    • A drive roller for use in a conveyor, comprising rotary shafts supported in respective bearings, the respective rotary shafts being provided at the respective ends of a core member and one of the rotary shafts being connected to a drive source. The core member is a hollow- or solid-cylindrical one and has provided thereon and fastened at the respective end portions thereof a tubular inflatable member having at least one inner cord layer in which the cords are laid with a predetermined angle, one end of which inflatable member is fastened to one end portion of the core member while the other end of the inflatable member is folded back inwardly and fastened to the other end portion of the core member, thus a sealed space being defined between the inflatable member and the outer surface of the core member. A fluid passage is formed in the core member to supply and discharge the fluid to and from the sealed space to inflate and deflate the inflatable member, the inflatable member when inflated having a cylindrical outer surface. A to-be-conveyed object is supported and driven only on the outer surface of the inflatable member when inflated.

    • A method for manufacturing a hard-disk drive (HDD). The method for manufacturing a HDD includes writing servo tracks, and writing servo tracks into the HDD using a calculated control target value of a calculated servo pattern overlap amount. Writing servo tracks includes a first, second, third and fourth operation. The first operation includes: producing a first control equation for obtaining a servo pattern overlap amount; and, converting a root-mean-square error (RMSE) into a probability distribution. The second operation includes calculating a second control target value that results in an increased product yield, from the RMSE probability distribution. The third operation includes producing a second control equation for obtaining a calculated servo pattern overlap amount, by assigning the second control target value into the first control equation. The fourth operation includes calculating the calculated control target value using the second control equation and the magnetic-recording-head characteristic value.
    • 一种用于制造硬盘驱动器(HDD)的方法。 HDD的制造方法包括:使用计算出的计算出的伺服模式重叠量的控制目标值,写入伺服磁道,并将伺服磁道写入HDD。 写入伺服轨道包括第一,第二,第三和第四操作。 第一操作包括:产生用于获得伺服模式重叠量的第一控制方程; 并将均方根误差(RMSE)转换成概率分布。 第二操作包括从RMSE概率分布计算导致产品产量增加的第二控制目标值。 第三操作包括通过将第二控制目标值分配到第一控制方程中来产生用于获得计算的伺服模式重叠量的第二控制方程式。 第四操作包括使用第二控制方程和磁记录头特性值来计算计算出的控制目标值。
