摘要： a seek procedure for a hard disk drive which provides a significant reduction in acoustic noise as well as high performance fast seek times is described. The seek procedure lowers the peak acceleration for short seeks and imparts a smooth transition from a sine seek to an exponential arrival at the target track. The seek procedure provides an error free feedforward signal derived from a single sine table. The procedure which contains a time domain sinusoid acceleration feedforward combined with a phase-plane trajectory controlled velocity which, near seek completion. The procedure is constructed so that the acceleration begins at zero and, in the fashion of a sine, increases to a maximum, decreases to a minimum and then increases again until a computed switchpoint is reached. The switchpoint is determined in-situ, to provide a smooth and continuous velocity transition from sinusoid to exponential. The velocity trajectory is computed from a look-up table. The procedure is implemented using conventional seek controller servo components and commercially available operation software.

摘要： A packaging arrangement for smoothly and conveniently providing small hardware items to an assembly line operator is described. The items are fastened onto a flexible band, lined up in the order in which they are to be installed on an article being assembled. The band is divided into equal segments defined by index marks, each segment containing the hardware items required for the assembly of one article. The items are fastened to the band off-line using securing features fashioned from the band itself in a manner and orientation by which each item can be plucked from the band with a tool that can grasp the item, pull it off the band, transport it to the article being assembled, and install it on the article without intermediate disengagement from the tool. The utilization of the band improves the productivity and reliability of manually assembled articles such as disk drives.

摘要： A method for operating a fixed media hard disk drive using a plurality of disks on each of which the ratio of servo track pitch to data track pitch is smoothly varied across the surface of the disk as data is being written. The method allows the density of data on each disk to be independently varied, the total data capacity of a disk to be independently varied and introduces a degree of flexibility into the process of testing disk formatting. The method includes the use of a smooth and continuous function having a set of adjustable parameters, by whose definition a relationship between the two pitches is established within the data band. The method can also be applied to disks that are divided into radial zones to take advantage of additional properties of data writing and reading within a hard disk drive.
