    • The present invention may be embodied in a method, and related apparatus, for determining a repeatable runout (RRO) compensation value sets for a plurality of tracks on a disk in a disk drive, wherein the disk drive is initially manufactured and then shipped for installation in a host system. Each track comprises a plurality of embedded servo sectors that define a circumferential path that may have RRO requiring compensation during track following. The method comprises determining first RRO value sets for a first portion of the tracks to a first desired learning level by measuring the RRO for the first portion tracks based on a first predetermined number of disk rotations during the initial manufacturing of the disk drive. The first portion tracks are not adjacent to each other. Then, after the disk drive is shipped for installation in the host system, RRO value sets are determined for a second portion of tracks to a second desired learning level by measuring the RRO for the second portion tracks based on at least a second predetermined number of disk rotations. The learning technique of the invention allows the disk drive to be shipped for installation in a host system with a portion of its tracks having little or no RRO compensation. After shipment, the disk drive may continue to improve the RRO compensation until all of the tracks have been optimally compensated. Thus, the learning technique allows maintained manufacturing throughput without unnecessarily increasing manufacturing costs for high data storage capacity disk drives.
    • 本发明可以体现在用于确定磁盘驱动器中的盘上的多个轨道的可重复跳动(RRO)补偿值集合的方法和相关装置中,其中磁盘驱动器最初被制造并且然后运送以进行安装 在主机系统中。 每个轨道包括多个嵌入式伺服扇区,所述多个嵌入式伺服扇区限定了在轨道追踪期间可能需要补偿的RRO的圆周路径 该方法包括通过基于磁盘驱动器的初始制造期间的第一预定数量的盘旋转来测量第一部分轨迹的RRO,来确定轨道的第一部分的第一RRO值集合到第一期望学习水平。 第一部分轨道彼此不相邻。 然后,在磁盘驱动器被运送以安装在主机系统中之后,通过基于至少第二预定数量的第二部分磁道测量第二部分磁道的RRO,将轨道的第二部分确定为第二期望学习电平的RRO值集合 磁盘旋转。 本发明的学习技术允许磁盘驱动器运输以安装在主机系统中,其一部分磁道具有很少或没有RRO补偿。 装运后,磁盘驱动器可以继续改善RRO补偿,直到所有轨道都被最佳地补偿。 因此,学习技术允许维持制造量,而不会不必要地增加高数据存储容量盘驱动器的制造成本。

    • An electrically insulative shield is disclosed for engaging and covering a device in an electrical circuit. The shield includes a generally planar portion having first, second and third edges. When the shield is engaged to the device, these edges correspond generally in position to the first, second and third sides of the electrical device. A first gripping member extends outwardly from the planar portion adjacent the first edge. The gripping member includes an apertured portion for receiving a projection formed on the first side of the device. A first outwardly extending gripping hook member is provided adjacent the second edge. The first hook member grips a projection adjacent the second side of the device. A second outwardly extending gripping hook member is provided adjacent the third edge of the planar portion. The second hook member grips a projection adjacent the third side of the device.

    • The present invention may be embodied in a method for minimizing adjacent track data loss due to a shock event occurring during a write operation in a disk drive. The method includes providing a plurality of adjacent concentric data tracks, for storage of user data, that are spaced-apart by a track pitch. The plurality of data tracks are allocated into a first set and a second set such that the data tracks of the first and second sets are interleaved physically with one another. A first series of logical block addresses are assigned to the first set of data tracks such that the first series of logical block addresses are consecutively numbered between successive ones of the first set of data tracks. A second series of logical block addresses, which consecutively follow the first series of logical block addresses, are assigned to the second set of data tracks such that the second series of logical block addresses are consecutively numbered between successive ones of the second set of data tracks. The assignment of logical block addresses to the first and second sets of data tracks results in the disk drive postponing writing to the second set of data tracks, thereby reducing data loss due to a shock event causing adjacent track encroachment occurring prior to writing to the second set of data tracks. The disk drive may postpone writing to the second set of data tracks by first writing user data to the data tracks of the first set until substantially all of the data tracks of the first set have been written with user data.
    • 本发明可以体现在一种用于最小化由于在盘驱动器中的写入操作期间发生的冲击事件而导致的相邻轨道数据丢失的方法。 该方法包括提供多个相邻的同心数据轨道,用于存储由轨道间距间隔开的用户数据。 将多个数据轨道分配到第一组和第二组中,使得第一组和第二组的数据轨道彼此物理交织。 第一系列逻辑块地址被分配给第一组数据轨道,使得第一系列逻辑块地址在连续的第一组数据轨道之间连续编号。 连续跟随第一系列逻辑块地址的第二系列逻辑块地址被分配给第二组数据轨道,使得第二系列逻辑块地址在连续的第二组数据轨道之间被连续编号 。 将逻辑块地址分配给第一和第二组数据轨道导致磁盘驱动器将写入推迟到第二组数据轨道,从而减少由于在写入第二组之前发生相邻轨道侵入的冲击事件导致的数据丢失 一组数据轨道。 磁盘驱动器可以通过首先将用户数据写入第一组的数据轨道来延迟写入第二组数据轨道,直到第一组的基本上所有的数据轨迹已经被用户数据写入。
