    摘要： Methods and apparatus for processing a seek request on a disk drive apparatus having a disk drive head is disclosed. The seek request is processed. During the seek request, the disk drive head is traversed across an actual distance. At least one expected seek time associated with the actual distance is obtained from a set of seek time data. One or more measurements are performed on the disk drive apparatus to obtain an update value. At least one expected seek time is then updated such that at least part of the update value is included in the at least one expected seek time.

    摘要： A drainage track useful in combination with exterior insulation and finish systems including a clog-resistant drainage channel so that water collecting behind the exterior insulation and finish may drain from the structure. The drainage track, in a preferred form, is extruded from PVC and defines a substantially L-shaped configuration in cross-section. An elongated, relatively tall flashing leg is provided for attachment of the drainage track to the structure such that all water resistant material and insulation laps over the flashing leg to direct water into the drainage channel. Finish apertures are provided through a portion of the drainage track so that exterior finish such as, for example, stucco, will readily adhere and bond to the drainage track.

    摘要： A method and apparatus for reducing seek acoustics in a disk drive using feedback during large current transitions is provided. A desired transition profile, which uses feedback, is followed in order to smoothen transitions of a commanded current profile that is supplied to a VCM for moving a head relative to a disk surface during a seek operation. Linear interpolation is used to provide feedback for following the desired transition profile.

    摘要： A method for improving disk drive performance by reducing the overhead associated with the command processing code requesting a seek. As multiple commands are queued up in a command queue, a next command is identified and immediately stored in a servo position queue, as soon as the next command location is determined. Therefore, as the drive electronics are prepared for read and write operations, the servo system initiates the actuator to move the read/write head to the next command location. By the time the read/write head arrives at the next command location, the drive electronics are ready for the read/write operation. As a subsequent command is determined, its location is again entered into the position queue, overwriting the previous command location.

    摘要翻译： 一种通过减少与请求寻找的命令处理代码相关联的开销来提高磁盘驱动器性能的方法。 当多个命令在命令队列中排队时，一旦下一个命令位置被确定，下一个命令被识别并立即存储在伺服位置队列中。 因此，随着驱动电子器件准备进行读写操作，伺服系统启动执行器以将读/写头移动到下一个命令位置。 在读/写头到达下一个命令位置时，驱动电子设备就可以进行读/写操作了。 随后的命令被确定，其位置再次进入位置队列，覆盖先前的命令位置。
