 我说过对修盘有用嘛 本来这些都是猎奇的东西 增加知识面的 你给我来一句对修盘没用 那你本事好 说点有用的吧 行不你不看也就罢了 这个论坛的宗旨是必须要对修盘有用才能发吗 。何况我也事先打了预告的 我辛苦找一阵子 收2元的辛苦费不过分吧 站着说话不腰疼 看了就算是出去吹牛逼也多点谈资好不好！！！！真是XX吐不出象牙 晕，都是一些什么东西啊，我还以为是工厂制作的流程呢。 不是工厂的制作流程是什么 看不懂就不要乱发言 现在的人真是急功近利 就喜欢谁发点什么固件啊 技术啊 这些玩意 从来没有打算从根本上去理解硬盘究竟是怎么回事。 呵呵，盯上梭子你了，这个我不太好管的哟 不說不知道，碟片是用鋁或玻璃造的。 都是一些什么东西啊
如果能找到图片就更好了！ 梭鱼 发表于 2012-5-30 22:39 static/image/common/back.gif
楼上的 你就这点水准吗 我说过对修盘有用嘛 本来这些都是猎奇的东西 增加知识面的 你给我来一句对修盘没用...
梭鱼，犯不着生气嘛！
