AAM：自动声学管理 (AAM: Automatic Acoustic Management)

AAM is an abbreviation of "Automatic Acoustic Management".

AAM是“自动声学管理”的缩写 。

It is a system of practice for diminishing acoustic emanations in AT Attachment (ATA) mass storage devices for computer data storage, such as ATA hard disk drives and ATAPI optical disc drives. AAM is a permissive attribute set for ATA/ATAPI devices; when a device supports AAM, the acoustic management frameworks are modifiable and adaptable through a software or firmware user interface.

它是一种用于减少AT附件(ATA)大容量存储设备中用于计算机数据存储的声音散发的实践系统，例如ATA硬盘驱动器和ATAPI光盘驱动器。 AAM是ATA / ATAPI设备的允许属性集； 当设备支持AAM时 ，声学管理框架可以通过软件或固件用户界面进行修改和调整。

细节 (Details)

• The ATA/ATAPI sub-command for establishing the standard of AAM operation is an 8-bit value from 0 to 255.

  用于建立AAM操作标准的ATA / ATAPI子命令是从0到255的8位值。

• The majority of current drives ship with the seller-described value of 0x00 in the acoustic management establishment. This frequently decodes to the max-performance value of 254 declared in the standard.

  在声学管理机构中，大多数当前驱动器出厂时都带有卖方描述的0x00值。 这经常会解码为标准中声明的最大性能值254。

• Values between 128 and 254 (0x80 - 0xFE) allow the attribute and opt for or choose most-quiet to most-performance establishments along with that series. Nevertheless, hard drive manufacturers may sustain the entire series of values, the establishments are enabled to be banded; therefore a lot of values could make available the similar acoustic performance.

  介于128到254之间的值(0x80-0xFE)允许该属性，并随该系列选择或选择对性能最佳的场所最安静。 但是，硬盘制造商可能会维持整个系列的价值，这些机构可以合并在一起。 因此，许多值都可以提供类似的声学性能。

• In the process of making available best acoustic performance, several drive manufacturers may restrict the highest seek velocity of the heads for AAM operation.

  在提供最佳声学性能的过程中，一些驱动器制造商可能会限制AAM操作的磁头的最高寻道速度。

• This debase performance by raising the standard seek time: several head movements are enforced to stay remain a supplementary disk rotation before accessing data for the reason that the head was not capable to shift to the objective position in the duration of the first rotation due to velocity restrictions.

  通过延长标准查找时间来降低性能：由于访问头由于速度而无法在第一次旋转期间移动到目标位置，因此在访问数据之前强制执行几次磁头移动以使其保持磁盘补充旋转状态限制。

历史 (History)

• INCITS, which was in earlier times known as NCITS, first processed by the implementation and development of technical standards of AAM in the ATA/ATAPI-6 specification.

  INCITS(以前称为NCITS)首先由ATA / ATAPI-6规范中AAM技术标准的实施和开发来处理。

• AAM is no longer accessible for Seagate and Western Digital drives.

  希捷和Western Digital驱动器不再可以访问AAM。

• In 2008, Seagate took away or eliminated AAM abilities from all its drives for the reason that Convolve claimed that one of its patents, US Patent No. 6,314,473 covers up AAM technology.

  2008年，希捷从其所有驱动器中取消或取消了AAM功能，原因是Convolve声称其专利之一(美国专利号6,314,473)涵盖了AAM技术。

• In 2011, Western Digital started doing a similar act, devoid of making any official announcements, nor upgrading their product documentation.

  在2011年，Western Digital开始采取类似的行动，没有发布任何正式声明，也没有升级其产品文档。

• In March 2012, the product specification sheets go on to allege that there is a variety of seeking methods or approaches on their drives. On the other hand, the hardware that is at the present manufactured does not enable control over AAM.

  2012年3月，产品规格表继续声称其驱动器上有多种寻找方法。 另一方面，目前制造的硬件不能控制AAM。
