disk platter

基本解釋

Figure 2 illustrates the actual storage position on the physical disk platter.
圖 2 描述了物理磁盤盤片上的實際存儲位置。
The average rotational latency is one-half of a revolution of the disk platter.
平均旋轉(zhuǎn)等待時間指的是磁盤旋轉(zhuǎn)一半的時間。
This is due to how WebSphere MQ accesses the disk: essentially, MQ can only respond to the commit() when the relevant part of the disk platter has spun past the drive head.
這歸因于 WebSphere MQ 訪問磁盤的方式：實質(zhì)上，MQ 只能在磁盤的相關(guān)部分轉(zhuǎn)過磁盤頭時才響應(yīng) commit()。
